Cause : Undervoltage comes when the power supply voltage of the converter decreases, the control circuit will not perform normal functions. To prevent this, the output of the converter is stopped when the power supply voltage drops to about 150 VAC or lower.
• Check if a high-capacity motor is driven.
• Check that the wiring is performed correctly.
