Chapter 8 OPR Control
8.4 Selection of the OPR setting condition
8.4.1 Outline of the OPR setting condition
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
zero point.
