The UFP11A PROFIBUS DP-V1 fieldbus interface is used for connecting inverters with
the PROFIBUS DP-V1. Several inverters can be connected to the UFP11A PROFIBUS
DP-V1 interface via the SBus. The UFP11A PROFIBUS interface establishes the
connection between PROFIBUS DP-VI and SBus.

there are no restrictions regarding the spatial arrangement of the units to be connected
(e.g. MOVITRAC

installed at the end or the beginning of the system bus (SBus) must be taken into
consideration. For this reason, we recommend you take the spatial aspects into
account.
The UFP must have additional HF-compliant grounding if the DIN rail mounting option
is used with SBus cables of more than 1 m in length.
The UFP11A fieldbus interface is connected to the PROFIBUS network by means of a

The fieldbus interface is generally connected to the PROFIBUS system using a shielded
twisted-pair cable. The shielding of the PROFIBUS cable must be attached to both
sides, for example on the connector housing. Observe the maximum supported
transmission rate when selecting the bus connector.
The twisted-pair cable is connected to the PROFIBUS connector via pin 8 (A/A

). Communication takes place via these two contacts. The RS-485 signals A/A
) and pin
and B/B must be contacted in the same way for all PROFIBUS stations. Otherwise, no
communication is possible via the bus medium.
The PROFIBUS interface sends a TTL control signal for a repeater or fiber optic adapter
(reference = pin 9) via pin 4 (CNTR-P).

Please note:
•Use a 2-core twisted and shielded copper cable (data transmission cable with
braided copper shield). Connect the shield with a wide-area contact at the electronics
terminal of MOVITRAC
The cable must meet the following specifications (CAN bus or DeviceNet cables are
suitable, for example):
– Core cross section 0.75 mm
– Cable resistance 120 Ω 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)

The UFP11A gateway must always be connected either at the beginning or the end
of the system bus connection and feature a permanently installed terminating
resistor.
•There must not be any difference of potential between the units connected with the
SBus. Take suitable measures to avoid a difference of potential, such as connecting
the unit ground connectors using a separate line.
•Point-to-point wiring is not permitted.
24 V connection
Shielding and
routing of bus
cables
An external 24 V voltage supply must be connected to terminals X1:4 and X1:5.
The PROFIBUS interface supports the RS-485 communications protocol and requires
cable type A specified for PROFIBUS in accordance with EN 50170 as shielded twistedpair cable for the physical connection.
Correct shielding of the bus cable attenuates electrical interference that may occur in
industrial environments. The following measures ensure the best possible shielding:
•Tighten the mounting screws on the connectors, modules and equipotential bonding
conductors 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 power cables (motor leads). They must
be routed in separate cable ducts.
•Use metallic, grounded cable racks in industrial environments.
•Route the signal cable and the corresponding equipotential bonding in close
proximity using the shortest way possible.
•Avoid using plug connectors to extend bus cables.
•Route the bus cables closely along existing grounding surfaces.
In case of fluctuations in the earth potential, a compensating current may flow via the
bilaterally connected shield that is also connected to the protective earth (PE). Make
sure you supply adequate equipotential bonding according to relevant VDE regulations
in such a case.
A bus termination is not provided on the UFP electronics. If the UFP module is used as
the first or last device of the PROFIBUS line, the bus termination has to be external. We
recommend PROFIBUS connectors with integrated bus termination that open the
continuing bus in case the bus termination is connected.
3.2Setting the inverter parameters
The settings can be entered via the inverter keypad. Refer to the operating instructions
of the inverter for details.
•Connect the voltage supply for the UFx and all connected inverters.
•Set an individual SBus address (P813) at the inverters. Recommendation: Address
setting beginning with address 1 in ascending order based on the arrangement of
inverters in the control cabinet. Address 0 should not be assigned because it is used
by the UFx.
•Set the setpoint source (P100) to SBus (value 10).
•Set the control source (P101) to SBus (value 3).
•Set the terminal assignment of the binary inputs. For MOVITRAC
recommended for P60-. This corresponds to the following assignment:
– DI01 CW/Stop(wired to 24 V, both directions of rotation enabled)
– DI02 CCW/Stop(no function)
– DI03 F.Setp. toggle(not wired)
– DI04 n11/n21(not wired)
– DI05 n12/n22(not wired)

