PREFACE

This manual describes the characterization phase of the 10 Series CNC system through use of the AMP (Adjustable Machine Parameters) and Servo Monitor utilities. AMP allows the operator to enter all the necessary parameters and information to configure the system and the various machining processes. The Servo Monitor allows the operator to perform a tuning of the system in order to achieve optimum performance. The manual is intended for the operator that has in charge the system characterization after installation.

GENERAL CONCEPTS

This chapter provides a glossary of the terms used in the present AMP Configuration Guide. For users who are not familiar with NC technology it may serve as an introduction to the philosophy underlying system operation. Users with extensive NC experience can use it as a source of lexical reference. Special attention has been devoted to the classification of the axes and to the description of the characteristics of the various types. Users already familiar with numeric control machines may use this chapter as a terminology reference.

SYSTEM ARCHITECTUREThe architecture of 10 Series CNC can be broken down into four partitions, each of which controls a specific set of features.

The major function of each partition is as follows: Numerical Control Utilities I I/O Interface Human Interface Includes the part program interpreter, the axes interpolator and the process manager for machining centers. ncludes a series of text-only and graphics packages that can be used by the end user, the OEM or the technical assistance. Controls the execution of the machine tool/control interface code that has been developed by the OEM. Controls all the data input and display operations and the man/machine interface.

CLASSIFICATION OF THE MACHINE AXES10 Series CNC can control the following types of axes: Coordinated axes These are physical axes that move in coordination with each other. Each 10 Series CNC AMP process can move 9 simultaneous axes and up to 9 coordinated axes. These are physical axes that are not requested to move in coordination with each other. This is the tool-holder spindle. 10 Series CNC can associate one spindle with each process.

Auxiliary axes

Spindle axis

The axes can also be classified according to the type of move that they must carry out: linear axis rotary axis split axis It is an axis moving on a rectilinear trajectory It is a coordinated axis programmable in degrees. It is a physical axis coupled to a pair of motors for synchronized motion. It is an axis whose moves are dependent on the moves of the master axis to which it is coupled. It is a coordinated axis that must be programmed and displayed with a 2 coefficient.

dual axis

diameter axis

They are also classified as a function of type of interface with the drive. In this manual we distinguish between analog and digital axes according to the following criteria: Analog axes The axes in this class are (coordinated, auxiliary and spindle) axes whose interface with the drive is an analog homing signal. Axes managed by boards with D/A converters and Bridge OS-Wire devices are part of this class. (Coordinated, auxiliary and spindle) axes whose interface with the drive system is a digital homing signal, and for which communications are performed through high level protocols. This class includes the OS-Wire axes connected to OS3 drives (OSAI protocol), D.S.I. (digital Standard Interface) axes and the axes with Mechatrolink interface.

Digital axes


1-3


SERVO LOOP10 Series CNC permits to define the algorithms that are used for servo loop control of each axis. Such algorithms are based on three configurable constants, Kc, Kv and Kcs. 10 Series CNC uses these constants in the following formula: Vout = (Le * Kv + Vff) * Kc Where: Vout output voltage is the voltage output by the Digital/Analog converter is the variance between the programmed axis position requested by the control and the actual position measured by the position transducer is the position loop gain velocity feed forward is a velocity value that is proportional to the programmed axis feedrate.

Le

lagging error

Kv

servo loop gain

Vff

The units of measure for the constants are: Le [mm], Kv [1/s], Vff [mm/s] (Le * Kv + Vff) represents a velocity. Therefore, Kc is a velocity-to-voltage conversion factor . The control applies the following internal formula: Vout = Le' * K + Vff * Kc Where: Le' Vff K is the lagging error expressed in "encoder pulses" is a function of the interpolation clock is the result of multiplying Kc by Kv

K and Kc are calculated using parameters established in the system configuration. The formulas are: Kc = Vm*60 60000 8192 * * Fm Cki 10

