(3) 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 ORR speed.
(4) Machine OPR started while the near-point dog is ON will start at the "
speed".
(5) 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.
