Overview of the System

1 Overview of the System

The UFI11A INTERBUS fieldbus interface serves as a gateway for connecting one or
more MOVIDRIVE, MOVIDRIVEcompact or MOVITRAC 07 inverters to INTERBUS. Se­veral inverters can be connected to the INTERBUS UFI11A interface via the SBus. The
INTERBUS UFI11A interface provides the translation between the INTERBUS and the
SBus.

The UFI11A settings can be copied with the UBP11A parameter module from UFI11A
to UFI11A. For safety reasons, all inverters connected to the UFI11A must be turned off
when writing data.

3.1 Installation notes

Mounting

Pin assignment

The unit can be mounted using the integrated DIN rail mounting option or directly onto
a switch cabinet wall using the four holes integrated into the back wall of the housing. In
the latter case, the two retaining screws for the DIN rail mounting must be removed.
Basically, there are no restrictions regarding positioning in relation to the inverters to be
connected (e.g. MOVITRAC
length and the fact that the UFI11A must be the first or last node on the system bus
(SBus).

The UFI11A must have additional HF-compliant grounding if the DIN rail mounting opti­on is used in conjunction with SBus cables more than 1 m in length.

The UFI11A fieldbus interface is equipped with a 9-pin sub D male connector for the in­coming bus signal and a 9-pin sub D female connector for the outgoing bus signal ac­cording to EN 50170.

As a rule, the fieldbus interface is connected to the INTERBUS system using a twisted,
shielded cable. The shield of the INTERBUS cable must be connected on both ends, for
example on the plug housing. Note the maximum supported transmission rate when you
are selecting the bus connector.

The cable is connected to the INTERBUS plug using pins 6 and 1 (/DO and DO) and
pins 7 and 2 (/DI and DI). Communication takes place via these contacts. The RS-485
signals /DO and DO as well as /DI and DI must have the same contacts on all INTER­BUS stations. Otherwise, communication via the bus will not function.

• Switch on the system bus terminating resistor (S1 2 = ON) of the node end of the sys­tem bus. Switch off the terminating resistor on the other units (S12 = OFF). The
UFI11A fieldbus interface must always be the first or last node on the system bus. It
has an integrated terminating resistor.

• There must not be any potential difference between the units connected to the SBus.
Take suitable measures such as connecting each unit’s ground lug to a central
grounding point in the cabinet to avoid potential differences.

• Point-to-point cabling is not permitted.

24 V connection

Shielding and
routing of the bus
cables

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

The voltage range for the 24 VDC voltage supply is 18 – 30 V. The current consumption
of the UFI11A fieldbus interface is 300 mA.

The INTERBUS interface supports RS-485 transmission technology and requires the
cable type specified as the physical medium for INTERBUS. This cable must be a shiel­ded, twisted-pair cable with 3 x 2 cores.

Having the bus cable correctly shielded eliminates parasitic interference which can oc­cur in an industrial environment. The following measures ensure the best possible shiel­ding:

• Finter-tighten the retaining screws of plugs, modules and equipotential bonding con­ductors.

• Use only connectors with a metal housing or a metallized housing.

• Maximize the contact area between the shield and the connector housing.

• Shield the bus cable on both ends.

• Do not route the signal and bus cables in parallel with the power cables (motor
leads); use separate cable ducts if possible.

• Only use grounded-metal cable trays in industrial environments.

• Join the signal cables and the associated equipotential bonding together at closely
spaced intervals by the shortest route.

• Avoid using plug connectors to extend bus cables.

• Route the bus cables closely adjacent to available grounding surfaces.

In the event of fluctuations in the ground potential, a compensating current may flow
along the shield which is connected at both ends and to the ground potential (PE). In this
case, make adequate provision for equipotential bonding in accordance with the rele­vant VDE regulations.

Installation and Operation with Autosetup

3.2 Setting the inverter parameters

The settings can be entered using the inverter control panel. Refer to the inverter ope­rating instructions for more information.

• Switch on the voltage supply for the UFI11A and all connected inverters.

• Set an individual SBus address (P813) on the inverters. Recommendation: Assign
the addresses starting from address 1 and working in ascending order according to
the arrangement of inverters in the switch cabinet. Do not assign address 0 since this
is used by the UFI11A.

• Check the SBus baud rate (P816, factory setting = 500 kbaud).

• Set the Setpoint source (P100) to SBus (value 10).

• Set the Control signal source (P101) to SBus (value 3).

• Set the terminal assignment of the binary inputs. The value 0 is recommended for
P60- in MOVITRAC

–DI01 CW/STOP (applied to 24 V, enable CW direction of rotation)
–DI02 CCW/STOP (applied to 24 V, enable CCW direction of rotation)
–DI03 FIX SETPT SW.OV(not connected)
–DI04 n11/n21 (not connected)
–DI05 n12/n22 (not connected)
–Program the unused terminals to "NO FUNCTION" if you are using a MOVIDRIVE

or MOVIDRIVE compact.

• Important: If you need to set P815 SBus timeout delay for MOVITRAC
only possible using a PC. The default value is 0, which means timeout monitoring is
switched off. Set P815 to the value 1 s.

3.3 Autosetup

Switch on the Autosetup function using the DIP switch on the UFI11A. The function is
active for as long as the SYS-FLT LED is flashing briefly with a long interval between
flashes. The LED stays off after the scanning process if at least one inverter has been
detected.
ted by switching the DIP switch off and on again. The SYS-FLT LED remains on follo­wing Autosetup if no inverter is detected. In this case, check the cabling of the SBus, the
terminating resistors of the SBus, the voltage supply to the inverters and the SBus
address settings (P813).

The Autosetup DIP switch must stay switched on.

3.4 Configuration of the fieldbus master

You will find detailed information in the section "INTERBUS interface."

• Set the required process data length via DIP switches 1 ... 5. You will need three pro­cess data words for each drive inverter connected to the UFI11A. That means you
will have to set 9 words in case you are operating three MOVITRAC

on again.

• Start the "CMD Tool" project planning software for your INTERBUS interface.

• Enter the bus setup via "Configuration frame / Read in" or "Read in configuration
frame."

• Assign program addresses of the control program to the INTERBUS process data of
the inverters. This assignment takes place via the context menu "Process data" or
"Process data manager."

• Enhance the control program by the data exchange with the UFI11A.

3.5 Starting the inverters

You can operate up to eight inverters on the INTERBUS via one UFI11A. The INTER­BUS master and the UFI11A will exchange setpoints and actual values of all inverters
connected to the UFI11A in contiguous data packages. It is important for you to know
where a particular inverter is located in the data package (process image). The relation­ship is shown in the following illustration:
