Description 1
1.1 Fields of application
The CeSAR slew sway control system for slewing cranes is used to eliminate load swaying movements onslewing cranes. This is achieved by controlling acceleration and deceleration processes.
The sway control system reduces the risk of collisions and accidents while ensuring faster and more accuratepositioning of the load.
It can be employed in manual or automatic crane operation.
The CeSAR slew sway control system can suppress swaying motions in the luffing and slewing directionssimultaneously.
The sway control system is suitable for slewing cranes with rigid boom and also for double jib slewing cranes.
Preconditions for use of the sway control system are that the load is largely guided in parallel by ropes andthat the crane is equipped with continuously controllable luffing and slewing drives.
The CeSAR slew sway control system is designed as an add-on for new or existing crane control systems.
No mechanical damping (sway control) elements are used in conjunction with the CeSAR slew sway controlsystem.
1.2 Versions
1.2.1 Standard version with camera (CeSAR slew)
The standard version of the CeSAR slew swaycontrol system comprises a twin camerasystem with integrated Power PC plus anEthernet-PROFIBUS gateway and RS 232diagnostics module as additional components.
To simplify installation, the additional
components (including power supply) can beshipped preinstalled in a connection box.
A reflector of which the dimensions aredependent upon the working radius of thecrane will also be required.

Description
1.3 Interfacing with the crane control system
1.2.2 Special version without camera (CeSAR slew-blind)
CeSAR slew-blind is designed for use on cranes which cannot be equipped with a camera for design-related
reasons, or which operate in extreme environmental conditions such as extremely dusty atmospheres or atvery high temperatures.
This unit calculates sway solely by means of a mathematical model.
CeSAR slew-blind comprises a Power PC and an Ethernet-PROFIBUS gateway (when it is interfaced toPROFIBUS). The modules can be integrated in any type of control cabinet. No reflector is required.
The special version without camera is capable of eliminating most swaying movements which are generatedby luffing and slewing motions. However, it is not capable of suppressing sway caused by external forcessuch as diagonal pull or wind.
All the functions referring to the camera which are described in this document are deactivated in theCeSAR slew-blind version.
1.3 Interfacing with the crane control system
The sway control system is interfaced with the crane control system by means of Profibus-DP or, optionally,via Ethernet with Internet Protocol (IP) and embedded UDP protocol.
The logical interface is implemented in the form of a defined data structure which is exchanged via the bus.
1.4 Camera measurement (CeSAR slew only)
1.4.1 General
In order to measure load swaying movements, the camera unit must be installed on a horizontal plane closeto the rotary axis of the crane. The angle of aperture is approximately 45°. A reflector must be attached to the
load carrying device.The camera calculates the position of the reflector relative to the crane for as long as it remains within thefield of vision. The data measured in this way are used to determine the swing angle in the tangentialdirection and, by means of a precision distance measurement, in the radial direction.
The advantages of taking measurements by camera as opposed to other measuring methods are listedbelow:
• the camera measuring system is contact-free and thus also wear-free,
• the measurement has an extremely high resolution and
• the actual load position relative to the crane is measured.
1.4.2 Reflectors
For more effective suppression of disturbances caused by sunlight (especially shading and reflections on thereflector) and the suppression of artificial (low-infrared) light sources, the reflectors are equipped with infraredLEDs as well as an infrared-blocking filter for the camera. As a result, the camera evaluates only lightinformation within a wavelength range of approximately 850 nm, which is invisible to the human eye.
The reflector is designed for use under the environmental conditions defined for the scope of application.These include vibration and sea water in particular.
In the event of a measuring system malfunction, the sway control and positioning systems use the swingangle calculated by the internal oscillation model. As soon as measured data become available again, theoscillation model is corrected (if necessary).

Description
1.7 Operating modes
• During slewing operations, the luffing drive eliminates swaying movements in the tangentialdirection,
• In positioning operation, the load only overshoots the target position by a very small amount
The sway control system is configured by means of parameters.
The sway control system receives the required process information via a defined data structure. The inputand output data are normally supplied and further processed by a PLC.
The sway control system calculates speed control values that are forwarded to the drives by the PLC.
In this coupling, the PLC is the master, which uses the sway control system as a service computer tosuppress the swaying of the load.
NOTICE
After an emergency stop, the sway control system must not be reactivated until it has been ensured (onsystems operating without a camera) that the load is not swaying and that the travel signal is brieflycanceled. Refer to Section 3.5.3 for details.
1.7 Operating modes
1.7.1 Speed control mode
1.7.1.1 Manual speed control
In speed control mode, the speed setpoint is specified by the crane driver. The crane is accelerated or decelerated to this setpoint in such a way that the load has ceased to sway once it is reached.
Speed control mode is activated by setting the corresponding operating mode bit.
In speed control mode with active sway control system (activated by input bit "AS_ON“), the internal setpointacceleration of the slewing gear is dependent upon the current position of the luffing gear. (See illustrationbelow)
Fig. 1-2: Correlation between internal setpoint acceleration (slewing gear) and boom position in speedcontrol mode.
The sway control system can be activated or deactivated by means of command bit "Sway Control ON".When the function is switched off, the controller generates standard ramps according to the set accelerationrates.

Description
1.7 Operating modes
When the CeSAR blind version is installed, sway caused by diagonal pull or wind can only be eliminated bythe crane driver. In this case, the sway control system must first be disabled (by means of bit "AS_On"). Thecrane drive must then carry out compensating movements until the load is stationary. Finally, the travel signal
must be briefly canceled in order to reference the oscillation model to 0. The crane can then be operatedagain with active sway control system.
Internal activation of the sway control system is displayed by means of status bit "Sway control ON".
The sway control function is disabled internally under the following conditions:
• The bit "Sway control ON" is reset.
• The activation speed has not been reached.
• The activation time has not yet expired.
• The bit "Sway control only when stopping" is set. The sway control system is only active whenstopping.
• The hoisting gear is outside the set upper and lower sway control limits.
Hoisting gear movements are possible in active speed control mode and have very little effect on the quality
of the sway control.
Fig. 1-3 shows the slewing operation of crane with a 20 m working radius and 40 m rope length.

The recommended chronological sequence of the signal exchange between the crane PLC and CeSAR aswell as the operator actions during the travel operation are illustrated in the following diagram.

Description
1.7 Operating modes
Fig. 1-4: Signal sequence in speed control mode
For example applications of the signal exchange to be implemented in the PLC, refer to Section 3.5.
The luffing gear must always be activated when a slewing motion is performed to allow the sway controlsystem to eliminate load sway movements in the radial direction.
1.7.1.2 Speed control in Cartesian coordinates
In narrow areas of the vessel or when working in close proximity to a neighboring crane on a vessel, it can beuseful to move the boom tip back and forth along a straight line between the vessel and the land. Control of the slewing crane along straight lines is referred to as "control in Cartesian coordinates". The boom tip
performs a linear movement when the joy stick is deflected.To enable this method of control, the bit "Control in Cartesian coordinates" must be activated in speed controlmode. The direction of the coordinate system (Y°) must be specified as "Slew setpoint position" in the swaycontrol system configuring data.
The diagram below illustrates the action of the setpoint speed or joy stick.

1.7 Operating modes
Fig. 1-5: Speed control in Cartesian coordinates
For example, if the value 8000 (80°) is transferred as the "Slew setpoint position", deflecting the joy stick"Slew" on its own will produce a motion in direction 80°/260° and deflecting the joy stick "Luff" on its own willproduce a motion in direction 170°/350°. It is also possible to actuate both joy sticks simultaneously.
1.7.2 Positioning mode
1.7.2.1 General
Positioning control mode allows the load to be positioned automatically in the slewing and luffing directions. Inposition control mode, a specified target position is automatically approached with active sway control. Load
sway is eliminated both when maximum speed is reached and on completion of the positioning operation.The appropriate operating mode bit must be set in order to activate positioning control mode. Positioningcommences when the travel signal is activated. The luffing gear must always be activated when a slewingmotion is performed to allow the sway control system to eliminate load sway in the radial direction.
The positioning operation can be aborted at any time by setting of the "Controlled stop" signal.
The maximum and minimum positions of position control mode can be defined for the luffing gear by meansof parameters P7 and P8. It is not possible to position loads outside these limits.
In addition to the target position, a slewing direction can also be specified for the slewing gear (see commandbits for luffing and slewing in Table 3-3). The crane then moves to the target position in the selected slewingdirection. If no slewing direction is selected, the crane traverses the path with the smaller slewing angle. It isnot possible to set slewing gear position limits in the sway control system.
NoteThe PLC must monitor the validity of the target position and prevent the crane from travelling throughprohibited slewing zones by specifying the slewing direction bit. If the maximum permissible 360° slewrange of a crane is restricted, the relevant limits must be configured in the PLC.
Fig. 1-6 shows an example of the chronological signal exchange sequence for positioning mode.

