15. ABSOLUTE POSITION DETECTION SYSTEM
15.7.2 Transfer method
The sequence in which the base circuit is turned ON (servo-on) when it is in the OFF state due to the
servo-on (SON) going OFF, an emergency stop (EMG), or alarm (ALM), is explained below. In the
absolute position detection system, every time the servo-on (SON) is turned on, the ABS transfer mode
(ABSM) should always be turned on to read the current position in the servo amplifier to the controller.
The servo amplifier transmits to the controller the current position latched when the ABS transfer mode
(ABSM) switches from OFF to ON. At the same time, this data is set as a position command value inside
the servo amplifier. Unless the ABS transfer mode (ABSM) is turned ON, the base circuit cannot be
turned ON.
