Mitsubishi Electric · FR-E500 Inverter

What does Corrupt Memory mean?

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.

Common Causes

  • Excessive number of parameter write times, exceeding the rated lifespan of the memory device.
  • Internal inverter hardware failure related to the parameter storage device.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1
