Delta AL08B fault code meaning
Delta / AL08B
Series: ASDA-A3, ASDA-B3, ASDA-E3, ASDA-E3C-E, ASDA-H3
Stop time too short for auto gain adjustment
servo drive
Meaning: When the auto tuning procedure is entered and the host controller is selected as the command source, the stop time planned by the host controller is too short. If the stop time is too short, the auto tuning algorithm cannot make a determination, affecting the tuning results.
Possible causes
- Condition: When the auto tuning procedure is entered and the host controller is selected as the command source, the stop time planned by the host controller is too short. If the stop time is too short, the auto tuning algorithm cannot make a determination, affecting the tuning results. Cause: The stop time within the cycle is too short.

Series: ASDA-W3
Auto gain tuning command duration too long or command stop time too short
servo drive
Meaning: When the auto tuning procedure is entered and the host computer is selected as the command source: 1. The unidirectional motion command duration exceeds 20 seconds. 2. Command stop time < 1 seconds. (If the stop time is too short, the auto tuning algorithm cannot make a determination, affecting the tuning results.)
Possible causes
- Condition: When the auto tuning procedure is entered and the host computer is selected as the command source
- The unidirectional motion command duration exceeds 20 seconds.
- Command stop time < 1 seconds. (If the stop time is too short, the auto tuning algorithm cannot make a determination, affecting the tuning results.) Cause: Command planning does not meet specifications.
