0 : Near-point dog method
(1) Start machine OPR.
(Start movement at the "
Pr.46
OPR speed
" in the "
Pr.44
OPR
direction
".)
(2) Detect the near-point dog ON, and start deceleration.
(3) Decelerate to "
Pr.47
Creep speed
", and move with the 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 home position return (OPR) has been
started, the zero point of the encoder must be passed
at least once before point A is reached.
However, if selecting "1: Not need to pass servo
motor Z-phase after power on" with "Function
selection C-4 (PC17)", it is possible to carry out the
home position return (OPR) without passing the zero
point.
