    14. ABSOLUTE POSITION DETECTION SYSTEM (c) To detect the ABS time-out warning (AL.E5) at the servo amplifier, the time required for the ABS request signal to go OFF after it has been turned ON (ABS request time) is checked. If the ABS request remains ON for longer than 1s, it is regarded that an fault relating to the ABS request signal or the ABS transmission data ready (ABST) has occurred, and the ABS communication error is generated.

    14. ABSOLUTE POSITION DETECTION SYSTEM (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, or alarm, is explained below. In the absolute position detection system, always give the serial communication command to read the current position in the servo amplifier to the controller every time the ready (RD) turns on.
