Encoder system connection
Description
The Sensor Modules evaluate the signals from the connected motor encoders or external
encoders and convert the signals so that they can be evaluated by the Control Unit. The
encoder system can only be connected to SINAMICS via DRIVE-CLiQ. The following rule
applies: Motor encoders are connected to the associated Motor Module, external encoders
are connected to the Control Unit. In conjunction with motor encoders, the motor
temperature can also be evaluated using Sensor Modules.
Sensor Modules Cabinet (SMC) are intended for internal cabinet installation.
