Delta AL095 fault code meaning
Delta / AL095
Series: ASDA-E3, ASDA-E3C-E, ASDA-E3C-L
Regenerative resistor open or regenerative processing circuit error
servo drive
Meaning:
Possible causes
- The regenerative resistor capacity setting P1.053 is greater than 0, but no regenerative resistor is connected in the actual wiring.
- Regenerative energy processing circuit error.

External regenerative resistor open or regenerative transistor short circuit
servo drive
Meaning:
Possible causes
- The regenerative resistor connected to a power supply module rated 45 kW or below is open, or the regenerative transistor has a short circuit.
- The regenerative resistor capacity setting (P1.053) is greater than 0, but no regenerative resistor is connected in the actual wiring.
- Regenerative energy processing circuit error.
