In Lexium range drive the permissible range of motor shaft movement if absolute position is to be retained while servo drive is powered off.
Permissible range of motor shaft movement is +/ - 0.25 revolution from the position at which motor shaft position was
at the moment servo drive was powered OFF. If movement of motor shaft crosses this limit while servo drive is powered OFF,
upon re-applying power to servo drive, servo drive will trip on fault code E 734C that indicates that absolute position of motor
shaft detected is not with in permissible range.
