1.
Start machine OPR. (Start movement at the "[Pr.46] OPR speed" in the "[Pr.44] OPR direction".)
2.
The machine begins decelerating when the near-point dog ON is detected.
3.
The machine decelerates to the "[Pr.47] Creep speed", and subsequently moves at that speed. (At
this time, the near-point dog must be ON. If the near-point dog is OFF, the machine will decelerate
to a stop.)
4.
At the first zero signal (one pulse output at one motor revolution) after the near-point dog OFF, the
pulse output from the LD75 stops, and the machine OPR is completed.

After decelerating at the near-point dog ON, stop at the zero signal and complete the machine OPR.
After decelerating at the near-point dog ON, stop with the stopper, and complete the machine OPR after the
dwell time has passed.
After decelerating at the near-point dog ON, stop with the stopper, and complete the machine OPR with the
zero signal.
After starting with the creep speed, stop with the stopper, and complete the machine OPR with the zero
signal.
After decelerating at the near-point dog ON, move the designated distance, and complete the machine OPR
with the zero signal.
After decelerating at the near-point dog ON, move the designated distance, and complete the machine OPR.
