19.1.9 Determining the field angle on linear motors, torque motors and synchronous spindles
If an encoder was replaced that is also used to control a linear or torque motor or a synchronous
spindle, the commutation (position of the field angle) needs to be reset for this motor.
The method of defining the field angle of the respective axis / spindle is defined by the machine
manufacturer.
Follow the instructions of the machine manufacturer.
If only the scanning unit (AE) of an encoder was exchanged, the field-angle adjustment may not
be required.
