[3] Precautions during control
(1) Absolute position system (ABS)
The INC motor is built-in the IAI electric actuator controlled by the IAI
electric actuator controller. The IAI electric actuator controller is not
compatible with the absolute position system.
Possible
(Operates artificially as the followings during
amplifier-less operation.
Servo amplifier type: MR-J4-10B, Motor type: HG-
