Notes
• The encoder code is a part of the type designation of the motor.
• FMA = Version with fault exclusion for mechanical coupling.
• Multiple revolutions of the motor shaft can be recorded only using multi-turn encoders.
13.3.3 Possible combinations with drive controllers
The following table shows the possible combinations of STOBER synchronous servo motors with drive con-
trollers from Siemens depending on the encoder model.
Encoders with an EnDat 2.2 interface can be connected to Siemens S120 drive controllers and operated us-
ing the EIB 3392S interface.
