Every CUD (both Standard CUD as well as also Advanced CUD) can evaluate the signals of an incremental encoder. For applications where more than one encoder must be evaluated, either a second CUD and/or the SMC30 Sensor Module Cabinet-Mounted can be used.

The SMC30 can be used to evaluate SSI encoders with incremental signals, which for instance, are used for positioning functions.

Encoders, which have a DRIVE-CLiQ interface, cannot be evaluated at the SINAMICS DC MASTER or at the SMC30. These encoders are usually not used in the DC drive technology.

The following encoder signals can be evaluated:

• Incremental encoders TTL/HTL with and without broken cable detection (broken cable detection is only available with bipolar signals)
• SSI encoder with TTL/HTL incremental signals
• SSI encoder without incremental signals

The motor temperature input, available on the SMC30, is not evaluated for SINAMICS DC MASTER. A motor temperature sensor can be evaluated using the temperature measurement input provided on each CUD.
