Inrush Current Limit Circuit Fault
Mitsubishi Electric · FR-D700 Basic Inverter
What does Inrush current limit circuit fault mean?
The resistor within the inrush current limit circuit has overheated, often as a result of frequent power ON/OFF cycles. This circuit is vital for protecting the inverter's main circuit from high currents during power-up. Overheating indicates a potential failure of this component, risking significant damage to the inverter's power stage.
