Delta AL0A1 fault code meaning
Delta / AL0A1
Series: ASDA-H3
Regenerative braking transistor overcurrent
servo drive
Meaning: Excessive regenerative energy causes the current through the regenerative braking transistor to exceed its allowable value.
Possible causes
- Condition: Excessive regenerative energy causes the current through the regenerative braking transistor to exceed its allowable value. Cause:
- Incorrect regenerative resistor selected.
- An excessive surge of other energy (such as interference) is fed back into the power supply module.
- Regenerative energy processing circuit error.
