System Overview

1 System Overview

The UFP11A PROFIBUS DP fieldbus interface is used for connecting inverters with the

PROFIBUS DP. Several inverters can be connected to the UFP11A PROFIBUS DPinterface via the SBus. The UFP11A PROFIBUS interface establishes the connectionbetween PROFIBUS DP and SBus.

3.1 Installation notesInstallation The unit can be installed directly onto the wall of a switch cabinet by using the

preassembled DIN rail mounting option or the four drilled holes on the back of thehousing. In the latter case, you will have to remove the two mounting screws of the DINrail mounting option. You can connect any additional units (e.g., MOVITRAC 07) thebest way you seem to see fit taking into consideration the maximum line length and thefact that the gateway must be installed at the end or the beginning of the system bus(SBus). For the same reason, we recommend you take the spatial aspects into account.

The UFP must receive an additional HF-capable ground if the DIN rail mounting optionis used with an SBus line length of more than 1 m.

Connector

assignment

The UFP11A fieldbus interface is connected to the PROFIBUS network by means of a

9-pole sub-D connector in accordance with EN 50170. The T-bus connection must beimplemented with an appropriately designed plug.

The connection of the fieldbus interface to the PROFIBUS system is generallyimplemented with a shielded twisted-pair cable. The shielding of the PROFIBUS cablemust be attached to both sides, for example on the connector housing. Observe themaximum supported transmission rate when selecting the bus connector.

The twisted-pair cable is connected to the PROFIBUS receptacle via pin 8 (A/A) and pin3 (B/B). Communication takes place via these two contacts. The RS-485 signals A/Aand B/B must be contacted in the same way for all PROFIBUS participants. Otherwise,no communication is possible via the bus medium.

The PROFIBUS interface delivers a TTL control signal for a repeater or fiber opticadapter (reference = pin 9) via pin 4 (CNTR-P).

Connection

Please note:

Use a 2-core twisted and shielded copper cable (data transfer cable with shieldconsisting of copper braiding). Connect the shield with a wide-area contact at theelectronics terminal of MOVITRAC 07 or UFP11A and also connect the shield endsto GND. The cable must meet the following specifications (CAN bus or DeviceNetcables are suitable):

Core cross-section 0.75 mm2 (AWG18) Cable resistance 120 at 1 MHz Capacitance per unit length 40 pF/m (12 pF/ft) at 1 kHz

The approved total cable length depends on the specified SBus baud rate:

250 kBaud: 160 m (528 ft) 500 kBaud: 80 m (264 ft) 1000 kBaud: 40 m (132 ft)

PROFIBUS Interface

Connect the system bus terminating resistor (S12 = ON) at the end of the system busconnection. Disconnect the terminating resistor (S12 = OFF) at the other devices.The UFP11A gateway must always be connected either at the beginning or the endof the system bus connection and feature a permanently installed terminating

resistor.

24 V connection An external 24 V voltage supply must be connected to terminals X1:4 and X1:5.

The voltage range for the 24 V voltage supply is 18 30 V. The current consumptionof the UFP11A gateway measures 300 mA.

Shielding androuting of buscables

The PROFIBUS interface supports the RS-485 communications protocol and requirescable type A specified for PROFIBUS in accordance with EN 50170 as shielded twisted-pair cable for the physical connection.

Professional shielding of the bus cables attenuates electrical interference that mayoccur in industrial environments. The following measures will result in the best shieldingproperties:

Fasten the mounting screws on the connectors, modules and equipotential bondingconductors by hand.

Use only connectors with metal housing or plated housing.

Connect the shielding in the connector with the greatest possible surface area.

Attach the shielding of the bus line on both sides.

Do not route signal and bus cables parallel to line cables (motor leads). They mustbe routed in separate cable ducts.

Use metallic, grounded cable racks in commercial environments.

Route the signal cable and the corresponding equipotential bonding in closeproximity using the shortest way possible.

Avoid the extension of bus lines by means of plug connectors.

Route the bus cables closely along existing grounding surfaces.

