8 OPR CONTROL
Restrictions
(1) Always limit the motor torque.
If the torque is not limited, the motor may fail when the machine presses
against the stopper.
(For a torque limit, refer to the manual of the drive unit used.)
(2) Use an external input signal as the zero signal.
Precautions during operation
(1) If the zero signal is input before the workpiece stops at the stopper, the
workpiece will stop at that position, and that position will become the OP.
