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.
The ABS communication error occurs if the ABS time-out warning (AL.E5) is generated at the servo
amplifier due to an ABS request OFF time time-out.