1.7.2.2 Positioning in Cartesian coordinates
In positioning mode with Cartesian coordinates, the load is guided along a straight line from the start positionto the target position with active sway control.
To enable this method of control, the bit "Control in Cartesian coordinates" must be activated in positioningcontrol mode.
It must be ensured that the straight line between the start and target positions is positioned such that it doesnot pass closer to the center of rotation of the crane than the minimum luffing gear position. Otherwise, anerror message is output.
WARNING
hen a controlled stop command is issued during a positioning movement in Cartesian coordinates,Cartesian mode is deactivated internally in the sway control system and the axes are stopped separately
ith active sway control. In this case, the crane departs from the programmed straight line.
Parameters P84, P94 and P95 must also be taken into account in relation to parameterization of Cartesianpositioning mode.

Description
1.7 Operating modes
WARNING
It is not permissible to switch over to Cartesian positioning mode when the crane is traveling according to
polar coordinates, nor is it permissible to change between target positions while a Cartesian positioningmovement is in progress. Either of these actions can cause the crane to move unpredictably.
1.7.2.3 Automatic inward luffing (polar coordinates)
Automatic inward luffing functionality is provided in order to optimize positioning travel times.
In most cases, the maximum possible slewing speed of a crane increases in proportion to the proximity of theboom to the center of rotation. Automatic inward luffing makes use of this characteristic.
An example (see Fig. 1-7: Automatic inward luffing) is provide in order to explain the general principle:
During positioning, the luffing gear travels from a start position of 30 m to a target position of 30 m, while theslewing gear travels from a start position of 0° to a target position of 180°. Without automatic inward luffing,the crane travels along the blue line. With automatic inward luffing, the crane travels along the red line.

Fig. 1-7: Automatic inward luffing
Automatic inward luffing can be activated via parameter P92. It defines the radius of forward and reversetravel of the luffing gear during positioning.
If the start and target points do not lie within a circle with the radius defined in P92, automatic inward luffing isactivated.
If both points are located within this circle, automatic inward luffing has no effect and the axes are positionedindependently of one another.
It is therefore possible to deactivate the inward luffing function by setting P92 > P8.
Other aspects of the automatic inward luffing function can be programmed with parameter P93 (see Chapter "Parameter description").

NOTICE
Instructions for use of automatic inward luffing function and switchover of target positions
he following must be implemented in the PLC:If the target position is changed while positioning is still in progress and automatic inward luffing is active,a controlled stop command must first be issued for both axes.
hen the crane has stopped and the travel signal has been canceled by means of signal "Positioningcomplete", the new positioning process to a new target with active automatic inward luffing can be started.
hen automatic inward luffing is deactivated, target positions can be changed at any time.
1.7.3 Sway neutralization mode
The sway neutralization mode (with CeSAR slew only) is used to eliminate swaying movements of the loadfrom standstill.
Sway neutralization is linked to a positioning scenario in which the target position corresponds either to thecurrent boom position or the load position at the instant of activation of sway neutralization.
Sway neutralization results in slight travel movements to both sides of the target position. The signalsequence corresponds to that of positioning.

The camera is calibrated in commissioning step 6.
N
The camera must be calibrated during initial commissioning, or subsequently after camera realignment or replacement of the camera or reflector.
It is irrelevant whether position 1 or position 2 is approached first.
The hoisting gear position applicable to position 1 or position 2 is defined by parameters. The value for position 1 is entered in P68 and the value for position 2 in P69. When commissioning step 6 is completed,positions are automatically a
theccepted and stored in P68 and P69.
The camera calibration process determines the settings of parameters P70, P71, P74 and P75.
Once the camera has been completely calibrated, the parameter changes are automatically stored in the

For a CeSAR slew system with master and slave cameras, the individual components must be connected upas illustrated in the diagram below.
Fig. 2-6: Connection diagram for CeSAR slew
Dashed lines represent a temporary connection for commissioning and diagnostics. Solid connection linesrepresent a permanent communication link.
Each camera must be connected to the hub by means of the uncrossed Ethernet cable supplied with the unit.
All other outgoing camera cables with preassembled connectors must be connected to the appropriate RS232 module. These cables carry the operating voltage, the digital input and output signals and the diagnosticdata.
The gateway must be connected to PROFIBUS and, using an uncrossed Ethernet cable, to the hub. Thisconnection links the camera to the PLC.
The diagnostic PC must be connected to the hub by means of an Ethernet cable. Alternatively or as anadditional connection, the serial port on a diagnostic PC/laptop (e.g. COM1) is connected to the serial port onthe diagnostic module.

Integration in the crane controller 33.1 Overview of CeSAR slew integration structure
The sway control system must be integrated into a conventional crane control system. Data are exchangedbetween the crane PLC and the sway control system by means of a bus system. The PLC remains Master and distinguishes between conventional operation and operation with sway control.
Fig. 3-1: Overview of CeSAR slew integration structure
3.2 Sample interface
The sample interface consists of several functions (FC), function blocks (FB) and data blocks (DB).
The most important relationships are shown in the following figure. All data are stored in data blocks DB83and DB84. The function blocks FB83 and FB84 prepare these data and make them available to the PLCprogram.

3.2 Sample interface
Fig. 3-2: Sample interface
The blocks have the following specific tasks:
1. FB83 Sends current data to the sway control system
Checks the message frame counter received via PROFIBUS and thus whether the last message frame hasbeen sent.
Loads the header data (IP address and port of message frame receiver, control/status word) and the user data from the appropriate data area (DB85) to the I/O output area.
WARNING
Not all data may be transferred as consistent data.
Increments and loads the message frame transmit counter. This counter must be changed if data are to betransferred to the sway control system from the Ethernet-PROFIBUS gateway.
2. FB84 Receives current data from the sway control system
Checks the current receive counter, the IP address and the port of the message frame sender.
Loads the received user data from the I/O input area into the appropriate data area (DB86).
Monitors the watchdog bit.
3. FC1 Jump distributor
Calls the receive block (FB84), the block for the preparation of general data (FC80), the axis-related data(FC81) and the send block (FB83).
4. FC80 Processing of general data
Loads the general send data into the data block (DB85) and returns the receive data from the receive datablock (DB84).
5. FC81 Processing of axis-related data (trolley, bridge, slewing gear)
Loads the axis-related send data into the data block (DB85) and returns the axis-related receive data fromthe receive data block (DB84).

3.3 General requirements, overview
Note
If an interface other than the sample model described above is employed, it is important to note that
the bytes of a word (high-order and low-order bytes) must be used in the correct sequence. Thisapplies to the command, status and error words.
3.3 General requirements, overview
The CeSAR slew sway control system has been tested on both electrical and hydraulic luffing and slewinggear drives.
WARNING
The drive system and all safety functions of the crane, especially limit trips, safety interlocks,EMERGENCY STOP functions and load monitoring must be commissioned and functional.
The following requirements for the commissioning of the sway control system must be satisfied:
All components of the system must be installed, connected, functional and interconnected.
- Prepare the PLC program
- Calculate the crane geometry
- Warm up hydraulic drives
- Prepare the electrical slewing gear drives
- Start the diagnostic program and establish the connection between the commissioning PC and the camera
- Set the access code and the language of the diagnostic program
- Check the communication link between the PLC and the camera measuring system
- Check the camera image
3.4 Preparing the PLC program
3.4.1 Integration into the hardware configuration (GSD file)
Variant 1 (recommended):
Open the sample interface project stored on the product CD (432DWKed) with the Simatic Manager. Copythe Ether Gate 692DP from the hardware configuration and paste it into the hardware configuration of your own crane control project. (In the example project, the PB address is set to 8 by default.) Prepare the PLCprogram such that it can supply all signals for the sway control system and process all output data in therequired way.
Variant 2:Open the hardware configuration of your own crane control project, click on button "Tools", "Install GSD files"and specify the path to the GSD file stored on the product CD. Now install the GSD file. You can load it bydragging it from the "Profile catalog" ("View"Æ“Catalog", "Profibus-DP"Æ"Additional FieldDevices"Æ"Kuhnke"Æ"Ether Gate 692DP") and dropping it into the hardware configuration of the cranecontrol program. You then need to adjust the "Object properties" of the Profibus node. To do this, select theEther Gate 692DP, open the window "Assign parameters"Æ"Device-specific parameters". You must nowaccept and save the settings displayed in the screenshot below.

