Parameter storage device fault

Parameter Storage Device Fault

Mitsubishi · FR-D700 Inverter (Basic)

What does Parameter storage device fault mean?

An abnormality has occurred in the component (control circuit board) where parameters are stored. This suggests a hardware issue with the inverter's non-volatile memory, potentially leading to incorrect operation, loss of critical settings, or failure to save new parameters. Frequent parameter writes for communication purposes can stress this component.

Complete Troubleshooting Guide

  1. 1

    If frequently writing parameters via communication, set Pr. 342 to '1' to enable RAM write (note that parameters written to RAM will revert on power-off).

  2. 2

    If the fault persists or is not related to frequent writes, contact your sales representative for further diagnosis or repair of the control circuit board.
