Delta AL048 fault code meaning
Delta / AL048
Series: ASDA-A3, ASDA-B3, ASDA-H3
OA and OB output error
servo drive
Meaning: The output pulse frequencies of OA and OB exceed the maximum hardware output frequency.
Possible causes
- Condition: The output pulse frequencies of OA and OB exceed the maximum hardware output frequency. Cause:
- The output pulse resolution settings for OA and OB are too high.
- Noise interference on the encoder signal cable or cable damage causes a communication error.
- Encoder error.

Series: ASDA-E3
Position detector output error
servo drive
Meaning: The detector output pulse frequency exceeds the maximum hardware output frequency.
Possible causes
- Condition: The detector output pulse frequency exceeds the maximum hardware output frequency. Cause:
- The detector pulse resolution setting is too high.
- Noise interference affecting the encoder cable or cable damage causes a communication error.
- Encoder error.
