(3) If the "
Pr.49
OPR dwell time" elapses before the stop at the stopper, the workpiece
will stop at that position, and that position will be regarded as the OP.
At this time, an error will not occur.

(4) The near-point dog must be turned ON until it presses against the stopper. If any
range that the near-point is turned OFF exists until it presses against the stopper,
executing the machine OPR from the area leads it to be pressed against the stopper
at OPR speed.
(5) Machine OPR started while the near-point dog is ON will start at the "
Pr.47
Creep
speed".
(6) When a machine OPR is stopped with the stop signal, perform a machine OPR again.
If the restart command is turned ON after a stop with the stop signal, an error "OPR
restart not possible" (error code: 209) occurs.
