5.2.1 Network topology

The following examples show two simple RS485 networks.

Every segment of the network must be terminated at both ends. The bus terminators of
the PROFIBUS are marked with a "Z" in the below examples.

With a RS485 network of only one segment, the PROFIBUS master (M) with the integrated
bus terminating resistor starts the bus. The bus must be terminated by means of a bus
terminating resistor at the last PROFIBUS station (S).

Electrical installation

If no repeater is to be used at the end of the segment, the bus must be terminated by
means of a bus terminating resistor at the last station (S). The bus termination is supplied
by this station.

An external supply of the communication unit provides for a supply of the bus termination
independent of the supply of the controller.

 Note!

The bus terminator must always be supplied. Otherwise, the bus can get
unstable.

 Tip!

Repeaters do not have a station address. When calculating the maximum number
of stations, they reduce the number of stations by 1 on each side of the segment.

Repeaters can be used to build up line and tree topologies. The maximum total bus
system expansion depends on ...

• the baud rate used;

• the number of repeaters used.

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.

Bus cable length

The bus cable length depends on the baud rate used:

Baud rate Length

187.5 kbps 1000 m

500 kbps 400 m

1500 kbps 200 m

3000 ... 12000 kbps 100 m

 Note!

The baud rate depending of the data volume, cycle time and number of stations
should only be selected as high as required for the application.

 Tip!

For high baud rates, we recommend taking the use of optical fibres into
consideration.

Advantages of optical fibres:

• External electromagnetic interferences have no effect on the transmission
path.

• Bus lengths of several kilometres are also possible with higher baud rates.
The bus length is ...

– independent of the baud rate;
– dependent on the optical fibre used.

Commissioning
Before initial switch-on

6 Commissioning

During commissioning, plant-specific data such as motor parameters, operating
parameters, responses, and parameters for fieldbus communication are defined for the
controller. Lenze devices use codes for this purpose.

The codes of the controller and for communication are saved to the memory module in a
non-volatile data set.

In addition, there are codes for diagnosing and monitoring the stations.

Parameter reference

6.1 Before initial switch-on

 Stop!

Before switching on the controller for the first time, check ...

• the entire wiring for completeness, short circuit and earth fault.

• whether the bus system is terminated through a bus terminating resistor at