K=

Vm*60 Pm 8192 * * * (Kv * 16.66666666...) Fm Pe 10

For the spindle, the formula is: Kcs = Where: Vm = maximum voltage Fm = maximum velocity Pm = mechanical pitch Pe = electrical pitch Cki = interpolator clock [ms] 8192 is the number of possible output levels for the D/A converter 10 is the maximum positive or negative voltage output of the D/A converter 60000 is the minute-to-millisecond conversion factor. Vm 8192 * Fm 10

Position toleranceThe position tolerance is the threshold within which the axis must position at motion end. If the axis is out of tolerance, the move is not considered terminated. When a move ends, if the position control is active, the system checks that all the axes are in the programmed position and that their lagging error (Le) is smaller than the threshold configured in the "in position band" field. To enhance the positioning accuracy, the "in position band" threshold must remain active during an interval specified in the "in position window" field. If it does not, or if the positioning error is out of tolerance after the interval specified in the "in position time-out", the system generates an emergency condition.

Dead zoneIt is the threshold within which the D/A reference voltage output remains to zero irrespective of the position error. The dead zone must be smaller than the position tolerance.

Travel limitsEach axis moves within the limits of an operating field, which is a function of the characteristics of the machine and can be established by means of physical and/or calculation devices which protect the axis from erroneous operation or loss of control.

overtravel+ end of travel+ operating limit+ zero microswitch

The axis travel limits may be controlled by: positive/negative end of travel microswitches positive/negative end of travel microswitches positive/negative operating limits NOTE: In many applications zero microswitch can be coincident with end of travel.

1-6



The microswitches start operating as soon as the machine is switched on whereas the operating limits, which are based on the axes positions, start operating only after the axes have been homed. The overtravel microswitches are normally connected directly to the power circuitry of the axes. In order to enable the travel microswitches that are connected to the I/O board they must be managed by the logic. Operating limits are managed directly by the control. While the control executes a special cycle, such as tool or pallet change, the operating limits can be disabled or modified by the logic to allow displacements beyond the limits. Operating limits must be disabled/modified with standstill axes.

Homing cycleEach time the system is switched on it is necessary to execute a homing cycle, i.e. to move the axes to the microswitch that is considered as the machine zero. The aim of this operation is to reset the internal counters that measure the axes positions. For analog axes, zero microswitches have to be managed by the foreground logic according to which signal status must be read in the appropriate bits of status words SW03 and SW04 (See PLUS APPLICATION MANUAL). This cycle is referred to as Homing cycle or Axis reference cycle."

I/O RING MODULE

FOREGROUNDSW

The status of signals SW3 and SW4 must be interpreted as follows: 1= microswitch released 0= microswitch closed


1-7


To invert this operation mode it is necessary to write the NOT operator in the logic equations. The homing cycle makes all the requests and signal controls that permit to refer the machine zero to the initial time. As a rule, in OS-Wire digital axes connected to OS3 OSAI drives, microswitches are connected to the drive itself. It is possible to continue using the microswitches managed by machine logic by changing their resetting mode (see below for details). A homing cycle can be broken down into four main steps: 1. Zero switch search During this step the axis makes a linear displacement in search of the zero microswitch. As the contact with the microswitch occurs, the axis decelerates until it comes to a complete stop. 2. Zero switch release n this step the axis reverts the direction of motion and moves until the zero microswitch is released. The return velocity is equal to the configured "home position feed" and cannot be altered by the "feed override". 3. Electric zero search This step starts when the microswitch is released. The system waits for the electrical zero (i.e. marker ) to be read and then stops the axis. 4. Return to electric zero After the system has acquired the coordinates in which the electrical zero was read, the axis is returned to the zero position. If at cycle start the microswitch is already closed, the system will carry out only the last three steps. If the axis is configured with an optical linear scale, the microswitch is assumed to be missing and 1only the last two steps will be carried out: in this case the electrical zero switch search speed will be the one used in manual mode. The homing cycle will be interrupted if the system is reset or put on hold. To resume the cycle a CYCLE START command must be given.