again. First, the UFx searches the lower-level SBUS for drive inverters. This process is
indicated by the SYS-FAULT LED flashing briefly. For this purpose, different SBus
addresses must be set for the drive inverters (P813). We recommend assigning the
addresses beginning with address 1 in ascending order based on the arrangement of
inverters in the control cabinet. The process image on the fieldbus side is expanded by
three words for each detected drive inverter. If no inverter is detected, the SYS-FAULT
LED remains lit. A total of up to eight drive inverters is taken into account. The figure
shows the process image for three drive inverters with three words each of process
output data and process input data. After the search is complete, the UFx cyclically
exchanges three process data words with each connected drive inverter. The process
output data are fetched from the fieldbus, divided into blocks of three and transmitted.
The drive inverters read the process input data, put them together and send them to the
fieldbus master.
Important: If you change the process data assignment of the drive inverters connected
to the UFP, you have to activate Autosetup again because the UFP saves these values
only once during Autosetup. At the same time, the process data assignments of the
connected drive inverters may not be changed dynamically after Autosetup.
The function can be reactivated by turning the DIP switch off and back on
•Set an individual PROFIBUS address using the DIP switches of the UFP for project
planning. The PROFIBUS address is set in binary form. A change of the PROFIBUS
address only becomes effective after switching the UFP off and on again.

•The fieldbus master is configured using the GSD file (see appendix). The UFP is
addressed under the specified PROFIBUS address. The number of process data
words the fieldbus master uses to address the UFP depends on the number of
connected inverters. The process data width for an inverter is three words. If more
than one inverter is present, three words should be planned for each inverter. For
example, you have to configure nine words for three MOVITRAC
®
07 inverters.
•Example for STEP 7:
– Install the GDS file 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, for example "9PD", meaning nine process data words for three
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 (SFC14
and SFC15).
– The BUS-FAULT LED of the UFP should be extinguished after saving the project,
loading it in the DP-V1 master and starting the DP-V1 master. If this is not the
case, check the connections and terminating resistors of the PROFIBUS and the
project planning, especially the PROFIBUS address in STEP 7.
You can operate up to eight inverters on the PROFIBUS using one UFP. The DP master
and the UFP exchange the setpoints and actual values of all inverters connected to the
UFP in coherent data packages. It is important for you to know which inverter is located
at which position of the data package (process image). Figure 5 shows the relationship.
The inverters are enabled by writing the value 0006h to the corresponding control

0.2 1/min per digit.

information
The inverter must be given a specific DP configuration by the DP master to define type
and number of input and output data used for the transmission. You have the opportunity
to control the drives via process data and to read or write all parameters of the fieldbus
interface via parameter channel.

Figure 9: Data exchange with parameter data (Param) and process data (PD)
The fieldbus interface allows for different DP configurations for the data exchange
between DP master and fieldbus interface. The following table provides additional
details on all standard DP configurations of the fieldbus interfaces. The "Process data
configuration" column shows the name of the configuration. These texts also appear as
a selection list in your project planning software for the DP master. The DP
configurations column shows the type of configuration data sent to the fieldbus interface
while the link to PROFIBUS DP is being established. The configurations are determined
by the default process data width for SEW inverters of three process data words. In the
simplest case, the controller transmits three process data words to each inverter
connected to the fieldbus interface. The fieldbus interface then distributes these process
data words to the individual devices. The parameter channel is used for setting the
parameters of the UFP and is not passed on to the connected participants. The fieldbus
interface 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 mode
and allow process data widths of 3PD ... 24PD according to 1 ... 8 inverters connected
to the fieldbus interface.
A maximum of 3PDs can be assigned to any SBus participant!

ONE module for all
drives
The process data are transmitted in one consistent data block for all inverters connected
to the fieldbus interface. Thus, only system functions SFC14 and SFC15 need to be
activated in Step 7.

The configurations under "UFP parameter + ONE module" correspond to those listed

One consistent data block exists for each connected inverter. From the controller side,
this corresponds to the existing setup of several inverters with their own fieldbus
interface. System functions SFC14 and SFC15 need to be executed for each inverter in
Step 7.

