"OV3" occurs during an inverter stop.

FR-A044-0:With eight FR-A044-0.75KP units and four FR-A540-15K units, when the operation command is not input to all the FR-A044 units (during suspension), "OV3" occurs.
What are the possible cause and countermeasure?
Category : 


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).
