• If the time set in [Pr.49] OPR dwell time elapses before stopping at the stopper, the workpiece will stop at that position, and
the position will be set as an OP. In this case, no error will occur.

• The near-point dog must be on until the workpiece hits the stopper. If there is a section in which the near-point dog is off
between the near point dog and the stopper, and a machine OPR operation is executed from a point in the section, the
workpiece will hit the stopper at the OPR speed.
• If the machine OPR is started while the near-point dog is on, the workpiece starts traveling at the speed set in [Pr.47] Creep
speed.
• When the machine OPR has been stopped by a stop signal, perform the machine OPR again. If the restart command is
turned ON after the stop by a stop signal, OPR restart not possible (Error code: 1946H) occurs.