Manual/automatic switch searchThe switch search can be carried out manually or automatically. The "homing cycle type" field permits to define the switch search mode to be used in the homing cycle for each process. Manual switch search The characteristics of the manual switch search cycle to be carried out by the process axes are as follows: 1. prior to starting the cycle the operator must check that the selected direction of motion is compatible with the configured direction. 2. during the first step, i.e. while the axes are moving towards the microswitch, the operator must not release the CYCLE START pushbutton. If the command is to be sent by the logic, this means that no CYCLE STOP command must be given. 3. after the microswitch has been found the homing cycle will be completed even if the CYCLE START pushbutton is released and unless a RESET or HOLD command is given. Automatic switch search The characteristics of the automatic switch search cycle are: 1. the direction of motion is automatically selected by the control. 2. after the homing cycle has been launched, the operator can release the CYCLE START pushbutton. The cycle will be completed unless a RESET or HOLD command is given.

Operating limitsThe operating limits are defined with respect to the machine zero (c) in the AMP.

Measuring cycleThe coordinates read by the axes boards are referred to the machine zero (c).

Coordinate display modes10 Series CNC permits the display of the following axis coordinates: Absolute coordinates Machine coordinates Work coordinates Distance to go Error referred to the machine zero (c) referred to the machine zero (c) and including the origins programmed coordinates difference between programmed and machine coordinates difference between interpolated and real coordinates

The example that follows illustrates an axes calibration sequence. 1. Set the "null offset" and "home position" fields in the AMP to zero. 2. Key in the corrections to the geometrical errors in the AMP. This corrections are based on the mecahnical distances to the physical microswitch. 3. Switch off and reboot the control. 4.

SPLIT AXESA split axis (gantry) is a physical axis coupled to a pair of motors or drives. Split axes are typical of large machines and of machines with special mechanical requirements, such as From the User's standpoint, a split axis is seen as one single axis configured as a Master.

Servo motor 2

The parameters that configure a split axis are: SKEW It is the maximum acceptable disalignment between two physical axes. Two maximum values are configured: the first one (Max Skew Error) is used both during movement for non referred axes and during the marker search; the second (Skew Error) is used for all other movements for referred axes and after the marker search. When the current skew error exceeds the configured value, an emergency condition (Skew Error) occurs. SKEW GAIN permits to specify the skew compensation value.

SKEW

When the split axis is enabled, the system calculates at each sampling the lagging errors of the master (Lem = Lagging Error Master) and the slave (Les = Lagging Error Slave). The misalignement (SKEW) can be calculated as follows:

SKEW = Lem - Les


1-13


The result of multiplying the SKEW value by the SKEW GAIN can be used for calculating new lagging errors with the folllowing formulas: Lem' = Lem + (Skew Gain * (Skew/2 ) )

Les' = Les - (Skew Gain * (Skew/2) ) If these new lagging errors are multiplied by a K constant, the resulting voltages on the D/A converter represent positive and negative skew compensations to be applied to the master and the slave. Such compensation tends to re-align the axes correctly. In case of emergencies (servo, error, skew error ...) and of all operations generating disabling and abling of a couple of split axes, it is necessary to refer the axes again in order to ensure correct application of configured null offset and home position parameters and recuperate the misalignment between the two physical axes that the activation/deactivation condition may have generated.

The figure illustrates how the wiring and/or the mechanical orientation permit to shift the counting direction of the position transducer or the rotation of the motor between the master and the slave. (T=transducer, M=motor)

With dual axes, only the programming of the master axis is mandatory. The master-slave association must be defined by the program (refer to the UDA instruction in the Programming Guide).

AXES WITH ROLLOVERThe axes with rollover are linear or rotary axes whose position is controlled by the system within a range from zero to the value configured in the "Rollover pitch" field. The sign of the quote programmed for the axis with rollover indicates the rotation direction: positive, rotation is in a clockwise direction negative, rotation is in an anticlockwise direction.

AUXILIARY AXESAuxiliary axes are interpolated axes that are managed directly by the machine logic. This feature permits to control those axes that do not take part in the machining process but support auxiliary functions such as tool change chains, part change gates, etc. 10 Series CNC can control up to 32 simultaneous auxiliary axes coordinated with one another. Auxiliary axes remain independent from machining axes and work in parallel with the machine tool activities. Example:

STEP

POCKET

Step Pocket

= Distance between two pockets = Generic position of a tool in the tool magazine.

