3.1 Installation notes

Installation

Pin assignment

The unit can be installed directly onto the wall of a control cabinet by using the pre­installed DIN rail mounting or the four drilled holes on the back of the housing. Basically,
there are no restrictions regarding the spatial arrangement of the units to be connected
(e.g. MOVITRAC

®

07). The maximum line length and the fact that the gateway must be
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
9-pin sub D connector in accordance with EN 50170. The T-bus connection must be
implemented with an appropriately designed plug.

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
3 (B/B

). 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)

Installation and Operation without PC

Installation notes

• Connect the system bus terminating resistor (S12 = ON) at the end of the system bus

connection. Disconnect the terminating resistor at the other devices (S12 = OFF).
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.

Bus termination

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.

3.2 Setting 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.

• 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 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)
– If you use a MOVIDRIVE

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

The Autosetup DIP switch must then remain

• 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.

3.5 Starting the inverters

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

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
word 1. The speed setpoint can be specified with the following word. It is scaled with

0.2 1/min per digit.

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.
