6 : Data set method [RJ010 mode]
The position where the machine HPR has been made will be the HP.
(Perform after the servo amplifier has been turned ON and the servomotor has been rotated at least once using the
JOG or similar operation. 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.)
7 : Scale origin signal detection 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) After deceleration stop, it moves in the opposite direction
against of HPR at the "[Pr.46] HPR speed".
(4) During movement, the machine begins decelerating when
the first zero signal is detected.
(5) After deceleration stop, it moves in direction of HPR at the
speed set in "[Pr.47] Creep speed", and stops at the
detected nearest zero signal to complete the machine HPR.

[Pr.44] HPR direction
Set the direction to start movement when starting machine HPR.
0: Positive direction (address increment direction)
Moves in the direction that the address increments. (Arrow 2))
1: Negative direction (address decrement direction)
Moves in the direction that the address decrements. (Arrow 1))
Normally, the HP is set near the lower limit or the upper limit, so "[Pr.44] HPR
direction" is set as shown below.

When the zero point is set at the lower
limit side, the HPR direction is in the
direction of arrow 1).