Bus termination A bus termination is not provided with the UFP electronics. If the UFP module is usedas the first or the last device of the PROFIBUS line, the bus termination has to beexternal. We recommend PROFIBUS connectors with integrated bus termination thatopen the continuing bus in case the bus termination is connected.

No potential displacement may occur between the units connected with the SBus.Avoid a potential displacement using appropriate measures, such as connecting theunit ground with a separate line.

Point-to-point wiring is not permissible.

In case of fluctuations in the earth potential, a compensating current may flow via thebilaterally connected shield that is also connected to the protective earth (PE). Makesure you supply adequate equipotential bonding according to relevant VDE regulationsin such a case.

3.2 Startup of Profibus DP Master

Observe the notes in the README.TXT file on the GSD disk.

Install the "SEW_6004.GSD" GSD file according to the requirements of the project

planning software for the DP master. After successful installation, the "UFP" deviceappears at the slave participants.

Insert the fieldbus interface into the PROFIBUS structure under the name "UFP" andassign the PROFIBUS address.

Select the process data configuration required for your application (see next section).

Enter the I/O or peripheral addresses for the configured data widths.

Save the configuration.

Expand your application program by the data exchange with the fieldbus interface.In case of S7, use the system functions for consistent data exchange for this purpose(SFC14 and SFC15).

The BUS-FLT LED of the fieldbus interface should extinguish after you have savedthe project, loaded it in the DP master and started the DP master. If this is not thecase, please check cabling and terminating resistors of the PROFIBUS and theproject planning, especially the PROFIBUS address.

3.3 Configuration of the Profibus DP interface

Generalinformation

the inverter must be given a specific DP configuration by the DP master to define typeand number of input and output data used for the transmission. It allows for theopportunity to control the drives via process data and to read or write all parameters ofthe fieldbus interface via parameter channel.

The figure shows a schematic view of the data exchange between automation device(DP master), fieldbus interface (DP slave) and an inverter with process data channel andparameter channel.

Process dataconfiguration

The fieldbus interface allows for different DP configurations for the data exchangebetween DP master and fieldbus interface. The following table gives additional detailson all standard DP configurations of the fieldbus interfaces. The Process dataconfigurationcolumn shows the name of the configuration. These texts also appear as

a selection list in the project planning software for the DP master. The DPconfigurations column shows the type of configuration data sent to the fieldbusinterface while the link to PROFIBUS DP is being established. The configurations aredetermined by the default process data width for SEW inverters of 3 process data words.In the simplest case, the controller transmits 3 process data words to each inverterconnected to the fieldbus interface. The fieldbus interface then distributes these processdata words to the individual devices. The parameter channel is used for setting theparameters of the UFP and is not passed on to the lower-level participants. The fieldbusinterface accepts 1 ... 24 process data words with and without parameter channel.

The standard entries of the GSD file are based on the UFP Autosetup operating modeand allow process data widths of 3PD ... 24PD according to 1 ... 8 inverters connectedto the fieldbus interface.

ONE module for alldrives

The configurations under "ONE module for all drives" do not contain any parameterchannels. The transmission of process data is carried out in one consistent data blockfor all inverters connected to the fieldbus interface. Thus, only system functions SFC14and SFC15 need to be executed in Step 7.

UFP parameter +ONE module

The configurations under "UFP parameter + ONE Module" correspond to those listedabove. The parameter module that allows for a parameter setting of the UFP with eight(8) consistently transmitted bytes will be processed first.

One module perdrive

The configurations under "One module per drive" do not contain any parameterchannels. One consistent data block exists for each connected inverter. From thecontroller side, this corresponds to the existing setup of several inverters with their ownfieldbus interface. Thus, system functions SFC14 and SFC15 need to be executed foreach inverter in Step 7.

UFP parameter +One module perdrive

The configurations under "UFP parameter + One module per drive" correspond tothose listed above. The parameter module which allows for a parameter setting of thefieldbus interface using eight (8) consistently transmitted bytes will be processed first.

Any SBus participant can be assigned a maximum of 3 PDs!