SPINDLE AXISThe spindle axis is the axis on which the tool is mounted during the machining cycle. It may correspond to one of the machine axes.

SPINDLE

Spindle axis with gearsGears are speed reduction devices that can be installed between the motor and the spindle. They enhance the motor performance by allowing to reach a high torque at medium and low speeds. 10 Series CNC MC can control spindles with as many as four different gears. Prior to enabling a range it is necessary to configure the corresponding conversion factor between the maximum voltage applied to the servo drive and the spindle velocity in rpm. It is also possible to configure various "servo loop gain" values for each gear used by the spindle with transducer during spindle orientation. The parameters that configure this feature are: "Voltage for max RPM gear n" "Max speed for gear n".


1-19


Spindle axis ramp10 Series CNC permits to configure whether the converter voltage is to vary uniformly (i.e. follow a variation ramp) or make a step when the programmed rotation speed varies. In spindle drives this control is carried out by an input compensation net. By using the potentialities of the control unit and disactivating the compensation network it is possible to optimize spindle functionality, mainly for threading cycles and orienting. Examples: Spindle axis without ramp.

Vlt o+7.5

-7.5Spindle axis with ramp.

Vlt o+7.5

-7.5

rt

To establish a ramp it is necessary to configure the "reversal time", i.e. the time employed by the spindle for switching from the maximum clockwise rotation speed to the maximum counter clockwise rotation speed with the gear that allows the lowest voltage/speed ratio. Such gear must also be configured. If the ramp is not configured, these parameters must nevertheless be specified because they are used during tapping and boring canned cycles.

1-20



Spindle with trasducerThe position transducer has two basic applications: 1. execution of threading and tapping cycles 2. spindle orientation to a defined position.

Spindle orientationWith 10 Series CNC spindle orientation is made possible by the $SORIENT machine logic function. To compensate the offset between the transducer electrical zero and the spindle physical zero it is possible to define an "Offset for spindle orientation" in the AMP. The orientation cycle is carried out in interpolated mode and requires definition of the following additional parameters to define the execution type. NOTE: The orientation cycle may include the search for the marker and the ensuing reset. This is always so when a channel is opened (SOPEN) or after a SRESET request, provided that the value is greater than 1879048192 transducer pulses. The marker is performed in a speed loop. Speed for Spindle Orientation This parameter defines the threshold of speed below that the control enables spindle positioning. If the orientation request is made when the spindle rotates at a higher speed, the system will take the spindle to a lower speed before enabling the positioning cycle. Acceleration for Orientation This parameter specifies the spindle acceleration during orientation. Since the gears and the loads affect the spindle response, it is advisable to assign to this parameter a value smaller than the result of the following calculation:

Vm 1 * 60 TR*0.5 where: VM TR Is the "Voltage for max RPM" defined for the gear used for setting the "Spindle reversal time". Is the "Spindle reversal time".

NOTE : Speed stop threshold , in position wait and in position window. The orientation phase in which the search for the marker takes place can be performed in two different modes depending on whether these three parameters are set on zero or on.


1-21


If any of them is zero, once the marker has been found the shift from the speed loop to the position loop takes place at once. Otherwise it is possible to have a stop phase between the speed loop (when the marker has been found) and the position loop (when the spindle begins to be positioned according to the orientation angle). This can prevent axle jolts. To this end, the three parameters in question have to be configured correctly: SPEED STOP THRESHOLD (minimum speed threshold below which the spindle is assumed to be stationary during the stop phase after the finding of the marker), IN POSITION WAIT (maximum wait time before the threshold is reached) and IN POSITION WINDOW (time base for the determination of actual spindle speed). If the timeout expires, it is assumed that the spindle has stopped and the spatial positioning stage has started (no emergency is triggered).