"Universal module"
DP configuration
The "Universal Module" configuration (e.g. in STEP7) allows you to set the parameters
of the fieldbus interface deviating from the preset standard values of the GSD file. This
is useful in case you want to operate several inverters with different process data words
at the fieldbus interface.
You must observe the following conditions:
•Module 0 defines the parameter channel of the inverter. Entering 0 will switch off the
parameter channel; entering 243 will switch on the parameter channel with 8 bytes
length.
•The following modules determine the process data width of the fieldbus interface at
the PROFIBUS. The added process data width of all following modules must be
between 1 and 24 words. For safety reasons, the modules must be listed with data
integrity. Make sure that an inverter connected to the fieldbus interface is
represented by such a consistent module entry.
The following figure shows the structure of the configuration data defined in EN 50170
(V2). These configuration data are transmitted to the inverter during the initial start of the
DP master.
Table 1: Format of the Cfg_Data identifier byte according to EN 50170 (V2)
Use only the setting "Integrity over entire length" for data transmission!
Integral data are those data that must always be transmitted consistently between
automation 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 different
program cycles of the automation device and transfer undefined values to the inverter.
For PROFIBUS DP, the data communication always between automation device and
drive engineering is generally carried out with the setting "Data integrity over entire
length."
The fieldbus interface does not support external diagnostics. Error messages of the
individual inverters are indicated by the corresponding status words. Error states of the
fieldbus interface are also displayed on status word 1, for example, timeout of the SBus
connection to a participant.
Upon request, the fieldbus interface provides the standard diagnostics in accordance
with EN 50170 V2.
Diagnostic alarms may also be triggered by the PROFIBUS DP system in the DP master
even if external diagnostic generation is deactivated. As a result, the corresponding
operating blocks (e.g. OB84 for S7-400 or OB82 for S7-300) should always be created
in the controller.
Each DP master and DP slave must have an individual ident number assigned by the
PROFIBUS user group for unique identification of the connected unit. When the
PROFIBUS DP master is started up, it compares the ident numbers of the connected
DP slaves with the ident numbers configured by the user. The user data transfer will only
be activated after the DP master has ensured that the connected station addresses and
device types (ident numbers) correspond to the project planning data. This procedure
achieves a high degree of safety with respect to project planning errors.
The ident number for the UFP11A fieldbus interface is 6004
The ident number is defined as an unsigned 16-bit number (Unsigned16). The
PROFIBUS user group specified ident number 6004 hex (24580 dec) for the UFP11A
fieldbus interface.
5.4Inverter control
The inverter is controlled via the process data channel which is one, two or three I/O
words in length. These process data words may mapped in the I/O or peripheral area of
the controller in case a programmable controller is used as DP master and can be
addressed as usual.

In principle, data lengths of 3 bytes or more than 4 bytes must be transmitted using
system functions SFC14 and SFC15.
This chapter describes the functions and terms used for operating SEW drive inverters
on PROFIBUS DP-V1. Refer to the PROFIBUS user organization or visit
PROFIBUS website for extensive technical information on PROFIBUS DP-V1.
The PROFIBUS DP-V1 specification introduced new acyclical
the context of the PROFIBUS DP-V1 expansions. These acyclical services are inserted
into special telegrams during ongoing cyclical bus operation and thus ensure
compatibility between PROFIBUS DP (version 0) and PROFIBUS DP-V1 (Version 1).
The acyclical
between master and slave (drive inverter) than it would be possible to transfer in the
cyclical input or output data using the 8-byte parameter channel. The advantage of the
acyclical data exchange via DP-V1 lies in the minimum load on the cyclical bus
operation since DP-V1 telegrams are only added to the bus cycle if required.
The DP-V1 parameter channel provides two options for the user:
•The higher-level controller can access the entire inverter information of the SEW DPV1 slaves. This means not only cyclical process data but also unit settings can be
read, stored in the controller and modified in the slave.
•It is also possible to route the service and startup tool MOVITOOLS across the DPV1 parameter channel instead of using a proprietary RS-485 connection for this
purpose. After installing the MOVITOOLS software, detailed information will be
available in the ...\SEW\MOVITOOLS\Fieldbus folder.
The main features of PROFIBUS DP-V1 are explained below.
read/write
services can be used to exchange larger data quantities
Different master classes are distinguished in a PROFIBUS DP-V1 network. The C1
master mainly performs the cyclical data exchange with the slaves. A typical C1 master
is a control system, such as a PLC, that exchanges cyclical process data with the slave.
If the DPV1 function has been activated via the GSD file, the acyclical connection
between C1 master and slave is established automatically when the cyclical connection
of the PROFIBUS-DP is being established. Only one C1 master can be operated in a
PROFIBUS DP-V1 network.
The C2 master itself does not perform cyclical data exchange with the slaves. Examples
for a typical C2 master are visualization systems or temporary installed programming
devices (Notebook / PC). The C2 master uses exclusively acyclical connections for the
communication with the slaves. The acyclical connections between C2 master and slave
are established by the
completed
with the slaves by means of
in a DP-V1 network. The number of C2 connections, which are established to a slave
simultaneously, are determined by the slave. SEW drive inverters support two parallel
C2 connections.
The user data transported via DP-V1 service are collected in a data set. Each data set
is uniquely represented through its length, a slot number and an index. The DP-V1
communication with the SEW drive inverter uses the structure of data set 47, which is
defined as DP-V1 parameter channel for drives starting with V3.1 in the PROFIdrive
profile drive engineering of the PROFIBUS user organization. Different access
procedures to the parameter data of the drive inverter are provided via this parameter
channel.

