Overview of Safety Integrated functions
1)
The encoderless Safety Extended Functions can be implemented only on
request for SINAMICS S120 chassis format units and cabinet units.
2)
Activation using terminals on the TM54F currently requires an encoder.
3)
Activation using terminals on the TM54F currently requires a license.