Spindle propertiesThe use of a spindle axis can be reserved for a single process, or shared by several processes, or not associated with any process. These three conditions are referred to as EXCLUSIVE, SHARED and RELEASED, respectively. Shared status makes it possible to perform machining cycles in various processes using the spindle axis in common; tapping (G84) and boring (G86), instead, are fixed cycles requiring exclusive use. By analogy, each process is associated with a specific axis status and hence cannot use the spindle in management mode, it can use it either in shared mode or in exclusive mode. At power-up, the spindle starts in a predetermined status, depending on how it has been configured in AMP. If the axis has been configured for a single process, then it will start out in EXCLUSIVE mode, or, if it has been configured for several processes, it will be SHARED. In order to obtain the latter mode, configure the axis completely in a process (field Spindle = Yes): in the other cases, the axis is declared as shared (field Spindle = Shared) with the same id.

Starting from the initial condition, for each process the status of the axis can be changed by means of the GTS triliteral (Get Spindle). Admissible spindle status transitions include: EXCLUSIVE RELEASED: EXCLUSIVE SHARED: SHARED EXCLUSIVE: the owner process using an axis in exclusive mode releases the axis the owner process using an axis in exclusive mode wants to share it a process becomes the sole owner of an axis and acquires it in exclusive mode; this transition cannot be made on an axis shared by several processes the last co-owner process releases the axis a process acquires an axis for exclusive use a process acquires an axis in shared mode

SHARED RELEASED: RELEASED EXCLUSIVE: RELEASED SHARED:

1-22



When a process acquires a new spindle, the current spindle is automatically released. If a process uses the machining cycles associated with a spindle it must always program the S function, in relation to processing needs; in other words, spindle sharing (whether through AMP or GTS) does not result in the automatic setting of actual axis status. For example, let us assume that S1000 is programmed in process 1 and the spindle is acquired by process 2, in the latter the S function continues to be set on the last value programmed for that process, and the spindle keeps revving at 1000 RPM. The management of spindle sharing by several processes is by the machine logic, which will accept or deny axis programming in a process depending on whether or not the axis is already being controlled by another. In this connection, the GTS command opens the logic filter through which the operation requested can be either confirmed or aborted (for a more detailed explanation see the PLUS and WinPLUS application manual). The filter task is not opened in the following conditions: the axis is in the required mode, the request cannot be met (for instance, if you try to obtain the exclusive use of a spindle which is being shared), or an error has occurred. If it is not enabled by the filter, the entire operation is aborted and a process error message is given out. If no errors occur and the filter enables the operation, the spindle makes the transition to the status programmed in the GTS. Notes on some logic functions. 1) The $PARK_SP function does not work on a spindle in SHARED status. 2) The $GET_SP function forces spindle status to EXCLUSIVE, i.e., reserved for exclusive use by the process specified as input to the function.

Configuring a digital spindleIn addition to the analog spindle, a D.S.I. digital spindle, mated to a Bosch-Rexroth drive, can also be configured. For the configuration in AMP, see the section on the spindle axis in chapter 5; for the application notes, see the PLUS/WinPLUS Application Manual. For the configuration of the drive, see the D.S.I. SPINDLE DRIVER SETUP section in this manual.

HANDWHEELThe handwheel is a position transducer connected to one of the encoder inputs of the axes board. By means of the OS-Wire bus it is possible to connect the handwheel to one of the encoder inputs of a Bridge device or to the AUX FEEDBACK input of an OS3 drive. The handwheel makes it possible to move the selected axis by a quantity proportional to the angular variation of the transducer itself. To ensure maximum accuracy, it must comply with the following requirements: 1. The axis to be moved must be a configured axis. 2. The axis and the handwheel must be configured on the same board. 3. The handwheel encoder input must not be associated to any other configured axis. 4. The axis associated to the handwheel must be in idle status, i.e. it cannot be in motion. 5. If the handwheel is active it is not possible to carry out axis motion and axis enable/disable operations directly on the axis. 6. Scale factor, representing the correspondence between handwheel impulses and distance to be covered by the axis, must be chosen correctly. Scale factor in fact, must have a value sufficient to grant the axis a jumpless movement even when the handwheel is moved very fast. For ex.: if the scale factor is very high therefore, if each minimum movement of the handwheel corresponds to a great axis movement, the axis itself could not be able to execute that movement correctly.

