3.11 Encoder mounting arrangements
Replacing encoders For 1-encoder systems, it is advisable to replace the entire motor in the case of
a defect in the motor measuring system (indirect measuring system).
!
The user can suppress the automatic, internal actual value check by resetting
the "User agreement" and thus request re-calibration of the axis with user
agreement.
