To enable the function "Automatic configuration" to assign the encoders to the drives, the
recommended rules below must be observed.
Recommended rules
● The DRIVE-CLiQ cable from the Control Unit must be connected as follows:
● The DRIVE-CLiQ connections between the power units must each be connected from
Figure 5-2
● The motor encoder must be connected to the associated power unit.

CLiQ line must be divisible by one another with an integer result. If the current controller
sampling time on a DO has to be changed to another pattern that does not match the other
DOs on the DRIVE-CLiQ line, the following options are available:
– Reconnect the DO to a separate DRIVE-CLiQ line.
– Also change the current controller sampling time and the sampling time of the inputs/
outputs of the DO not involved so that they again fit into the time grid.
Note
A Double Motor Module, a DMC20, and a TM54F each correspond to two DRIVE-CLiQ
nodes. This also applies to Double Motor Modules, of which just one drive is configured.