A SERVO ERROR may be generated in this situation. Modification of the configured servo error value might be necessary in order to optimize the hamdweel's function (see "POSITION ERROR WITHOUT VFF" description in chapter 5 of this manual)

ENABLE/DISABLE of handwheel is prompted through logic functions (See PLUS Library Manual)

PART PROGRAM-LOGIC INTERFACEThe dialogue between the part program and the machine logic can be synchronous or asynchronous.

Synchronous modeIn this mode the part program makes a series of requests that must be acknowledged before execution. These functions include: motion start/end M functions spindle S functions tool T functions pseudo axes T and S follow predefined rules, whereas M functions are configurable and can be adapted to more specific requirements (refer to Chapter 4, Section "M Codes").

Asynchronous modeThis mode exploits the possibility to render a series of machine logic variables visible to the part program. In the system configuration (see Chapter 3, Section "Logic Configuration") each variable must be associated to a mnemonics (which will be used by the part program) and to an optional initialization value. These variables do not lose their contents when the system is switched off.

Language expansionLogic global variables make it possible for the part program to acquire information that is not directly accessible. For example, the part program can learn the axis position by using an M function in order to command the PLUS logic to carry out the acquisition, write the result in a shared variable (GW or GD) and eventually authorize the part program to resume execution. M100 @ COORD_W Part program: N001 M3 X123.4 Y321.5 M100 N002 E10=@COORDINATE_W N003 Y(E10/2) The logic can use global variables also as preset values or as non-volatile memory. To render these variables inaccessible to the part program they must not be associated to a mnemonics. (M to request the position of the W axis) variable shared with PLUS


1-25


PSEUDO AXESPseudo axes are written in the program without being associated to actual system axes. They are used for requesting the machine logic to execute specific functions. They have the same functionality of the PRELUDE M function. Among the typical pseudo axes functions are: regulation of the water jet, management of secondary spindles, etc.

VIRTUAL AXESThey are used to define some functionalities in AMP like axes virtualization. The only parameter to be configured is the Axis ID. They don't have neither name nor characteristics.

USER INTERFACE10 Series CNC provides a series of predefined video pages that can be enlarged to occupy the full screen or reduced to quadrants that display information about one topic. The size and contents of the video pages and the sequence in which they are displayed can be configured in the AMP (refer to the "Human Interface" chapter in this manual).

Logic displayWith the $WSCREEN PLUS function it is possible to write alphanumeric and or semigraphic color characters in the display areas reserved for the machine logic. The machine logic can also be used for developing those texts that vary through system operation. The SYNOPTIC EDITOR utility, that is also available in the PLUS environment (see Plus User manual), permits the predefinition for each screen of graphics that will be loaded at system bootstrap.

OEM softkeyThe dialogue between the operator and the machine can be facilitated by creating a tree of softkey menus. The meaning of each softkey is application specific and can be established by the machine logic. The softkeys are the tools that permit to give a command, i.e. enable a given machine logic area. Within each area it is therefore necessary to establish the procedures for command recognition and execution. In some cases, activation of the softkey must be accompanied by a data input. The interactions between the system and the operator can be developed by composing the video screens that will be under machine logic control. Such screens prompt the operator to select a course of action by means of the OEM softkeys and/or to input additional bits of information.

VARIABLE SERVO ERRORThe Variable Servo Error feature consists in a new logic control of the Servo Error during axis moves. Usually the Servo Error is taken as absolute (i.e. it is directly compared with the axis tracking error). This new feature allows to consider the Servo Error as an additional element to be added to the theoretical tracking error, the axis is accumulating during its move based on the programmed parameters (speed, gain, active or inactive VFF and VFF%). During the movement, the algorithm is used to determine the theoretical error of the axis (based on the instantaneous velocity of the axis), to which the configured delta is added. If the movement is of type "without VFF" (e.g., it is a manual movement), the error accumulated during the time delay due to the position loop is also added. Once the threshold value has been obtained, it is compared with the following error. The error accumulated during the feedback delay is calculated on the basis of the rapid acceleration and is equal to: Epsi_delay = rapid acc / (kv * 16.6666)

Here 'rapid acc' and 'kv' are in the measurement units of the AMP. THIS SUM IS ONLY CALCULATED ONCE AT START-UP AND NOT CHANGED THEREAFTER.

