Fault display

"E.OV3" is displayed when the voltage between the inverter terminals PN rises abnormally high while the inverter is decelerating or stopped. In this case, th... More Details >>

"OV3" occurs during an inverter stop.

An error may have occurred due to the rise of the main circuit voltage of the inverter caused by a power surge. Check for the power supply voltage. If the ca... More Details >>
