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
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
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.
