Mitsubishi Electric · FR-E500 Inverter
A fault has occurred in the inverter's parameter storage device, such as an E2PROM fault. This indicates an issue with the non-volatile memory that stores inverter parameters, potentially leading to lost or corrupted settings.
Click steps to track your progress.
Perform a power cycle by switching the inverter's power supply off, waiting for at least 10 seconds, and then switching it back on.
If the fault persists, contact a sales representative for further diagnosis or potential inverter replacement due to a critical internal memory failure.
