Note
If an additional encoder is connected to a Motor Module, it is assigned to this drive as
encoder 2 in the automatic configuration.

Important!
All of the nodes on the DRIVE-CLiQ line must have the same sampling time in p0115[0]. otherwise
the VSM must be connected to a separate DRIVE-CLiQ interface on the Control Unit.
● Only one final node should ever be connected to free DRIVE-CLiQ ports of components
● If possible, Terminal Modules and Sensor Modules of direct measuring systems should
