Servo parameter setting [G] [WG]

Set [Pr. PA03 Absolute position detection system] to "1" (enabled (absolute position detection system)).

Servo parameter setting [A]

Set [Pr. PA03 Absolute position detection system] to "1" (enabled (absolute position detection system by DIO)).

Homing

After the absolute position detection system is enabled, [AL. 025 Absolute position erased] occurs at the initial startup. Then,
ABSV (Absolute position undetermined) turns on. Refer to "CONTROL MODE" in the following manual and perform homing.