3.4.2 Inserting interface blocks:
Copy all OB, FC, FB, DB and SFC blocks from the block folder of the sample interface project and pastethem into the block folder of your own crane control project. If this folder already contains blocks with thesame function or title, they must be overwritten or renamed. If it is necessary to rename blocks, existing blockcalls must be programmed with the new titles.
3.4.2.1 Adapting the interface blocks:
Open block FC1 "F_Call_RuntimeGroup".
Check the required timers T1 and T5 in networks 1 and 6 for double assignment elsewhere in the PLCprogram and change them if necessary.
The input and output addresses in networks 1 and 6 must also be adapted. Enter the required addressesfrom the HW configuration of the Ether Gate 692DP (Header Module, Data in 1st Block, Data in 2nd Block,Trailer Module) correctly at the inputs of networks 1 and 6. (Symbol designations of network 1 inputs:I_Adr_Head, I_Adr_DatMod1, I_Adr_DatMod2, I_Adr_Trail, O_Adr_Trail; Network 6: O_Adr_Head,O_Adr_DatMod1, O_Adr_DatMod2, OI_Adr_Trail, I_Adr_Trail)

3.4 Preparing the PLC program
3.4.3 Input and output signals:The PLC program must now be prepared such that it can supply all signals for the sway control system andprocess all output data in the required way. For this purpose, all the required input and output formaloperands (dummies) in FC1 must be exchanged for the corresponding signals used in the program.
The structure of the data transferred from the PLC to the CeSAR computer is as follows:

3.4 Preparing the PLC program
Load weight Load weight (load carrying device plus load) in 10kg steps. The difference between the load weight and loadcarrying device (P89) must not be less than 0 or greater than 100,000 kg.
Various parameters which control how the load weight is handled internally can be set during commissioning.For details, refer to Chapter 4.7Section "Compensate load carrying device".
Actual hoisting / luffing / slewing position The actual hoisting / slewing / luffing positions can increase in any direction. The hoisting gear position inparticular can increase from the ground upwards. The conversion to the effective pendulum length isperformed internally by means of parameters.
The sway control system calculates internally with increasing position values during outward luffing andslewing to right motions. The internal position is calculated (e.g. for slewing) on the basis of
s_act_intern = P25 * s_act + P26.
The parameters P25 and P26 (as well as P5 and P6 for the luffing gear) must be adjusted accordingly toensure that the internal representation corresponds to the real movement.
P80*s_Hoist + P81 is the internally applied hoisting gear position (without load offset). It is limited by
parameters P85 and P86.
Note
The crane control system must monitor the transferred position values for errors, i.e. it must, for example,check the hoisting height for abrupt changes.
Note
The actual values of the luffing gear must not exceed certain limits. For details see Chapter 3.6
Luffing, slewing setpoint positions The setpoint positions refer to the coordinate system of the actual positions. The setpoint positions are
internally represented and converted in the same way as actual positions.
Luffing, slewing setpoint speed The setpoint speed is evaluated in speed control mode. The normalizing value can be set with a parameter.When the default is set, the setpoint speed ranges between +32.767 and –32.767.The setpoint speed must be positive for slewing to right. The luffing gear speed setpoint refers to the luffingdrive. Positive values can thus indicate both inward and outward luffing depending on the kinematiccorrelation between drive and deflection (see also Chapter 3.6).
Note
The input values for v_set must be greater than or equal to -P109 and less than or equal to P109.
Maximum speed
The permissible maximum speeds can be transferred as a function of the working radius and loading of thecrane. The maximum speed for slewing to right and outward luffing must be greater than zero, and less thanor equal to zero for slewing to left and inward luffing.
When these input variables are changed during operation, the internal setpoint speed is reduced at thesetpoint acceleration to the new limit value and the control speed adapts itself to the new limit with activesway control. This means in particular that a certain period of time will elapse until the control speed hasdropped to the level of the new speed limit.

3.4 Preparing the PLC program
Note
The maximum speed values supplied by the PLC while the crane is in motion should always change
continuously (smoothly) as a function of the luffing gear or slewing gear position. Abrupt changes cancause the control speed to change suddenly and thus cause the crane to behave incorrectly. Especially inCartesian mode, abrupt speed changes can cause the crane movements to depart from the programmedstraight lines.
Note
In the case of motion towards the prelimit switch inside the prelimit switch range, the maximum speedvalue is not relevant. Instead, the appropriate prelimit switch speed parameter (P13/P33) applies.
Note
The maximum speeds v_maxf and v_maxb refer to the normalizing value P109 and must not exceed it.
Height above ground In order to calibrate the camera, the current height of the load hook above a fixed reference plane is requiredin addition to the current pendulum length (actual position of hoisting gear). There is a fixed difference inheight between the reference plane and camera. The transferred values can refer, for example, to the heightabove the quay or the upper carriage.
This input variable is needed to perform internal calculations. Its influence can be viewed under "Const. -s_Hoist(2)" in Monitor 1. The value displayed there is the variable A contained in the description of E34("Error hoisting height above ground").
The value "Const. - s_Hoist(2)" must decrease in proportion to the increase in height above the ground and itis relevant only in relation to single-jib cranes.

3.4 Preparing the PLC program
The parameter "Parameter set locked during travel" can be used to specify whether switchover of the currentparameter set is permissible at any time or only when the crane is at standstill.
"Save current image" bit When the signal edge changes from 0 to 1, the current camera image is stored in a file named from Img0.jpgto Img9.jpg. With each new edge change, the digit in the file name is incremented by 1. When Img9.jpg isreached, the process starts again at Img0.jpg. The image data can be accessed via the File Manager inCeCOMM.
NOTICE
Please do not perform this operation while the crane is moving because there is a risk that cycletimes will be exceeded.
NOTICE
To reduce the load on the computer, the "save current image" function should be used only for diagnostic purposes.
Activate digital hoisting distance correction When this bit is activated, a shift in the center of gravity is applied to the effective pendulum length by thedigital hoisting distance correction function (P87). In this way it is possible to manage two different loadcarrying devices and the different influence they have on the effective pendulum length.
Control in Cartesian coordinates Manual operating mode:The joy stick commands are evaluated as control commands on straight lines in an x-y-coordinate system.The origin of the Cartesian coordinate system [0,0] coincides with the origin of the polar coordinate system[0,0]. The position of the Y axis corresponds to the "Setpoint position for slewing" (see Section 1.7.1.2) and
the direction of motion when the "Slew" joystick is actuated.In Cartesian control mode, the travel signal must be set for both axes until the sway control system returnsthe "Positioned" bit for both axes.

Fig. 3-12: Generation of the travel signal
The following must be noted in relation to operation without a camera: It must be ensured that the load is notswaying as the travel signal is set from 0 to 1. This is because the internal oscillation model was set to zerowhen the travel signal was previously canceled. Furthermore, the oscillation model does not take naturaldamping into account. The effect of this in the following situation, for example, is as follows: If the load is
swaying at the end of a movement both in the oscillation model and in reality (e.g. in the case of stoppingwithout active sway control), an oscillation with constant amplitude persists in the model for as long as thetravel signal remains active. In reality, however, the sway continues to diminish over time. If a new movementis initiated after a prolonged period without resetting the travel signal, the sway control system does not workproperly. In this case, it is necessary to wait (as described at the beginning of this paragraph) until the loadsway has been completely neutralized and then briefly set the travel signal to zero. Only then is it permissibleto initiate a new travel movement.
In Cartesian control mode, the travel signal must be set for both axes until the sway control system returnsthe "Positioned" bit for both axes.
If the target position is changed while positioning is in progress, the travel signal must be reset.

3.5.4 Brake control in the PLC
Opening and closing the brake
The brake must be closed if the signal "Positioning complete" is set and output of direction signals hasceased.
Fig. 3-13: Closing the brake
NOTICE
The brake must be opened while a direction of travel signal is set.
Brake control and travel signal
Allowance can be made in the PLC for the scenario in which the crane is not immediately ready to travel after the travel signal has been set, but instead reacts with a delay to control signals issued by the sway controlsystem (e.g. due to the magnetization period required by the drive). To do this, a time delay must beconfigured between cancelation of the "Brake closed" signal and setting of the travel signal. In this case, theCeSAR system will compute the control values only after the "Brake closed" signal has been canceled.
3.5.5 Differences in behavior of internal oscillation models in operation with andwithout activated camera
When the sway control system is operated without active camera measurement (P112=1), the oscillationmodel is set to zero every time the travel signal is canceled. For this reason, the user must ensure that theload is not swaying at the moment the travel signal is set and a movement started. The control values will nototherwise effect correct sway neutralization while the crane is moving.
If camera measurement is active (P112=0), the internal oscillation model is not reset because it can beupdated at any time by measurements. This is obviously completely dependent on proper functioning of thecamera measurement system. If the user wishes the sway control system to behave like a "blind" system inthe event of a camera measurement error (E9 is active), in which case the internal oscillation model will bezeroed when the travel signal is canceled, then this behavior can be implemented by means of a parameter
set switchover. When E9 is active, the input bits Par_Set (Table 3-5) should be used to switch from theexisting parameter set over to a parameter set in which P19 and P39 equal zero. If E9 disappears again, theoriginal parameter set should be selected again.

3.5.6 Control in the "Manual control" mode
In manual control mode, the travel signal is set by operation of the joy stick. If all input signals are error-free,the Sway Control system responds by setting the active signal. With this active signal, the output speed canbe connected as a setpoint source.
If one of the two direction signals is active, the brake must be opened. As long as the brake is closed, nocontrol speed value is output.
The travel signal can be reset when "Positioning complete" is signaled.