DP-V1 services
DP-V1 alarm
handling
The DP-V1 expansions offer new services, which can be used for acyclical data
exchange between master and slave. The following services are provided:
The DP-V1 specification not only defines acyclical services, but also includes expanded
alarm handling. Alarm handling distinguishes between different alarm types. As a result,
the unit-specific diagnostics via the DP-V1 service "DDLM_SlaveDiag" is not possible
anymore in DP-V1 operation. No DP-V1 alarm handling was defined for drive
engineering as the drive inverter generally transmits status informaton via cyclical
process data communication.
The SEW fieldbus interfaces according to PROFIBUS DP-V1 have the same
communication features for the DP-V1 interface. Basically, the drives are controlled via
a C1 master according to the DP-V1 standard with cyclical process data. In the case of
cyclical data exchange, the C1 master (usually a PLC) can additionally use an 8-byte
parameter channel to perform parameter services with the UFP. The UFP cannot
access connected MOVITRAC
write services give the C1 master access to connected participants via the DP-V1 C1
channel.
Two C2 channels can be established in addition to these two parameter channels. The
first C2 master can use the C2 channel, for example, to read parameter data as
visualization. A second C2 master in the form of a notebook configures the drive using
MOVITOOLS.

If the bus cycle time is short, the parameter response is queried earlier than the inverter
has completed the parameter access in the unit. As a result, the response data from the
inverter are not yet ready at this time. In this state, the inverter sends a negative
response on DP-V1 level with Error_Code _1 = 0xB5 (status fault). The DP-V1 master
must then send another request with above Read.req header until the drive inverter
sends a positive response.

MoviLink
parameter orders
The MoviLink parameter channel of the SEW drive inverters is directly mapped in the
structure of data set 47. The Request ID 0x40 (SEW MoviLink service) is used for the
exchange of MoviLink parameter setting orders. Parameter access with MoviLink
services usually takes place according to the structure described below. The typical
message sequence for data set 47 is used for this purpose.
Request ID:0x40 SEW MoviLink Service
The actual service is defined by the data set element

on the MoviLink
parameter channel. The high nibble of this element corresponds to the service nibble in
the management byte of the DPV0 parameter channel.
The following tables show an example of the structure of the Write.request and Read.res
user data for reading an individual parameter via the MoviLink parameter channel.

The PROFIdrive parameter channel of SEW drive inverters is directly mapped in the
structure of data set 47. Parameter access with PROFIdrive services usually takes place
according to the structure described below. The typical message sequence for data
set 47 is used for this purpose. PROFIdrive only defines the two request IDs
That is why data access is limited compared to the MoviLink services.
The request ID = 0x02 = Change Parameter (PROFIdrive) results in a remanent write
access to the selected parameter. Consequently, the internal flash/EEPROM of the
inverter is written with each write access. Use the MoviLink service "Write Parameter
volatile" if parameters must be written cyclically at short intervals. With this service, you
alter the parameter values only in the RAM of the inverter.
The following tables show an example of the structure of the Write.request and Read.res
user data for reading an individual parameter via the MoviLink parameter channel.

A special GSD file is required for the project planning of a DP-V1 C1 master. This file
activates the DP-V1 functions of the UFP. For this purpose, the GSD file and the
firmware of the UFP must correspond in terms of functions. After introduction of the DPV1 functions, SEW-EURODRIVE supplies two GSD files. Selecting the GSD file: see the
table "Validity of GSD files for UFP."

The GSD files for PROFIBUS DP-V1 are displayed in a special subdirectory in the
project planning software for the DP-V1 master. The figure shows the representation in
the hardware configuration of STEP7.
As a rule, the operating mode DP-V1 can be activated during project planning for a C1
master. All DP slaves, which have the DP-V1 functions enabled in their GSD files and
which support DP-V1, will then be operated in the DP-V1 mode. Standard DP slaves
remain to be operated via PROFIBUS DP, which ensures the combined operation of DPV1 and DP-capable modules. A DP-V1 capable participant, which was configured with
the DP-V1 GSD file, can also be operated in the „DP' mode depending on the master
functionality.

