Pr.48 OPR retry
Set whether to carry out OPR retry.
When the OPR retry function is validated and the OPR is started, first the axis will
move in the OPR direction (1)). If the upper/lower limit switch turns OFF before the
near-point dog signal is detected (2)), the axis will decelerate to a stop, and then
will move in the direction opposite the OPR direction (3)). If it is detected that the
near-point dog signal has turned OFF while moving in the opposite direction, the
axis will decelerate to a stop (4)), and then will carry out OPR again (5), 6)).

[Operation for OPR retry function]
1) Movement in the OPR direction starts with the OPR start.
2) The axis decelerates when the limit switch is detected.
3) After stopping with the limit switch detection, the axis moves in the opposite direction of
the OPR at the OPR speed.
4) The axis decelerates when the near-point dog signal turns OFF.
5), 6) After stopping with the near-point dog signal OFF, carries out OPR in the OPR
direction.
