5.2.2 Bus termination

The PROFIBUS must be terminated by means of a bus terminating resistor at the first and

last physical station.

In the case of the communication unit, the bus terminating resistor can only be installed

externally at the M12 connector. This has the advantage that an installed resistor is visible

when the device is closed.

 Note!

• The PROFIBUS connections (input and output) must be installed in an

enclosed manner. Please use either a connection cable, an enclosed bus

terminator connector (M12 male, 4-pin, B-coded) or a cap.

• Connection cables or bus terminator connectors are offered by several cable

manufacturers (e.g. Lapp or Turck).

• If you want to disconnect individual bus stations, ensure that the bus

terminators at the cable ends remain active. Otherwise, the bus may become

unstable.

• Please observe that the bus termination is not active any longer if ...

– the bus terminator connector has been disconnected;

– the mains supply of the drive unit and the external 24V supply of the

communication unit have been switched off at the same time.