3.6 Geometry of the luffing gear
3.6 Geometry of the luffing gear
The sway control system offers a feature which makes it possible to take into account the non-linear relationship between the positions of the luffing gear drive and boom on slewing cranes. For this purpose, thegeometric relationship between the boom and drive must be described in a text file "wippen.txt". Using theinformation in this file, the sway control system can perform an internal conversion from boom position, speedor acceleration into drive position, speed or acceleration. A step in the commissioning process ensures thatthis file is correctly identified and read by the sway control system. There are two possible structures of the"wippen.txt" file. With one structure, the file contains a table. With the other, geometry parameters aredefined. The latter structure can be used only for cranes with a very specific geometrical design.
Each line in the text file which starts with a hash (#) is interpreted as a comment and has no influence onoperation.
WARNING
he content of the file "wippen.txt" has a significant influence on the motion behavior of the crane. It isherefore essential to ensure that the data are correct and have been read in correctly by the sway controlsystem. See also Section 3.6.3

3.6 Geometry of the luffing gear
Note
The luffing gear of the crane must not move outside the range limits defined by the minimum and
maximum boom positions specified in the wippen.txt file. The sway control system cannot accuratelyconvert data outside this range and the actual position value supplied by the PLC is therefore limitedinternally to this range. The limit switches in the PLC must be set accordingly.
3.6.2 "wippen.txt" with geometry parameters
The structure with geometry parameters can be used only for single-jib cranes with the geometriccharacteristics illustrated in the diagram below. In this case, parameter P73 must be set to 1 or 2.

3.6 Geometry of the luffing gear
The text file "wippen.txt" with geometry parameters must be structured as follows:
[Geometry]1
0 <D> <E> <F> <G> <L> <V> <DR> <DS> <name>
In this case, <D>, <E>, etc. are place holders for the values (in millimeters) of the lengths represented in thediagram above. <Name> should be a string containing the name of the crane. For example, if the values for acrane "K1" are
D = 4950, V = 1565,
E = 3500, DR = 1250,
F = 12050, DS = 38,
G = 2400,
L = 50000
the file structure is as follows:
[Geometry]
1
0 4950 3500 12050 2400 50000 1565 1250 38 K1
A table is also computed internally, i.e. the minimum boom position, which equals E+V, is rounded up to thenext whole meter. The maximum boom position, which equals L+V, is rounded down to the next full meter.
When the sway control system has been restarted, it equalizes the non-linearities of the luffing hydraulicsystem.
NoteThe sway control system does not check whether the values of the geometry parameters are consistentwith the crane geometry illustrated in the diagram above. It is the responsibility of the user to check thevalues.
Note
Even when geometry parameters are used, the actual position is restricted in the sway control system.The Note contained in Section 3.6.1 above also applies when geometry parameters are used. In thiscase, the table is generated automatically and the minimum and maximum positions of the luffing boomcan be seen in the commissioning step described in Section 3.6.3.
3.6.3 Commissioning step to check file "wippen.txt"
The sway control system cannot check whether the geometry parameters have been correctly read in fromfile "wippen.txt".It simply displays an error message (E7) if it has failed to read in the data. In this event, theluffing gear cannot be moved.
If data have been read in without issue of error message E7, the commissioning engineer must checkwhether the system has read the correct values. This is done in commissioning step a, see Section 4.5.2.

3.7 Acceleration and deceleration behavior
3.6.4 Limit switches and prelimit switches for the luffing gear as defined in the
sample interface supplied
The limit and prelimit switches for the luffing gear must always be referred to the boom, as illustrated in thediagram below.
Fig. 3-16: Arrangement of limit and prelimit switches.
One exception applies as regards the processing of limit switches in the PLC. If the geometry of the luffinggear is such that the drive position sinks as the boom position rises (this applies in the case of single-jibcranes, for example), the limit switches at the sample interface must be exchanged because the controlspeed sign is the opposite of the boom speed sign. For example, if the luffing gear is at the forwards limitswitch, control speeds greater than or equal to zero are permitted, but not other control speeds.
3.7 Acceleration and deceleration behavior
Load swaying movements on slewing cranes are eliminated by controlling the acceleration and decelerationof the luffing and slewing gear.
The acceleration or deceleration behavior of the sway control system is set by means of three ramps or acceleration values.
The ramp applied in the case of acceleration without sway control/minimum acceleration (P2, P22) isgenerally the same as the ramp along which the boom or drive accelerates when the sway control system iscompletely deactivated. The minimum acceleration rate acts as a limit if one of the following conditions isfulfilled:
• Prelimit switches have been activated
• The crane is being operated by the sway control software, but the bit "Sway control ON" equals"0".
The operating principle of P2/P22 in the event of activation of prelimit switches is as follows (example): In thisexample, it is assumed that the slewing axis is moving in a positive direction and the forwards prelimit switchis activated at a given moment. The internal setpoint speed is then ramped down to the prelimit switch speedand the control speed is reduced accordingly with active sway control. However, an upper limit is applied by abraking ramp which starts at speed v_maxf and brakes according to the value of P22. In other words, if P22and P23 are set to similar values, the sway control function is impaired.
The minimum acceleration parameters have no effect in the normal traversing range. The sway controlsystem can then brake more slowly in order to compensate any load sway.
The maximum acceleration ramp (P4, P24) applies a limit in the opposite direction. The sway controlsystem will never accelerate or decelerate faster than the limits imposed by this ramp. It should ideally be setto the maximum possible physical value.

3.8 Hydraulic drive
The setpoint acceleration ramp (P3, P23) provides the basis for calculating the control speed of the swaycontrol system. However, in order to compensate for any load sway, the sway control system does not rigidlylimit acceleration/deceleration to this ramp.
The following settings are recommended:
• P4, P24: The maximum possible acceleration rate of the drive
• P3, P23: Approx. 75% of P4
• P2, P22: The following condition applies: P2 < P3 < P4 or P22 < P23 < P24. The specific value isdetermined by the position of the prelimit switches relative to the limit switches. At thisacceleration rate, it should be possible to brake the drive from full speed down to prelimit switchspeed between the prelimit switch and limit switch. The optimum values must then be determinedexperimentally on the crane. Compliance with the limit values always has priority over compensation of load sway.
Fig. 3-17: Acceleration and deceleration behavior of the sway control system
Note
Values below 20 (mm/s) cannot be set. When values < 20 are set, the acceleration value is interpreted asa ramp time and made available as a calculated acceleration value.
3.8 Hydraulic drive
If the luffing and/or slewing gear is equipped with a hydraulic drive, slewing and luffing operations must beperformed several times to warm up the drives prior to commissioning. This is especially important for calibrating the luffing speed.

3.9 Preparing the converters
3.9.1 Converter parameter sets
Two parameter sets should be available for the converters.
The first parameter set is used for the conventional crane control without sway control when damage occurs.The normal acceleration and deceleration ramps must be set there. The second parameter set is used for thesway control function. The setpoint is supplied continuously by the sway control system. The parameters areset as described in the following sections.
3.9.2 Acceleration and deceleration ramps
The acceleration and deceleration ramp times must be set to the lowest reasonably acceptable values for thedrives and mechanical components.
CAUTION
he ramps provide Emergency Stop functionality in the event of a fault.
NOTICE
cceleration and deceleration ramps that are too slow can cause swaying movements!
CAUTION
he sway control system can briefly calculate higher accelerations and decelerations than those thatoccur in normal travel operation – especially when neutralizing large swaying movements.
3.9.3 Initial and final rounding
As the speed characteristic is defined by the sway control system, initial and final rounding functions shouldbe deactivated.
NOTICE
Excessive roundings in the converter can cause swaying movements!
3.9.4 Minimum frequency of the converters
In order to be able to eliminate small swaying movements after stopping, the minimum frequency of theconverter must be set to 1 Hz or lower.
NOTICE
If the minimum frequency is too large, the residual swaying movements may be relatively large and thecrane will not or only rarely come to rest!

3.9.5 Speed controller of the converter
The internal speed control of the converter can be activated in order to achieve the best possible control
response. In addition to the proportional component, an adequate integral component should also beset. Good results have been achieved for the Simovert with kP = 3..5 and Tn ≤ 200.
3.9.6 Limitation of the speed control signal
Note
Configuring limits for the control signal in the converters can cause sway neutralization problems (residualsway), because the internal oscillation model does not represent the real movement of the load in suchcases. A following error can also develop in positioning mode. Limits applied in the converters must nottherefore be allowed to affect the control values of the sway control system.
As a general rule, speed limits in the sway control system must be implemented by means of the
corresponding parameters and/or the input variables from the PLC. A following error is the difference between the calculated and the actual position of the crane (deviationbetween setpoint and actual value).

4.1 Brief guide
1. Connect up components, connect up PROFIBUS and the power supply
1.1 CeSAR slew
− Connect the camera cable to the RS-232 module, the hub and the power supply.
− Use the patch cable to connect the hub to the Ethernet-PROFIBUS gateway. Connect the hub tothe power supply.
− Connect the PROFIBUS cable and power supply to the Ethernet-PROFIBUS gateway.
1.2 CeSAR slew/blind
− Connect up the PROFIBUS cable and power supply to the wired module.
2. Set the PROFIBUS address
− Set the PROFIBUS address on the coding switch marked "Address" on the Ethernet-PROFIBUSgateway. Then switch the gateway power supply off and on again, because the address becomesoperative only when the power is switched on.