Switching off the fieldbus master or an open circuit of the fieldbus cabling leads to a
fieldbus timeout at the UFx. The connected drive inverters are switched to a safe state
by sending zeros to the process output data which corresponds, for example, to a rapid
stop on control word 1. The fieldbus timeout error resets itself, which means the drive
inverters receive the current process output data from the controller once the fieldbus
communication has been reestablished. This error response can be deactivated via
P831 of the UFx.
If one or several drive inverters at the SBus can no longer be addressed by the UFx, the
UFx displays error code 91 "System error" on status word 1 of the respective drive
inverter. The SYS-FAULT LED lights up and the error is also indicated via diagnostic
interface. It is necessary to set the SBus timeout interval P815 of the MOVITRAC
system error to a value other than 0 for the drive inverter to stop. The error resets itself
at the UFx, which means the current process data are exchanged immediately after
restarting the communication.

7.3Device errors
UFx gateways detect a series of hardware defects and lock out subsequently. The exact
error responses and remedies can be found in the list of errors. A hardware defect
causes error 91 to be displayed on the fieldbus process input data for status words 1 of
all drive inverters. The SYS-FAULT LED at the UFx then flashes at regular intervals. The
exact error code is displayed via MOVITOOLS in the UFx status at the diagnostic
interface.
The UFP PROFIBUS interface has four diagnostic LEDs.
•"RUN" LED (green) for displaying the normal operating status
•"BUS-FAULT" LED (red) for displaying errors at the PROFIBUS DP-V1
•"SYS-FAULT" LED (red) for displaying UFP system errors and operating states.
•"USER" LED (green) for application-specific diagnostics in expert mode.

addressed by the DP master. Check configuration of the DP master. The configured
PROFIBUS address must be identical to the PROFIBUS address set on the DIP

settings for project planning (do not use a universal configuration).

or the connected inverters do not respond. Repeat the configuration of the UFP. If the
UFP was started with Autosetup, switch the Autosetup DIP switch off and on again. If
the LED is still lit after Autosetup, check the cabling and the terminating resistors of
the SBus as well as the voltage supply of the inverter. If the UFP was started using
MOVITOOLS, select the "Update" button in the manager. All inverters should be
displayed in the "Connected Inverters" window. If this is not the case, check the
cabling and the terminating resistors of the SBus as well as the voltage supply of the
inverter. If necessary, repeat the configuration of the UFP with MOVITOOLS.

AUTO SETUP: See Sec. "Installation and Operation with Autosetup"
9.1Setting the station address
The PROFIBUS station address is set using DIP switches. PROFIBUS supports the
address range from 0 through 125.
It is not possible to change the PROFIBUS station address via DIP switches during
operation of the UFP11A. The modified station address will only become effective after
switching the UFP11A on again.
You can control the current PROFIBUS station address with parameter
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,
Assembler and Compiler on all connected inverters via the gateway.
The UFx configurator 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 processed
online.
It is advisable to verify that the hardware Autosetup is switched off (DIP switch 8
in OFF position) before starting the UFx configurator.
Before startup, make sure that neither personnel nor system components are at
risk if a bus error should occur on the PROFIBUS and/or system bus end.
Two modes are available for project planning/startup.
The Autoconfiguration mode sequentially assigns each participant three process output
and input data analogous to the hardware AutoSetup, beginning with the lowest system
bus address.
Autoconfiguration: 3 participants with addresses 10, 11 and 12 => 9 PDs
Figure 14: Autoconfiguration example
The process data assignment can be configured at random in expert mode. The
assignment can take place graphically (drag and drop).
Packaging or bundling the process output data may look as follows: PO1 ... PO3 are
received by all 3 participants (e.g. control word 1, speed setpoint, ramp).
The PROFIBUS master receives 1 PD (e.g. status word 2) from each inverter as process
input data. Six process output and process input data words are saved in the peripheral
area in the master compared to AutoSetup.
A multiple assignment of process input data should be avoided/does not make sense.

The GSD file supports the configuration of a corresponding process data width in the
PROFIBUS master. If a process data width is not listed, select the next higher one (e.g.
FAULT LED of the UFx. If this LED
is on, one or several participants
on the SBus could not be

reported to the controller only via
fieldbus.