"Universal Module"DP configuration

The "Universal Module" (e.g. in STEP7) allows you to set the parameters of the fieldbusinterface deviating from the preset standard values of the GSD file. This is useful in caseyou want to operate several inverters with different process data words at the fieldbusinterface.

You must observe the following conditions:

Module 0 defines the parameter channel of the inverter. Entering 0 will switch off theparameter channel; entering 243 will switch on the parameter channel with 8 byteslength.

The following modules determine the process data width of the fieldbus interface atthe PROFIBUS. The added process data width of all following modules must bebetween 1 and 24 words. For safety reasons, the modules must be listed with dataintegrity. Make sure that an inverter connected to the fieldbus interface isrepresented by such a consistent module entry.

The special identifier format is permitted.

The following figure shows the structure of the configuration data defined in EN50170(V2). These configuration data are transmitted to the inverter during the initial startof the DP master.

PROFIBUS Interface

Data integrity Integral data are those data that must always be transmitted consistently betweenautomation device and inverter and may never be transmitted separately.

Data integrity is especially important for the transmission of positioning values or

complete positioning tasks. Inconsistent transmission may contain data from differentprogram cycles of the automation device and transfer undefined values to the inverter.

For PROFIBUS DP, the data communication between automation device and driveengineering devices is generally carried out with the setting Data integrity over entirelength.

Externaldiagnostics

The fieldbus interface does not support external diagnostics. Error messages of theindividual inverters are indicated by the corresponding status words. Error states of thefieldbus interface are also displayed on status word 1, e.g. timeout of the SBUSconnection to a participant.

Upon request, the fieldbus interface provides the standard diagnostics in accordance

with EN 50170 V2.

Note on Simatic S7Master Systems

Diagnostic alarms may also be triggered by the PROFIBUS DP system in the DP mastereven if the external diagnostic generation is deactivated. As a result, the correspondingoperating blocks (e.g. OB84 for S7-400 or OB82 for S7-300) should always be createdin the controller.

3.4 Ident number

Each DP master and DP slave must feature an individual ident number assigned by thePROFIBUS user group for unique identification of the attached device. When the

PROFIBUS DP master is started up, it compares the ident numbers of the connectedDP slaves with the ident numbers configured by the user. The user data transfer will onlybe activated after the DP master has ensured that the connected station addresses anddevice types (ident numbers) correspond to the project planning data. This procedureachieves a high degree of safety with respect to project planning errors.

The ident number for the UFP11A fieldbus interface is 6004hex.

The ident number is defined as an unsigned 16-bit number (Unsigned16). ThePROFIBUS user group specified ident number 6004 hex (24580 dec) for the UFP11Afieldbus interface.

3PROFIBUS Interface

3.5 Inverter control

The inverter control takes place via the process data channel which is one, two or threeI/O words in length. These process data words may be mapped in the I/O or peripheral

area of the controller in case a programmable controller is used as DP master and canbe addressed as usual.

PA = process output data / PE = process input data

Additional information on programming and project planning can be found in theREADME_GSD6004.PDF file included in the GSD file.

Control examplefor Simatic S7

The inverter control via Simatic S7 takes place in dependence of the selected processdata configuration, either directly via load and transfer commands or via the specialsystem functionsSFC 14 DPRD_DATand SFC15 DPWR_DAT.

In principle, data lengths with 3 bytes or more than 4 bytes must be transmitted viasystem functions SFC14 and SFC15 for S7. Thus, the following table applies:

STEP7programmingexample

The "README_GSD6004.PDF" file contains project planning and program examplesfor Simatic S7.

3.6 Setting parameters via PROFIBUS DP

The drive parameters for PROFIBUS DP are accessed via the MOVILINK parameterchannel which offers additional parameter services next to the traditional READ and

WRITE services.

Structure of theparameterchannel

The access to the UFP11A parameters for PROFIBUS DP is carried out via the"Parameter Process data Object" (PPO). This PPO is transmitted cyclically and containsthe process data channel as well as a parameter channel that can be used to exchangeacyclical parameter values.

3PROFIBUS Interface

The following table shows the structure of the parameter channel. It basically consistsof a management byte, an index word, a reserved byte and four data bytes.

