13.6 Connection to Beckhoff 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 AX5000 drive controllers and avoiding errors during parameterization:
• The commutation offset of the motor was set so that calibration by the customer is not necessary.
• The electronic nameplate of the motor was designed to be compatible with the AX5000.
• Parameter files for all supported motor versions are available for download.
More information on commissioning EZ motors connected to Beckhoff AX5000 drive controllers can be
found in the 443185_en document in the download area on the STOBER website.

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