of all axes OFF.
— —
Do not request the start when the axis operation state is other
than "standby", "stop", and "step standby".
105 —
Review the content of the positioning or "[Pr.96] Operation
cycle setting" longer than the current setting.

<HPR retry>
0, 1
• Validate the HPR retry function (set value: 1). (Refer to
Section 13.2.1).
• Move the work piece from the current position (on HP) using
the manual control operation (refer to Chapter 11), then carry
out a machine HPR again.

<Movement amount setting after proximity
dog ON>
0 to 2147483647
• Calculate the movement distance using a speed limit, HPR
speed, and deceleration time, and set the movement amount
after proximity dog ON so that the distance becomes a
deceleration distance or longer.
• Lower the HPR speed.
• Adjust the proximity dog position so that the movement
amount after proximity dog ON becomes longer. (Refer to
Section 8.2.4, 8.2.5)

to Section 8.2)
4300+100n
<Positioning start No.>
1 to 600, 7000 to 7004, 9001 to 9004
Start the machine HPR (positioning start No. 9001) again.
(Refer to Section 8.2)
— —
Turn the motor more than one revolution using JOG or
positioning operation.
— —
• Execute HPR again.
• When the servo parameter "Function selection C-4 (PC17)"
is changed to "1: Not need to pass motor Z-phase after the
power supply is switched on", transfer the parameter from
the Simple Motion module to the servo amplifier and turn the
power supply of the servo amplifier OFF. Then, turn it ON
and execute HPR again.
— —
• Execute HPR again.
• Adjust the servo gain and in-position range, and execute
HPR again.