Administration ofthe parameterchannel

The entire parameter adjustment process is coordinated with the administration byte 0.This byte makes available important parameters, such as service identifier, data length,version and status of the executed service. The following table shows that bit 0, 1, 2 and3 contain the service identifier, thereby defining which service is executed. Bit 4 and bit5 specify the data length in byte for the write service which generally should be set to 4bytes for SEW slaves.

Bit 6 serves as handshake between controller and slave. It triggers the execution of thetransferred service in the inverter. Since the parameter channel is transferred in eachcycle along with the process data for PROFIBUS DP, the execution of the service in theinverter must be edge-triggered by handshake bit 6. The value of this bit is toggled eachtime a new service is to be executed. The slave uses the handshake bit to signal

whether the service has been executed or not. The service is executed as soon as thecontroller notices that the received and transmitted handshake bits are identical. Statusbit 7 indicates whether the service was executed properly or if it produced an error.

PROFIBUS Interface

Index addressing "Byte 2: Index High" and "byte 3: Index Low" are used to identify the parameter to beread or written via the fieldbus system. The parameters of an SEW slave are addressedwith a uniform index independent of the connected fieldbus system. Byte 1 should beconsidered reserved and must generally be set to 0x00.

Data area As shown in the following table, the data is contained in byte 4 through byte 7 of theparameter channel. This allows a maximum of 4 byte data to be transmitted for eachservice. The data is generally entered flush right, i.e. byte 7 contains the least significantdata byte (LSB data), byte 4 correspondingly the most significant data byte (MSB data).

Faulty serviceexecution

Faulty service execution is signaled by setting the status bit in the administration byte.If the received handshake bit is identical to the transmitted handshake bit, the slave hasexecuted the service. If the status bit indicates an error, the error code is entered in thedata area of the parameter message. Bytes 4 through 7 provide the return code in astructured format (see Return Codes section).

3.7 Parameter setting of return codes

If parameters are incorrectly adjusted, the slave returns various return codes to theparameter setting master providing detailed information on the cause of the error. In

general, these return codes feature a structured design. The following components arebeing distinguished:

error class

error code

additional code

A detailed description of these return codes can be found in the manual accompanyingthe fieldbus communications profile. They are not listed separately in thisdocumentation. However, the following special cases may occur in connection withPROFIBUS:

Error class The error class component provides a more exact classification of the error type. TheUFP11A fieldbus interface supports the following error classes defined in accordancewith EN 50170(V2):

Except for Error Class 8 = Other Error, the error class is generated by thecommunications software of the fieldbus card in case of a faulty communication. Returncodes provided by the SEW slave fall under the category Error Class 8 = Other Error.The more detailed error breakdown is achieved with the additional code component.

Error code The error code component allows for a more detailed breakdown of the error causewithin the error class and is generated by the communications software of the fieldbus

card in the case of a faulty communication. ForError Class 8 = Other Error, onlyErrorCode = 0(Other error code) is defined. In this case, the detailed breakdown takes placein theAdditional Code.

3.8 Special cases

Special returncodes (specialcases)

Parameter setting errors that are neither recognized automatically by the applicationlayer of the fieldbus system nor by the system software of the inverter are treated asspecial cases. This includes the following possible errors, depending on the fieldbusoption card used:

Installation and Operation with Autosetup

4 Installation and Operation with Autosetup

4.1 AutosetupThe Autosetup function allows the startup of the UFx without a PC. It is activated bymeans of the Autosetup DIP switch. Activating the Autosetup DIP switch causes a singleexecution of the function. The function can be executed again by switching it off and onagain. First, the UFx searches the lower-level SBUS for drive inverters and indicates thisthrough brief flashing of the SYS-FLT LED. For this purpose, different SBUS addressesmust be set at the drive inverters (P813). It is recommended assigning the addressesbeginning with address 1 in ascending order based on the arrangement of the invertersin the control cabinet. For each located drive inverter, the process image on the fieldbusside is expanded by 3 words. If no drive inverter was located, the SYS-FLT LED remainslit. A maximum number of 8 drive inverters is taken into consideration. The figure showsthe process image for 3 drive inverters with 3 words each of process output data and

process input data. At the conclusion of the search, the UFx cyclically exchanges 3process data words with each connected drive inverter. The process output data isfetched by the fieldbus, divided into blocks of 3 and transmitted. The process input datais read by the drive inverters, grouped and transmitted to the fieldbus master.

