If executing the home position return (HPR) when selecting "0: Need to pass servo

motor Z-phase after power on" with the servo parameter of the servo amplifier

"Function selection C-4 (PC17)", it is necessary that the servomotor has been rotated

more than one revolution and passed the Z phase (Motor reference position signal)

and that the zero point pass signal ([Md.108] Servo status (low-order buffer memory

address): b0) has turned ON.

When selecting "1: Not need to pass servo motor Z-phase after power on" with

"Function selection C-4 (PC17)", it is possible to turn the zero point pass signal

([Md.108] Servo status (low-order buffer memory address): b0) ON without passing the

[Md.108] Servo status: b0

Data setting

To select the "HPR setting condition", set the "servo parameter" shown in the

1 : Not need to pass servo motor Z-phase

Precautions during operation

(1) Set "Function selection C-4 (PC17)", and then turn off the power supply of the
