0 : Proximity dog method [RJ010 mode]
(1) Start machine HPR.
(Start movement at the "[Pr.46] HPR speed" in the "[Pr.44]
HPR direction".)
(2) Detect the proximity dog ON, and start deceleration.
(3) Decelerate to "[Pr.47] Creep speed", and move with the
creep speed.
(At this time, the proximity dog must be ON. If the proximity
dog is OFF, the axis will decelerate to a stop.)
(4) At the first zero signal after the proximity dog turned OFF,
machine HPR is completed.
Note) After the home position return (HPR) 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 (HPR) without passing the zero
point.

4 : Count method 1) [RJ010 mode]
(1) Start machine HPR.
(Start movement at the "[Pr.46] HPR speed" in the "[Pr.44]
HPR direction".)
(2) Detect the proximity dog ON, and start deceleration.
(3) Decelerate to "[Pr.47] Creep speed", and move with the
creep speed.
(4) After the proximity dog turns ON and the movement amount
set in "[Pr.50] Setting for the movement amount after
proximity dog ON" has passed, the Simple Motion module
stops with the first zero signal, and the machine HPR is
completed.
Note) After the home position return (HPR) 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 (HPR) without passing the zero point.

The proximity dog must turn OFF
at a sufficient distance away from
the HP.

(4) After the proximity dog turns ON and the movement amount
set in "[Pr.50] Setting for the movement amount after
proximity dog ON" has passed, machine HPR is completed.
