Inrush Current Limit Circuit Fault

Mitsubishi · FR-D700 Inverter (Basic)

What does Inrush current limit circuit fault mean?

The resistor of the inverter's inrush current limit circuit has overheated. This typically occurs due to frequent power cycling (ON/OFF) of the inverter, which causes the inrush current limiting components to work excessively, leading to thermal stress and potential failure. Overheating can degrade or destroy these components, preventing proper inverter startup.
