Cause : Phase loss comes when the drive is not detecting all three phases of the incoming AC power supply. This means the drive has detected a missing or abnormal voltage level on one of the three input phases (typically L1, L2, and L3) that supply power to the drive.
The PHL warning in Delta drive indicates an Input Phase Loss. This means that the drive is not detecting all three phases of the incoming AC power supply.
- Verify the wiring of the main circuit.
- Use the model with voltage that matches the power.
- Check if the input cable of three-phase power is broken.
- Make sure the wiring is correct.
- Replace the broken part of the cable.
