E.PE
Parameter storage device fault (control circuit board)
Mitsubishi Electric · FR E700
What does E.PE mean?
An EEPROM fault, causing the inverter output to stop due to an error in the parameter storage (EEPROM fault) on the control circuit board. This often results from an excessive number of parameter write operations, potentially corrupting essential configuration data. Persistent issues may require expert intervention.
Complete Troubleshooting Guide
- 1
If parameters are being written frequently for communication purposes, set Pr. 342 to "1" to enable RAM write (note: RAM writes are volatile and revert on power cycle).
