Cautions
• A system which the servomotor can rotate one time or more is required.
• When a servomotor stops with specified condition enables and rotates to reverse direction one time after proximity dog ON,
make a system for which does not turn OFF the external upper/lower stroke limit.
• Keep the proximity dog ON during deceleration from the home position return speed to the creep speed. If the proximity
dog turns OFF before deceleration to the creep speed, a deceleration stop is made and the next zero point is set as the
home position.
• If home position return is executed in the proximity dog ON, it starts with the creep speed.
• When home position return retry function is not set, if home position return is executed again after home position return
completion, a minor error (error code: 197BH) will occur, the home position return is not executed.
• When "1: Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4
(PC17)" of servo parameter (expansion setting parameter), even if it does not pass zero point at the servo amplifier power
ON, the "[St.1066] Zero pass (R: M32406+32n/Q: M2406+20n)" turns ON. This operation is the same as proximity dog
method 1.
• If "[St.1062] In-position (R: M32402+32n/Q: M2402+20n)" does not turn ON, home position return is not ended.
