13.4 Connection to Kollmorgen drive controllers
This chapter contains the information for connecting STOBER synchronous servo motors to drive controllers
of the above-named manufacturer which differs from connecting to STOBER drive controllers. You can find
all other information about STOBER synchronous servo motors in the respective chapter of this catalog.
STOBER has taken the following measures to minimize the effort of commissioning STOBER motors con-
nected to Kollmorgen drive controllers and avoid errors during parameterization:
• The commutation offset of the motor was set so that calibration by the customer is not necessary.
• Parameter lists are provided on request.

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.
13.4.2 Possible combinations with drive controllers
The following table shows the possible combinations of STOBER synchronous servo motors with drive con-
trollers from Kollmorgen depending on the encoder model.