Autosetup must be executed only once. The detected configuration is saved in non-volatile memory. See the section on "Installation and Operation without PC."

Caution: Please execute autosetup again if you change the process data assignment ofthe drive inverters connected to the UFP since the UFP uniquely stores these valuesduring autosetup. At the same time, the process data allocations of the connected driveinverters may not be changed dynamically after autosetup, for example by means of anIPOS program.

4.2 Installation and cabling

For installation notes, see the "PROFIBUS Interface" section.

4.3 Setting the inverter parameters

The settings can be performed via the inverter keypad; please observe the operatinginstructions of the inverter.

Connect the voltage supply for the UFx and all connected inverters.

Set an individual SBus address (P813) at the inverters. Recommendation: Addresssetting beginning with address 1 in ascending order based on the arrangement of theinverters in the control cabinet. Address 0 should not be assigned since it is used bythe UFx.

Verify the SBus baud rate (P816, factory setting = 500 kBaud).

Set the setpoint source (P100) to SBus (value 10).

Set the control source (P101) to SBus (value 3).

Set the terminal assignments of the binary inputs. For MOVITRAC 07, the value 0is recommended for P60-. This corresponds to the following assignment:

DI01 CW/Stop (wired to 24 V, CW direction of rotation enabled) DI02 CCW/Stop (wired to 24 V, CCW direction of rotation enabled) DI03 F.Setp. toggle(not wired) DI04 n11/n21 (not wired) DI05 n12/n22 (not wired) If you use a MOVIDRIVE unit as inverter, you must program the terminals that

are not used to "No function."

Caution: For MOVITRAC 07, P815 SBus timeout interval can only be adjusted viaPC, if necessary; the default value is 0, i.e. timeout monitoring is deactivated. SetP815 to the value 1 s.

4.4 Autosetup

Activate the Autosetup function via the DIP switch of the UFx. The function is active aslong as the SYS-FLT LED flashes briefly followed by a long pause. At least one detectedinverter causes the LED to extinguish. Autosetup can be reactivated by turning the DIP

switch off and on again. If no inverter is detected, the SYS-FLT LED remains lit afterautosetup. In this case, check the cabling of the SBus, the terminating resistors of theSBus, the voltage supply of the inverter and the set SBus addresses (P813).


25/44


4Installation and Operation with Autosetup

4.5 Project planning of the fieldbus master

Set an individual PROFIBUS address via the DIP switches of the UFP for projectplanning. The PROFIBUS address is set in binary form. A change of the PROFIBUS

address becomes effective only after switching the UFP off and on again.

The fieldbus master is configured using the sew_6004.gsd file. The UFP isaddressed under the specified PROFIBUS address. The number of process datawords the fieldbus master uses to address the UFP is dependent on the number ofconnected inverters. The process data width for an inverter is three (3) words. If morethan one inverter is present, three (3) words should be planned for each inverter. Forexample, you must configure nine (9) words for three (3) MOVITRAC C07.

Example for STEP7:

Install the GSD file sew_6004.gsd in the STEP 7 software. In HW Config of the hardware catalog, insert the UFP at the PROFIBUS. Select the setting suitable for your application from the presented process data

configurations, e.g. "9 PD" meaning nine (9) process data words for three (3)inverters.

Save the configuration. Expand your application program by the data exchange with the UFP. For this

purpose, use the system functions of S7 for consistent data exchange (SFC14and SFC15).

The BUS-FLT LED of the UFP should be extinguished after saving the project,loading it in the DP master and starting the DP master. If this is not the case,please check cabling and terminating resistors of the PROFIBUS and the project

planning, especially the PROFIBUS address in STEP 7.

