Delta AL06B fault code meaning
Delta / AL06B
Series: ASDA-A3
Difference between drive internal coordinates and encoder coordinates too large
servo drive
Meaning: While the absolute motor is powered by the battery, the motor rotation turn count exceeds half the turn-count resolution.
Possible causes
- Condition: While the absolute motor is powered by the battery, the motor rotation turn count exceeds half the turn-count resolution. Cause: The difference between the drive's internal coordinates and the encoder coordinates is too large.

Series: ASDA-B3, ASDA-E3C-E, ASDA-H3
Difference between drive internal coordinates and encoder coordinates too large
servo drive
Meaning: When the absolute motor is powered by the battery, the rotation turn count exceeds one quarter of the turn count resolution.
Possible causes
- Condition: When the absolute motor is powered by the battery, the rotation turn count exceeds one quarter of the turn count resolution. Cause: The difference between the drive's internal coordinates and the encoder coordinates is too large.

Series: ASDA-E3
Difference between drive internal coordinates and encoder coordinates too large
servo drive
Meaning: When the absolute motor is powered by the battery, the number of revolutions exceeds half the revolution count resolution.
Possible causes
- Condition: When the absolute motor is powered by the battery, the number of revolutions exceeds half the revolution count resolution. Cause: The difference between the drive's internal coordinates and the encoder coordinates is too large.

Series: ASDA-W3
Excessive movement of the absolute motor after power-off caused an absolute position error.
servo drive
Meaning: After the drive power supply was turned off, the absolute linear motor moved beyond the range permitted by the servo.
Possible causes
- Condition: After the drive power supply was turned off, the absolute linear motor moved beyond the range permitted by the servo. This alarm occurs immediately at the next power-on. Cause:
- Absolute encoder signal error.
