Pr.50 Zero point return retry
Set whether to carry out zero point return retry.
When the zero point return retry function is validated and the machine zero point
return is started, first the axis will move in the designated zero point return
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 designated zero point return 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 machine
zero point return again (5), 6)).

Zero point signal
[Operation for zero point return retry function]
1) Movement in the designated zero point return direction starts with the machine zero point
return 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 designated zero point return direction at the zero point return 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 machine zero point
return in the designated zero point return direction.
