(d) 3: Stopper method 3)
1.
Start machine OPR. (Start movement at the "[Pr.47] Creep speed" in the "[Pr.44] OPR direction". At
this time "[Pr.54] OPR torque limit value" is required. If the torque is not limited, the servomotor
could be damaged in step 2.)
2.
The machine contacts against the stopper at "[Pr.47] Creep speed", and then stops.
3.
After stopping, the pulse output from the LD75 stops with the zero signal (signal that is output on
detection of contact with the stopper. Input externally), and the machine OPR is completed.
(e) 4: Count method 1)
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.
4.
After the near-point dog turns ON and the movement amount set in "[Pr.50] Setting for the
movement amount after near-point dog ON" has passed, the pulse output from the LD75 stops
with the first zero signal (one pulse output at one motor revolution), and the machine OPR is
completed.
