15. 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 send data ready (TLC) 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.
