(1) Start machine OPR.
(Start movement at the "
Pr.44
" 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 after the near-point dog turned OFF,
machine OPR is completed.
Note) After the servo amplifier turned on, the zero point of
the encoder must be passed at least once before
point A is reached.