Installation and Operation with PC

Save the project data and press the "Download" button. If the download should notwork, you have probably set the DIP switch to AUTOSETUP. The autosetup functionmust be deactivated for the PC project planning.

The data exchanged between fieldbus master and UFP can be viewed via theprocess data monitor.

Enabling on the terminal side is required to control the inverters via fieldbus. Youhave already wired the terminals. Please select the first inverter with address 1 in theConnected devices window and start Shell to check the terminal assignment. ForMOVITRAC 07, the terminal assignment should be set as follows:

Repeat the previous step for all inverters displayed in the Connected deviceswindow.

5.4 Project planning of the fieldbus master

Set an individual PROFIBUS address via the DIP switches of the UFP for the projectplanning. The PROFIBUS address is set in binary form. A change of the PROFIBUSaddress becomes effective only after switching the UFP off and on again.

The fieldbus master is configured using the sew_6004.gsd file. The UFP isaddressed under the specified PROFIBUS address. The number of process datawords the fieldbus master uses to address the UFP depends on the number ofconnected inverters and the specified process data width. A recommended valuewas presented in the PC project planning of the module. The GSD file offers processdata configurations in steps of three. If your configuration cannot be divided by 3,simply use the next higher one.

Example for STEP 7:

Error responses

6 Error responses

6.1 Fieldbus TimeoutSwitching off the fieldbus master or an open circuit of the fieldbus cabling leads to afieldbus timeout at the UFx. The connected drive inverters are switched to a safe stateby sending zeros to the process output data. This corresponds to a rapid stop on controlword 1. The fieldbus timeout error resets itself, i.e. the drive inverters will once againreceive the current process output data from the controller once the fieldbuscommunication has been reestablished. This error response can be deactivated viaP831 of the UFx.

6.2 SBUS Timeout

If one or several drive inverters at the SBUS can no longer be addressed by the UFx,the UFx displays the error code 91 System error on status word 1 of the respectivedrive inverter. The SYS-FLT LED lights up and the error is also indicated via diagnosticsinterface. It is necessary to set the SBUS timeout interval P815 at the inverter to a valueother than 0 for the drive inverter to stop. The error resets itself at the UFx, i.e. thecurrent process data are exchanged immediately after restarting the communication.

6.3 Device error

The UFx gateways detect a series of hardware defects and lock out subsequently. Theexact fault responses and remedies can be found in the list of errors. A hardware defect

causes the display of error 91 on the fieldbus process input data for status words 1 of alldrive inverters. The SYS-FLT LED at the UFx flashes at regular intervals. The exacterror code is displayed via MOVITOOLS in the UFx status at the diagnostics interface.

Operating the Interface

9 Operating the Interface

How do I go

"online?"

After an "Update," the MOVITOOLS manager displays all participants recognized on the

system bus, i.e. inverters and gateway. You can access the status bar, Shell, Assemblerand Compiler on all connected inverters via the gateway.

MT-Gateway supports the project planning and startup of a UFP fieldbus node.

A bus configuration can either be configured offline or read from the UFP and processedonline.

Project planning/startup

Two modes are available for project planning/startup.

The Autoconfiguration mode sequentially assigns each participant three (3) processoutput and input data analogous to the hardware AutoSetup, beginning with the lowestsystem bus address.

Example Autoconfiguration: Three (3) participants with addresses 10, 11 and 12 => 9PDs

The process data assignment can be configured at random in expert mode. Theassignment can take place graphically (drag and drop).

It is advisable to verify that the hardware AutoSetup is switched off (DIP switch 8in position OFF) before beginning an MT-Gateway session.

Make sure that neither personnel nor system components are at risk if a bus errorshould occur on the PROFIBUS and/or system bus end.

Packaging or bundling the process output data may look as follows: PO1..PO3 allreceive three (3) participants (e.g. control word 1, speed setpoint, ramp).

The Profibus master receives 1PD (e.g. status word 2) from each inverter as processinput data. Six (6) process ouput and input data words are saved in the peripheral areain the master compared to AutoSetup.

A multiple assignment of process input data should be avoided/does not make sense.
