Answer
It depends on the setting of servo parameter "[PA03] Absolute position detection system" whether the HPR request flag ("[Md.31] Status": b3) turns ON or not.
The flag turns ON in the following cases:
(1) "1: Enabled (absolute position detection system)"
• When the machine HPR has not been executed at the absolute position system
• When a machine HPR operation starts
• When the absolute system has not been set
• When "[PA14] Rotation direction selection/travel direction selection" is changed
(2) "0: Disabled (incremental system)"
• System's power supply on or reset
• Servo amplifier power supply on
• Machine HPR start