4.2 General information
− Switch power supply off and on again and perform a trial run
4.2 General information
The system is commissioned by setting parameters using the CeCOMM diagnostic program.
4.2.1 Parameters menu
For this purpose, the Parameters menu is called from the main menu or another display screen with the "P"key. The Parameters menu contains an overview of the parameter groups that can be displayed in shortform, page-by-page via the keys "1", "2", "3", etc.
An overview of all the functions which can be executed from the Parameters menu is also provided.
Parameters which are not set to their defaults are identified by a "+".
Only values in the range between the fixed minimum and maximum values can be entered for the parameter.If acceleration parameters are set to lower than 20, they will be interpreted as times and converted to thecorresponding parameter values.
Note
Each changed parameter takes effect immediately, but is not stored permanently. After confirmation with"OK", changes to parameter values should be permanently stored with "S" (Save all sets of parametersand fixed ranges). "S" always saves all parameter sets.
4.2.2 Parameter sets
Four parameter sets are provided. They are stored as a text file in directory /FlashFx/ on the flash EPROM.
The files are named Par0.txt, Par1.txt, Par2.txt and Par3.txt. If no parameter files are available at the start of the program or they are faulty, all parameters are set to their default values.
NOTICE
he parameter sets are numbered 1 to 4 in the CeCOMM diagnostic program. Therefore, file Par0.txtcontains parameter set 1 and Par3.txt parameter set 4.
If a parameter exceeds the specified limits when it is loaded, an error message is generated and the value of the relevant parameter is set to the default value.
The current parameter set is specified using the general command bits.
All parameter sets can be edited independently of the current command bits.
4.2.3 Switching parameter sets
NoteThe control response or system configurations can be changed by switching the parameter sets. Inconjunction with control elements, the crane operator can select a desired configuration.
The parameter "Parameter set locked during travel“ can be used to prevent the switching of parameter setsduring travel.
When the parameters of one set are copied to another set, it is possible to choose whether to copy allparameters or only the parameters from P60 onwards.

4.3.1 Setting the access code
The access code sets the user level and determines the visibility of individual parameters. The access codeis stored in parameter P100.
Note
Only those parameters are displayed that correspond to the setting of parameter P100 (= access code).
Parameter P100 (= access code) must be set to "Service engineer" for commissioning.
The following settings are available:
• 0 = Any user
•1 = Commissioning engineer
• 2 = Service engineer or specially trained commissioning personnel
4.3.2 Setting the language
All screen displays in the diagnostic program are stored in language files on the camera.
The language is set in the diagnostic program "CeCOMM" via the menu "Options/Language" and saved inparameter P110. German and English are available.
Alternatively the language parameter P110 can be changed via the Parameters menu. The appropriatelanguage file is then automatically opened and read. The screen displays are updated.
4.3.3 Master and slave cameras for CeSAR slew
With the CeSAR slew variant of the system, the camera casing contains two cameras in order to increase thevertical field of vision for reflector detection. In this case, one camera is the master and the other camera theslave. The only task of the slave camera is to detect load sway and send the swing angle to the master if thereflector is outside the field of vision of the master.
The sections in Chapter 4 refer to the master camera and must be taken into account in relation to the master during commissioning. Nevertheless, certain commissioning steps still have to be performed for the slavecamera once the master camera has been commissioned. The commissioning engineer must first establisha connection to the slave camera via the terminal (CeCOMM) and set parameter P67 to "2".
The parameters P65, P72 and P73 must be set to the same values as the equivalent parameters of themaster camera.
The instructions from the chapter below must then be followed. Finally, commissioning step a (wippen.txt),two to four and six, must be performed.

4.3.4 Checking the interface
PLC - CeSAR slew
The communication link between the PLC and the sway control system must first be checked with theCeCOMM diagnostic program.
This includes checking whether data is being properly exchanged and whether the correct data formats andcontent are being used.
The display screen "Profibus Interface" (opened with key "2") shows the current input and output data of the sway control system. The data must first be checked for correctness.
Prerequisite for all other steps is correct incrementation of the send and receive counters in displayscreen 2. This means that the camera is receiving and sending data message frames.
Fig. 4-1: Monitor function, "PROFIBUS – Interface" display screen
The "CeSAR slew – Status of travel axes" display screen is opened with key "3" (Fig. 4-2). The command
and status signals are displayed here. They should also be checked for correct assignment before the nextcommissioning step is taken. The color differences in the display of the actual values show which values or states are OK or active (green).
Note
Red display indicates an error or stop in the system, "Not released", "Stop", "Off", etc.
No values should be displayed in red in Figures 4-1 and 4-2, as this would indicate an error or a stopcondition in the system ("Not released", "Stop" or "Off function" activated).

Fig. 4-3: Checking the camera image
The current camera image should have the following characteristics:
• The reflector must be correctly focused and well illuminated. (The image might still be too brightor dark before the system is commissioned – please refer to Chapter 4.6 (Camera operation) for
information on how to optimize the image)• With a slewing motion, the reflector moves horizontally through the image during hoisting. In
this case, it must be as close as possible to the vertical center of the image.
WARNING
Execution of this function causes very long cycle times in the camera and thus to a breakdown incommunication. For this reason, images should be read in (transferred) for diagnostic purposes only whenhe crane is stationary.
Proper functioning of the camera measurement system can be checked by means of diagnostic monitor four of the terminal. A screenshot of this monitor is shown below.

Commissioning the sway control system
4.5 Commissioning steps in the Commissioning menu
4.5.1 Commissioning step 1
In the first commissioning step, the system will request input of the settings for the following parameters:
P73 Double-jib (0) single-jib crane (1) with hydraulic drive (2)
The parameter must be set according to the crane type. On cranes with a hydraulic drive, a speed offset isactive for the hydraulic drive which is calibrated in commissioning step 9.
Default: 0
Single-jib crane
A single-jib crane is a light-weight crane andis thus ideal for use in areas with limited load-bearing capacity, e.g. narrow quays and andlight-weight craneways. The single-jib cranereveals its full potential when it is used tohandle bulk materials, especially heavy or extremely heavy loads.
Double-jib crane
Double-jib cranes are also used, for example, tohandle bulk materials. By virtue of its designprinciple, the double-jib crane offers the advantageof short load paths and pendulum lengths, but it alsooffers a second decisive benefit: The load handlingmovement is essentially controlled by the luffingmotion, i.e. the slewing motion is of secondaryimportance. The effects of braking and accelerationhave no impact on performance.
Hydraulic system:
The non-rotatory motion of the boom is controlled by a hydraulic luffing gear.
P67 Single (0)/Master (1)/Slave (2) cameraThis parameter must be set to 0 for the CeSAR blind variant. When the camera-based variant is used(CeSAR slew, system uses two cameras), the parameter must be set to 1 for the master camera and 2 for the slave camera.Default: 0
P109 Normalization setpoint and control speed
The parameter contains the normalizing factor for all speeds that are transferred via the fieldbus. If theparameter is set to 28,000, for example, then a setpoint speed of –14,000 corresponds to half the negativemaximum speed (P1 or P21) of the corresponding axis.

4.5 Commissioning steps in the Commissioning menu
Default: 32.767
These parameters are specified by the crane manufacturer or derived from their specifications.
P1 Maximum control speed of luffing gear
Speed limit value in mm/s. Notice: The set value corresponds to the maximum attainable speed of the drive(hydraulic cylinder, toothed rack etc. ) and not the speed of the boom.
The maximum control speed corresponds to the maximum attainable speed of the drive axis. It influences theamplitude of the oscillation model and must therefore be set precisely.
Default: 500 mm/s
P2 Acceleration without sway control
When the sway control system is deactivated, the drive accelerates and decelerates with the set acceleration
value. The value is applied as a minimum deceleration rate when the prelimit switch range is reached. Theparameter is thus applied for two scenarios in the sway control system, i.e. travel without sway control andtravel in the prelimit switch range. If different acceleration rates need to be used for these two situations, thena parameter set switchover will be required.
Default: 150 mm/s²
P3 Setpoint acceleration of the boom
The setpoint acceleration is an internal acceleration variable in mm/s². It is operative in all basic operatingmodes, during acceleration and deceleration. Input values less than 20 are interpreted as a ramp time. Setmanually according to manufacturer or customer specifications. The value should correspond to approx. 75%of the maximum acceleration (P4).
Default: 150 mm/s²
P4 Maximum acceleration of boom
Acceleration limit in mm/s². The set value corresponds to the maximum boom acceleration/deceleration.Input values less than 20 are interpreted as a ramp time.
The maximum acceleration setting limits the rate of acceleration of the output signal of the sway controlsystem. It should be set to the same or a smaller value than the converter acceleration limit.
Default: 250 mm/s²
P0 Positioning speed luffing gear
This value (in mm/s) corresponds to the maximum speed of the boom in positioning mode. P0 is alwayslimited internally to 95% of the currently possible maximum boom speed. The boom speed is determined by
file Wippen.txt Geometry. The positioning speed is the maximum setpoint speed specified for automaticpositioning. Depending on control processes, the actual speed can be less or greater, but never greater thanthe maximum control speed.
Default: 450 mm/s

