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.