In order to enable this feature you have to set the value of the movement Servo Error without VFF so that it is smaller than the theoretical error calculated with maximum speed (the Maximum Feed field in AMP) with VFF at zero. Once enabled, the algorithm becomes active for moves with as well as without VFF and takes the delta value from the pertinent configured Servo Errors. The algorithm becomes active at the start of a move if a comparison shows that the Servo Error value is smaller than the theoretical maximum (which is calculated only once at start-up on the basis of the data configured in AMP). If this condition is not met, the algorithm does not start and the Servo Error is taken as an absolute value in the usual manner. The algorithm does not become active, when a VFF value equal to 100% has been configured on the axis during a VFF move (the theoretical error is then zero, therefore the value of the configured Servo Error is directly applied). For Split axes the feature only works on the master axis. This feature is not activated on spindle type axes and with the Electronic Cam function. Change of parameters by the Servo Monitor may change the Servo Error application algorithm.


1-27


Note on the digital axes. Starting from fixup 1 release 7.3, the activation of the algorithm has been extended to the axes with digital interface. For axes of this kind, consider that: 1. the axis reacts according to the KV and VFF gains set on the drive (SERCOS, MECHATROLINK or OS-Wire). Considering that the theoretical error is determined by the CNC based on the KV and VFF values set in AMP, it would be advisable, to the extent feasible, to set the same values on the drive. 2. The following error determined by the CNC is greater than the real axis error due to the time delay in data transmission. Due to these changing conditions, it is not possible to find a mathematical rule for the determination of the threshold to be set in AMP, as is done for analog axes, and the threshold has to be determined empirically through various movement tests performed with the axis in the conditions requested by the application.

Example 1 : maximum feed acceleration Servo Loop gain Position Error with VFF Position Error without VFF VFF% = = = = = = 4000 mm/min 300 mm/sec 1 5 mm 5 mm 100

The theoretical error for comparison at maximum feed without VFF results as 4 mm. Given that the Position Error without VFF is set to 5, the algorithm is not enabled and Servo Error emergency is triggered, when the error exceeds 5 mm. Example 2 : maximum feed acceleration Servo Loop gain Position Error with VFF Position Error without VFF VFF%

= = = = = =

4000 mm/min 300 mm/sec 1 1.5 mm 2.5 mm 100

As in the previous example the theoretical error is 4 mm. For moves with VFF the Position Error without VFF is set to 1.5, but the algorithm is not enabled, because VFF is equal to 100%. Hence Servo Error emergency is triggered when the error exceeds 1.5 mm.

1-28



For moves without VFF the Position Error without VFF is set to 2.5 (i.e. smaller than 4). Therefore the algorithm is enabled and the error delta is 2.5 plus the delay equal to 300 / (16.666) = 3.58. If the current feed is 2000 mm/min, Servo Error emergency is triggered when the error exceeds 2 + 3.58 = 5.58 mm.

Example 3 : maximum feed acceleration Servo Loop gain Position Error with VFF Position Error without VFF VFF%

= = = = = =

4000 mm/min 300 mm/sec 1 1.5 2.5 50

As before the theoretical error for comparison is 4 mm. For moves with VFF the error delta with VFF is 1.5. Assuming a feed of 2000 mm/min is programmed, the theoretical error is 1 mm (as the current feed will be with VFF at 50%). Therefore the Servo Error emergency triggers when the error exceeds 1 + 1.5 + 300 / (16.666) = 3.58 mm. For moves without VFF the error delta is 2.5. With a feed of 3000 mm/min the Servo Error emergency triggers when the error exceeds 3 + 2.5 +1.08 = 6.58 mm.