4.5 Commissioning steps in the Commissioning menu
P10 Deceleration gain, luffing gear
Deceleration gain or reduction factor. The deceleration rate is calculated on the basis of P3*P10, or
P3*P10*P113 for plugging. These values are also limited by the maximum control value P4.P10 has no effect in positioning mode.
Default: 1
P20 Positioning speed slewing gear
This value (in cgr/s) corresponds to the maximum speed in positioning mode. In order to allow a slightovershoot, a value corresponding to 90% of the maximum control speed should be set.
Default: 450 cgr/s
P21 Maximum control speed, slewing gear
Speed limit in cgr/s. The set value corresponds to the maximum attainable speed.
Default: 500 cgr/s
Note
After the user has confirmed the setting for parameter P21, the system asks whether P20, P22, P23, P24and P32 should be updated. Updating is meaningful only if the speeds and acceleration rates dependentupon P21 have already been entered and only P21 needs to be adjusted again. With this "update"process, parameters P20, P22, P23, P24 and P32 are altered in equal proportion to P21.
P22 Acceleration without sway control
When the sway control system is deactivated, the drive accelerates and decelerates with the set accelerationvalue. The value is applied as a minimum deceleration rate when the prelimit switch range is reached. The
parameter is thus applied for two scenarios in the sway control system, i.e. travel without sway control andtravel in the prelimit switch range. If different acceleration rates need to be used for these two situations, thena parameter set switchover will be required.
Default: 150 cgr/s²
P23 Setpoint acceleration rate, slewing gear (inner circle)
The setpoint acceleration is an internal acceleration quantity in cgr/s² for operation with active sway control(input bit "AS_ON").
In positioning mode, the value of P23 is always applied for the slewing gear. In speed control mode, thesetpoint acceleration rate depends on the current position of the luffing gear. (See Section 1.7.1 anddescription of P32 for details.)
Default: 150 cgr/s²
P32 Setpoint acceleration rate, slewing gear (outer circle)
The setpoint acceleration is an internal acceleration quantity in cgr/s² for operation with active sway control(input bit "AS_ON").
P32 is relevant only in speed control mode. (See Section 1.7.1 and description of P23 for details.)
Default: 75 cgr/s²

value should be 50 to 100% higher than the setpoint acceleration.Default: 250 cgr/s²
P30 Deceleration gain, slewing gear
Deceleration gain or reduction factor. The deceleration rate is calculated from the product of P30 and theinterpolated slewing acceleration value (see description of P23 and P32). The second factor corresponds toP30*P114 for plugging. These values are also limited by the maximum control value P24. P10 has no effectin positioning mode.
Default: 1
P92 Luffing gear position for automatic inward luffing
This luffing gear position is approached first in automatic positioning mode. Outward luffing toward the targetposition of the luffing gear commences shortly before the slewing gear reaches its target position. Theparameter should be set to the last luffing gear position at which the slewing speed has not yet started todecrease.

4.5.2 Checking the file "wippen.txt" (commissioning step a)
Section 3.6 describes how the file "wippen.txt" (which must be set up by the user) should be structured. Incommissioning step a, the user should check whether the system has correctly identified the file. Thiscommissioning step should be carried out before the crane performs any movement. When the step isselected, the sway control system loads the "wippen.txt" file currently stored in folder FlashFx on the camera.There are three possible scenarios after selection of this step.

4.5 Commissioning steps in the Commissioning menu
In the first scenario, a read-in error has occurred and a corresponding message is displayed when the step isselected. Furthermore, error signal E7 is set and the luffing gear cannot be moved.
In the second scenario, a table has been read in and the commissioning screen displays the table values. Inthis case, the user must check whether the numbers are correct.
In the third scenario, the "wippen.txt" file contains geometry parameters. These are displayed on the screenand the user must check whether they are correct. Another screen is displayed containing the tablecomputed internally from the geometry parameters and the content of this table must also be checked by theuser.
At the end of the step, "n" can be entered in order to return to the beginning of the step. When this is done,the "wippen.txt" file currently stored on the camera is loaded. If the user loads a new "wippen.txt" file to thecamera before entering "n", this new file will be read in. By pressing any of the other keys, it is possible toreturn to the commissioning menu.
4.5.3 Determining the reflector type (commissioning step 2)
From the viewpoint of the camera, the reflector can be aligned in two ways.
P62=1 P62=0
reflector 1 reflector 2
Fig. 4-6: Reflector alignment
The algorithm searches for the two alignments and shows the result.
Only one reflector alignment may be detected during this commissioning step.
Note
For the purpose of the alignment check, the distance between the reflector and the camera should lie inthe range 5 m to 10 m.
Precondition for accurate calculation of the value of P70: The reflector must be in the center of the image,it must be correctly focused, and must not move (it must be absolutely still). After completing thecommissioning step, the user should always check the "distance" display in Monitor 4 for the correctdistance. If there is a significant deviation, the commissioning step must be repeated.
When the reflector type is determined on a system with master and slave cameras, the reflector must be
situated exclusively in the field of vision of the relevant camera.
If both alignments are detected, this can have the following causes:
Two reflectors are present in the field of vision of the camera.
A light-dark combination in the field of vision has been incorrectly identified as a reflector. In this case, theparameter P62 must be varied manually and the measurement result in display 4 compared with the positionof the reflector.
The reflector is detected by both the master and slave cameras.
If no reflector is detected, this can have the following causes:
The camera is not aligned correctly. The reflector is not in the field of vision.

Commissioning the sway control system
4.5 Commissioning steps in the Commissioning menu
The ambient light is too bright or too weak. The parameters for gain and offset (P60 and P61) can betemporarily set to zero. The camera then automatically sets the gain and the offset to the brightness of theentire image. After successful completion of the commissioning step, the parameters must be reset to theoriginal or required values.
The window size (parameter P63) is set to values that are too large or too small. P63 should be set to "11" per default.
After completion of the commissioning step, the current distortion of the reflector is also stored (P70). Thisquantity is important for measuring the distance correctly.
Note
On completion of commissioning step 2, it is possible that the value calculated for P70 will not be storedcorrectly even though the save command was selected at the end of the step. The user can checkwhether the value has been stored by looking in the Parameters menu to see whether the value displayedfor P70 is the same as the value previously displayed on the screen.
4.5.4 Determining the minimum window size (commissioning step 3)
To obtain highly reliable measurements, the P63 parameter can be used to set the smallest size of thereflector in the image.
The image will then always be searched for a reflector with this minimum size and all similar smaller-sizedpatterns will be ignored.
Parameter P63 is set to values of between 1 and 10 to program a fixed minimum window size. A setting of 1means that the reflector is very small in the image and a setting of 10 that it is very large.
Automatic adaptation of the minimum window size is activated when P63 is set to a value of between 11 and20. This function works provided that the reflector has been detected. The setting values 11 to 20 (which
correspond to 1 to 10) are otherwise applied as the minimum window size.
Fig. 4-7: Determining the minimum window size
Note
For semi-automatic determination of the size, the reflector (the load carrying device) must be luffedoutward as far as possible.
The diagnostic system then checks the size of the detected reflector and suggests an appropriate factor.
4.5.5 Setting the alignment of the camera (commissioning step 4)
In this commissioning step, the assignment between the directions of motion and camera orientation iscalculated (P66).
Note
After the commissioning step has been started, the load hook must be lifted while the load is not swinging.
The diagnostic system detects the direction of motion of the reflector in the camera image and uses this todetermine the camera orientation in relation to the crane axes.

