(1) Start machine OPR.
(Start movement at the "

"
OPR direction".)
(2) Detect the near-point dog ON, and start deceleration.

(3) Decelerate to "
creep speed.
(At this time, the near-point dog must be ON. If the near-
point dog is OFF, the axis 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 QD75 stops, and the machine OPR is completed.