1-29


RIGID TAPPING PARAMETER CALCULATIONSIn order to correctly build the rigid tapping cycle (see programming manual) you must look for and save two parameters by using the same configuration as VFF that you use during machining. These are the TKG and TAG parameters which represent the compensation coefficients for the command application delay from the servo system for controlling axes and spindle. In particular the TKG parameter is used for recovering errors in the constant speed feed phases while the TAG parameter is used for recovering errors in the axes acceleration and deceleration phases used in tapping (typically the Z axis) Calculation procedure: Before checking that the parameters are correct in the machine AMP, you must configure a fictitious coordinated axis, without convertors or transducers and residing in the process to which the Z axis and the spindle used for the tapping belong. This axis will obviously have an identifier (IDx). You should make this change on a copy of the machine AMP so that you dont have to change again once you have found the parameter values. After switching on the control you have to enter in Manual Data Input the command TMA=IDx where IDx is the identifier of the fictitious axis previously configured. This command is necessary in order to be able to correlate the configured axis with the characterisation of rigid tapping. At this point the Servo Monitor has to be programmed for monitoring the speed of the axis used in tapping (typically Z) and the speed of the fictitious axis. In this case the phase difference between the physical position of the spindle and the position programmed for the Z axis in millimetres is shown on the fictitious axis. By executing tapping cycles without a work piece and each time modifying the TKG and TAG parameters you can achieve to eliminate or almost eliminate the phase difference shown. Practically it is best to work only with the TKG parameter and to eliminate the constant speed error neglecting the error trend in the acceleration phase. Once you have found the correct value for the TKG parameter you then go over and try to find the optimal value for the TAG parameter.

1-30



The next figure shows an example on how this is displayed on the Servo Monitor

V axis Z

AV axis IDX

Once you have found the values for the TAG and TKG parameters, these are valid for all types of tapping, also with spindle steps and speed different from those used for the tests. The values found have to be inserted into a routine or a macro which assigns parameters and has to necessarily be called by all programs which carry out tapping operations.

Operativity notesWhen the user has selected the desired data entry with the proper softkeys, he can start defining the associated parameters with the alphanumeric keyboard. The cursor is automatically positioned on the value field of each parameter. The operator can accept the displayed value or he can insert a new one. If necessary, the operator can move the cursor by using the arrow keys. The correct range of values for each parameter is shown in the Help window that the operator can display by pressing the HELP softkey. In some cases the permissible range is displayed as a list (for example, user variable names, coordinate axis names, etc.). For each entered value, AMP performs range and congruency checks. In case of mistakes, the relevant error message is displayed (see Appendix A) and the cursor remains on the wrong parameter. Some data entries can be listed on more than one screen page. The user can display the various pages by using [Pg Dn] and [Pg Up] keys.

ENTER/EXIT THE CHARACTERIZATION10 Series CNC manages up to 4 "on line" configurations. When the SELECT softkey is used to modify the selected configuration (0, 1, 2 or 3), this is copied in a work directory. All the changes will be made in the work directory. Following configuration (press EXIT), there are 3 alternatives: 1. Perform the secondary calculations transforming the information entered (source files) into a configuration that may be used by the bootstrap (binary files). 2. Save the data entered without performing the secondary calculations (this may also be useful in cases where errors that cannot be eliminated at the time are signalled during the secondary calculations but you want to save the changes made in any case). In this case, any binary files generated previously are lost and care must be taken because, if the AMP directory was the active one, on rebooting the system will not find the binary configuration files and the control will have to be started in emergency mode to generate and activate an AMP configuration. 3. Do not save the new configuration. In this case any changes made are lost. If there were binary files for the previous configuration, these will be maintained as the source files from which they were generated have not been changed. You are advised to use this exit mode when entering the configuration for consultation to avoid losing the binary files. Remember the meaning of the terms Source and Binary for the AMP utility: SOURCE FILES BINARY FILES contain the information entered with the data entry. files generated by the secondary calculations and actually used by 10 Series CNC to configure the machine on starting (BOOTSTRAP).