4.5.6 Calibrating the hoisting height (commissioning step 5)
When the hoisting height is calibrated, the gain and offset are determined for the conversion of thetransmitted hoisting height to an effective pendulum length with correct sign and absolute value.
The calibration is performed with two sway measurements at different heights. The respective effective ropelengths and conversion parameters are determined from these movements.
4.5.7 Calibrating the camera measurement (commissioning step 6)
NOTICE
Calibration is possible only when no camera measuring error is present.
To calibrate the camera, the reflector must be moved to 4 specific positions. The commissioning engineer must confirm each position. The position sequence (P1 – P2 – P3 – P4) is illustrated in the following diagram:

4.5.10 Saving parameters (commissioning step 0)
All parameter sets are saved.
The commissioning parameters can be copied to the other parameter sets in the Parameters menu.
4.5.11 Calibrating the hydraulic luffing drive (commissioning step 9)
This step can be performed in order to determine the speed-dependent non-linear behavior of a hydraulicluffing drive. After successful completion of the step, the system will compensate the non-linear behavior.
The luffing gear must fulfill one important requirement in order to ensure successful completion of the step. Itmust be capable of reaching the speed specified by P1 in both directions (cylinder is retracted/extended bydrive). The commissioning engineer may need to adapt P1 for this purpose.
The commissioning step comprises two phases. During the first phase, the luffing gear of the crane must bemoved backward and forward by maximum deflection of the joy stick. During this process, the control speedof the luffing gear is incremented (in 2% steps) by the software and held for approximately 2 seconds in eachstep. The quotient of the actual speed at the end of each step and the currently applied control speed is thencalculated. The commissioning screen gradually displays the values as they are calculated. At the end of the
phase, a table containing the speed steps (-50 -> retract cylinder with 100% of P1, +49 -> extend cylinder with 98% of P1) and the quotients has been generated.
On the last line of the terminal monitor, the current values for normalized control speed (normalization P109),speed steps (between -100 and +100, 2% steps), control speed and actual speed are displayed in eachcase. If teach-in is aborted during the first phase of the commissioning step, any missing values are filledusing the corresponding data currently stored on the camera.
In the second phase, the user can modify individual values manually. It is thus possible, for example, tomodify any seemingly implausible anomalous values.
NOTICE
Unsuitable values in file Hydraulik.txt can result in false control speeds.
At the end of the step, the table of quotients can be stored in file "Hydraulik.txt". (NOTICE! The first column of the file Hydraulik.txt does not contain the indices -50 to 49, but numbers 0 to 99 instead.) Once the table hasbeen stored, the sway control system will apply its content in operation to compensate the non-linearities of the luffing gear hydraulic system.

4.6 Checking and fine adjustment of the camera
Note
To ensure correct hydraulic system calibration, the resolution of the luffing gear position must not exceed
1cm per increment.
Note
While commissioning step 9 is in progress, traces cannot be recorded with the CeCOMM tool.
4.6 Checking and fine adjustment of the camera
The following parameters can be set manually from the Parameters menu of the diagnostic program:
Most of the parameters listed below will have been set during the preceding commissioning steps, or arepreset in the shipped state, and should only be changed where necessary.
Selecting passive or active reflector
The type of reflector (passive or active, P72) must be set. The different brightness conditions for activereflectors fitted with LEDs and passive reflectors means the camera uses two different optimizationalgorithms for the brightness control.
Reflector type
The reflector type is determined in commissioning step 2 (P62).
If no reflector is found even though it is situated within the field of vision, the set window size (P63) must alsobe checked.
LensIf the accuracy is not adequate, a lens with a longer focal length can be used. This, however, reduces themaximum measurable swing angle.
The focal length of the lens is preset, but the setting can be changed if necessary in parameter P78.
Brightness
The software controls the reflector brightness depending on the ambient light when parameters P60 – Videoinput gain and P61 – Video input offset are set accordingly.
The default values mean:
Gain = 64 The gain is adjusted proportional to the offset.
Offset = 256 The offset value is increased and decreased between 1 and 255 until a reflector is found. Thereflector brightness is then regulated to a constant value.
Note
The current offset and gain values are shown in Display 4 during camera diagnostics.
Window size
The camera searches for a reflector of a specific size (commissioning step 3 in Chapter 4.5.4). When awindow size of 1 is selected, the camera searches for a reflector of 12 x 12 pixels in size. When a windowsize of 10 is selected, the reflector must be 66 x 66 pixels in size in the image. By comparison: The entireimage is 640 x 480 pixels in size.

Commissioning the sway control system
4.6 Checking and fine adjustment of the camera
Note
To prevent incorrect measurements, the set window size should be as large as possible.
However, if the set window size is larger than the reflector image, the camera will not find the reflector at all.For this reason, changes to parameter settings should be checked at the maximum distance betweencamera and reflector.
Values larger than 10 activate the automatic window size control function. If no reflector is found, "windowsize = parameter value – 10" will be set. If the reflector has been found and it lies completely within thecamera image, the window size will be automatically adapted to the size of the reflector (1..10).
Note
The current window size is shown in Display 4.
Limitation of search area
If the camera incorrectly identifies a reflector in an incorrect image area, the search area for the global searchshould be limited.
The search area limits remain valid only while the camera is unable to find a reflector (global search). Oncethe reflector has been found, the camera searches only in the immediate vicinity of the last position (localsearch).
Using parameters (P76, P77) it is possible to reduce the size of the search area by up to 90%, starting fromthe outer boundaries.
Injection of camera measuring signal
The settings of parameters P19/39 "Gain of camera measuring signal for luffing/slewing gear" can beadjusted to determine the extent to which the internal oscillation model will be influenced by camerameasurements. The camera measurement has no effect when the setting is zero.
If internal drive delays of significant duration occur, it can be useful to deactivate injection of camerameasurements using P82 as of a certain hoisting height (see Description of Parameters for further details).
Note
The luffing gear and slewing gear are coupled in the internal oscillation model. For this reason, when thecamera is active and P39 equals 0 and P19 does not equal zero, the camera measurement of the luffinggear will also influence the sway neutralization motion of the slewing gear. When the assignments of P19and P39 are reversed, the response of the oscillation model is also reversed. Both these parametersshould normally be set either to zero or to a value other than zero.
Measuring reliability
Several parameters can be used to influence measuring reliability.
The algorithms first use fast search functions to find a reflector in the image and determine a recognitionreliability. Parameter P64 "Reflector recognition limit" is used to specify a minimum limit as of which areflector can be deemed to have been reliably recognized. When the reflector is situated in heavy shadow,this value should not exceed 650 (65%).
The subsequent size measurement then returns a high reliability for the presence of a reflector in the image.Up to 16 characteristics are checked for this purpose. Parameter P71 ("Measuring reliability of the camera")can be used to specify the number of characteristics to be used. If more than 10 characteristics are specifiedto be checked, a reflector will be used only when the reflector size was determined using the characteristics.This means P71 > 10 achieves a very high measuring reliability.

4.7 Checking and fine adjustment of the sway control system
Note
Setting very low values for P64 and P71 can cause reflector recognition errors. This can in turn result inabrupt speed changes in the oscillation model and have a negative impact on sway neutralization.
4.7 Checking and fine adjustment of the sway control system
The following parameters can be set manually (if this has not already been done in commissioning step 1)from the Parameters menu in the diagnostic program:
Specifying the hoisting height range
In order to determine the limits for hoisting height parameters P85/P86 and P90/P91, proceed as follows:
Make sure that the hoisting height has been calibrated correctly
Move the hoisting gear across the entire traversing range and measure the minimum and maximum
pendulum lengths (values are displayed in screen 1 "Kinematics" in CeComm)
These limit values (plus a safety reserve in both directions) are entered in parameters P85/P86
If for any special reason you want the sway control system to be deactivated at a specific hoisting height, thisresponse can be set with parameters P90/P91, otherwise set P90 = P85 and P91 = P86.
The parameters "Upper and lower sway control limits" (P90, P91) are used to specify the hoisting heightrange in which the "Sway control" function is active.

The range for the permissible pendulum length P85 / P86 must always be larger or equal to the range for hoisting-height-dependent deactivation of the sway control system P90/P91, i.e. P85 <= P90 < P91 <=P86.
Parameters P85, P86, P90 and P91 are taken into account in error messages E4 and E5 (see Section 5.2.2).
Compensating load carrying devices
If different load carrying devices are used, this information must be passed to the control software as thecenter of gravity and/or the pendulum length changes.
The following parameters are used to adapt the system to load conditions:
a) Weight of load carrying device P89
b) Analog hoisting distance correction P88
c) Digital hoisting distance correction P87

4.8 Commissioning the positioning system
Note
In certain constellations, the load offset might trigger error message E4, but not E5.
Setting the permissible residual sway
The parameters for residual sway (P103, P104) should not be set lower than required. Values that are toolow can result in swaying after stopping because of dead times.
Setting the sway control factor
A sway control factor (P15, P16, P35, P36) can be set for each travel axis for manual operation (separatevalues for acceleration and deceleration). Values greater than 1.4 result in aperiodic transient responses,values less than 1.4 to overshoot. Sway control factors in the range from 1 to 1.2 represent a compromise
between short rise time and slight overshoot. The difference between the sway control factors for acceleration and deceleration should not be too large, as the control signal can otherwise change abruptlyduring the transition to the deceleration phase.
Only the values of P15 and P35 are relevant in positioning mode. No distinction is made betweenacceleration and deceleration.
Defining the minimum speed and minimum time
The sway control system is not activated until the minimum speed (P105) and minimum time (P106) havebeen reached. It is recommended that both parameters be left at zero. If the activation conditions are nolonger fulfilled, the sway control system is deactivated after the deactivation delay time (P107) has expired.
Setting the starting delay of the drives
The starting delay of the frequency converter after opening of the brake can be set for each axis ( P120,P121).
4.8 Commissioning the positioning system
4.8.1 Calibrating the position value
In order to commission an automatic positioning system, the position values must be calibrated.

