"OV3" occurs during an inverter stop.

What are the possible cause and countermeasure?

Answer

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 cause is a power surge, it can be improved by installing the AC reactor (FR-HAL).
