The motor measurement system is used for sensing the motor position. A se-
cond measuring system, e.g. a scale, can be used for load-side position
sensing if necessary.
Incremental encoders, distance-coded incremental encoders, or EnDat absolute
value encoders can be used (voltage signals).
M: Max. possible measuring steps
G: Accuracy of the encoder
