Cause : Input power supply fault 1 comes when a fault is detected in the power supply frequency or the phase detection cannot be performed for the normal power supply.
- When an overvoltage occurs during power failure or at an input phase loss.
- When the power supply amplitude changes suddenly
- Check that the wiring from proper power source is performed correctly.
