Transmission error
In the ABS transfer mode, the servo amplifier processes time-out below, and displays [AL. 0E5] when a time-out error occurs.
[AL. 0E5 ABS time-out warning] is canceled when ABSM changes from off to on.
• ABS request off-time time-out check (applied to 32-bit absolute position data in 2-bit units + checksum)
If the ABS request signal from the programmable controller is not turned on within 5 s after ABST is turned on, this will be
treated as a transmission error and [Al. 0E5 ABS time-out warning] occurs.
• ABS request on-time time-out check (applied to 32-bit absolute position data in 2-bit units + checksum)
If the ABSR is not turned off by the programmable controller within 5 s after ABST is turned off, this will be treated as a
transmission error and [AL. 0E5] occurs.
