[Pr.48] HPR retry [RJ010 mode]
Set whether to carry out HPR retry.
When the HPR retry function is validated and the machine HPR is started, first the
axis will move in the HPR direction (1)). If the upper/lower limit signal turns OFF
before the proximity dog signal ON is detected (2)), the axis will decelerate to a
stop, and then will move in the direction opposite the HPR direction (3)). If the
following edge of the proximity dog signal is detected during movement in the
opposite direction, the axis will decelerate to a stop (4)), and then will carry out
machine HPR again (5), 6)).