• s1 Distance value sent by the PLC at position 1
• s2 Distance value sent by the PLC at position 2This information can be used by the diagnostic program "CeCOMM" (menu "Calculations/Positionparameters") to compute the conversion parameters "resolution" (rise) and "offset".
Resolution and offset must be entered for specific axes in the corresponding parameters.
Resolution of position sensor (P5, P25)
The resolution or maximum control speed of the relevant drive axis must be set such that the displayedactual speed corresponds to the control speed in travel at constant speed in manual operation.

Offset of position sensor (P6, P26)
The offset should be set such that the internal position values are always positive.
4.8.2 Set position controllers and sway control factors
The position controllers must be set as shown in the following sequence:
Set position controllers (P14, P34) to zero and start positioning over a long distance
The setpoint and target positions must be virtually identical at the end. Slight differences result through thedeactivated position controller.
Greater deviations might be caused by a maximum control speed error or limits in the drive system. (In order to localize the error, the sway control system can be deactivated by setting the sway control factors to zero.)
Setting the position controllers and sway control factors to default valuesThe sway control factors must be set so as to obtain slight overshoot at the target position (default value).This setting produces short rise times in the sway control system.
The position controller outputs must be slowly increased in 0.1 increments and the behavior compared after each increase by means of a positioning movement (record chart).
The value should not normally exceed 0.5.
The value must be reduced if the speed curve exhibits oscillations or oscillations occur at the target positionas a result of the position controller.
Excessively high setting values can cause swaying movements!
Note
High position controller settings can result in residual sway after positioning.
The value must be reduced when connection of the speed controller causes an oscillating speed curve andan overshoot at the target position.
Note
An overshoot at the target position often results not from a large position controller value but rather froman incorrectly set limit speed. Before the position controller setting is reduced, therefore, another checkshould be performed in travel at constant speed and in controlled operation (position controller set to zeroor manual operation) whether the actual speed is approximately equal to the setpoint speed.
The position control function can be optimized by adaptation of parameters P118 and P119.
4.8.3 Other settings
The following parameters can be set manually:
Positioning accuracy (P9, P29)
The set positioning accuracy should be as small as necessary and only affects the "Positioning complete"message. Positioning continues while the mode and the travel signal remain set.
Following error (P122, P123)
The following error is the difference between the calculated position and actual position of the crane. An error message is triggered when the tolerance is exceeded.

5.1 Parameter list
5.1.1 Parameters for luffing gear
P0 Positioning speed luffing gear This value (in mm/s) corresponds to the maximum speed of the boom in positioning mode. P0 is alwayslimited internally to 95% of the currently possible maximum boom speed. The boom speed is determined byfile Wippen.txt Geometry.
Default: 450 mm/s
P1 Maximum control speed of luffing gear
Speed limit value in mm/s. Notice: The set value corresponds to the maximum attainable speed of the drive(hydraulic cylinder, toothed rack etc. ) and not the speed of the boom.
Default: 500 mm/s
P2 Acceleration without sway controlWhen the sway control system is deactivated, the drive accelerates and decelerates with the set accelerationvalue. The value is applied as a minimum deceleration rate when the prelimit switch range is reached. Theparameter is thus applied for two scenarios in the sway control system, i.e. travel without sway control andtravel in the prelimit switch range. If different acceleration rates need to be used for these two situations, thena parameter set switchover will be required.
Default: 150 mm/s²
P3 Setpoint acceleration of boom
The setpoint acceleration is an internal acceleration variable in mm/s². It is operative in all basicoperating modes, during acceleration and deceleration. Input values less than 20 are interpreted as aramp time. Set manually according to manufacturer or customer specifications. The value should
correspond to approx. 75% of the maximum acceleration (P4). (see Chapter 3.7)Default: 150 mm/s²
P4 Maximum acceleration of boom
Acceleration limit in mm/s². The set value corresponds to the maximum boomacceleration/deceleration. Input values less than 20 are interpreted as a ramp time.

P82 Upper limit for camera measurement
The camera measurement is deactivated for pendulum lengths shorter than this value. This can be a useful
response in the following situations: If internal drive delays occur as a result of conversion of the controlvalues supplied by the CeSAR system, a difference can develop in the phase between the internal oscillationmodel and the camera measurement.

Default: 0
P118 Time constant current rise luffing gear
The current rise and therefore the change in acceleration over time are often limited by the converter. In order to take this delay into account when activating the oscillation model and the position control, a first-order delay element has been provided, whose time constant is set with this parameter. If the value is less than 1,the delay element is deactivated.
Default: 0 ms
Note
This parameter can also be used to compensate runtime delays in the crane control system (PLC).
P119 Time constant current rise, slewing gear
The current rise and therefore the change in acceleration over time are often limited by the converter. In order to take this delay into account when activating the oscillation model and the position control, a first-order delay element has been provided, whose time constant is set with this parameter. If the value is less than 1,the delay element is deactivated.
Default: 0 ms
Note
This parameter can also be used to compensate runtime delays in the crane control system (PLC).
P120 ON delay, luffing gear drive
ON delay of the converter after opening of the brakes. If the value is less than 1 and greater or equal to 0, thedelay element is deactivated. With a single-jib crane with hydraulic system (P73>=1), a setting of -1 will mean
that the ON delay is automatically detected in travel according to polar coordinates on the basis of the luffingspeed.
P120 influences the following error in positioning mode. The larger the value (and real deceleration of thedrive), the higher the following error will be. In order to prevent the CeSAR system from issuing following error messages, P120 can either be reduced and the procedure described in Section 3.5.4 applied(recommended), or P122 (following error luffing gear) can be increased.

5.2 Error messages
5.2.1 General
WARNING
Situations can develop while the crane is moving which cause the control value issued by the CeSARsystem to be abruptly reset to zero. In this case, the braking ramps are determined by the set converter ramps (Chapter 3.9.2). The sway control system ceases to function.
This type of scenario can occur, for example, if the parameter settings for positioning accuracy, residualsway and zero speed signal are high and the sway control system generates the "Positioning complete"signal internally while the control speed is still high.
Another typical scenario is when the PLC resets the travel signal while the crane is moving.
WARNING
The PLC programmer is obliged to evaluate the error messages issued by the electronic sway control
system. The control values from the sway control system must not be utilized when an error is active. Thedrive control system must be controlled exclusively via the PLC.
Each error has a number, a title, an error description and remedy information.
The errors have one of three different characteristics:
Error ÆReaction needed, deactivate sway control system
Warning Conditional reaction, sway control system need not be deactivatedÆ
Note Æ Status and diagnostic function
Errors that are transferred to the PLC, are identified by an error bit.

Parameter and Error List
5.2 Error messages
Note
If this error is not processed in the PLC and occurs while the crane is in motion, the slewing motion
towards the target position will continue. However, the luffing gear cancels the positioning operation, butcontinues to perform the compensating movements required to neutralize the radial swaying motionsgenerated by the slewing gear.
A different response can be obtained by entering the corresponding input bits of the sway control systeminto the PLC. For example, if it is desired that the luffing and slewing gear stop moving with active swaycontrol, the bit "Controlled stop" must be set for both of them.
E4 Invalid hoisting gear position

Camera is not receiving any message framesalthough the PLC is receiving data. Error message "Fieldbus error". The status LEDsof the gateway and camera connections areilluminated on the hub. However, only thetransmit LED of the camera is flashing.
Check the hardware configuration.
The data must not be transferred as consistent datato the peripheral output!
The counter in the send data message header mustbe incremented with each new cycle. Thisincrementation triggers the transmission of Ethernetmessage frames through the gateway.
Crane does not settle after completion of thetravel motion.
Check minimum frequency and ramp-up time of theconverter.
The actual pendulum length differs greatly from theinternally calculated effective pendulum length(display 1).
Calibrate the hoisting height (commissioning step 5)
Sway control system initiates swayingmovements.
Check acceleration and deceleration ramps of theconverter, delete any roundings and check thecontrol parameters of the converter.
Setting the alignment of the camera (commissioningstep 4)
Crane moves a short distance on its own for no reason.
Camera loses the reflector and for a short time findsobjects in the vicinity similar to reflectors. Determine
the minimum window size (commissioning step 3)Change low-pass frequency factor (1), restrict thesearch area of the camera, increase the contrast.
Trim oscillations occur with a higher frequency than the swaying movement.
Activation of the low-pass filter for the appropriatedrive axis (typical value: 1) and reduction of thecamera injection (typical value: 0.015)
Residual swaying movements are always or occasionally too large.
Check ramps and speed controller of the converter.

Maintenance 6
6.1 Reflector maintenance
The reflector must be cleaned regularly depending on the dust content of the environment. If the dust contentis low, it is sufficient to inspect/clean the reflector once per year. If the dust content is high, however, the
reflector must be cleaned at 4-6 weekly intervals. All dirt and paint residues must be removed.Solvents must not be used to clean the reflector.
The reflector must be checked for secure mounting as part of the regular crane inspection.
6.2 Camera maintenance
The glass screen on the front of the camera's protective casing must be checked at the same intervals as thereflector and cleaned if necessary. The camera must also be checked for secure mounting.
