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

Data setting
To select the "HPR setting condition", set the "servo parameter" shown in the
following table.
Servo parameters are set for each axis.
The "HPR setting condition" is stored into the following buffer memory addresses.

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
valid.
