Cause : Power Supply Undervoltage comes when the input power supply voltage became equal to or lower than the Input Power Supply Undervoltage Detection Level.
1. 200 V Class: Approximately 150 Vac
2. 400 V Class: Approximately 300 Vac
- The power supply voltage is low.
- Increase the power supply voltage.
- A phase loss occurred in the input power supply.
- Check the input power supply for phase loss or an imbalance in the interphase voltages.
- Investigate and correct the cause and reset the fault.
