Delta AL056 fault code meaning
Delta / AL056
Series: ASDA-A3, ASDA-E3
Motor speed too high
servo drive
Meaning: When the motor speed (after filtering) exceeds the setting of P1.111, the servo drive immediately switches to the Servo Off status and displays this alarm.
Possible causes
- Condition: When the motor speed (after filtering) exceeds the setting of P1.111, the servo drive immediately switches to the Servo Off status and displays this alarm. Cause: This alarm primarily alerts the user that the motor speed has reached the currently set upper limit (P1.111).

Motor speed too high
servo drive
Meaning: When the filtered motor speed exceeds the setting in P1.111, the servo drive immediately switches to the ServoOff status and displays this alarm.
Possible causes
- Condition: When the filtered motor speed exceeds the setting in P1.111, the servo drive immediately switches to the ServoOff status and displays this alarm. Cause: This alarm primarily alerts the user that the motor speed has reached the upper limit (the setting in P1.111).

Series: ASDA-W3
Motor speed too high
servo drive
Meaning: Monitored variable 7 [Speed feedback (0.1 rpm)] > P1.111.
Possible causes
- Condition: Monitored variable 7 [Speed feedback (0.1 rpm)] > P1.111. Cause
- The P1.111 setting is too small.
- Incorrect command parameter settings cause the command speed to be too high.
- The control gain parameter settings are too high, causing system divergence.
- Encoder feedback error.
- Check whether interference is causing the pulse encoder to miss pulses.
- The third-party motor encoder resolution setting PM.004 is incorrect.
