Setting item

Function selection C-4

: Refer to Section 5.2.8 "Servo parameters" for information on the storage details.

If executing the home position return (OPR) 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

To select the "OPR setting condition", set the "servo amplifier" shown in the

following table.

Servo parameters are set for each axis.

The "OPR setting condition" is stored into the following buffer memory addresses.

0 : Need to pass servo motor Z-phase after

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

servo amplifier once and switch it on again to make that parameter setting
