E.RET

Retry Count Excess

Mitsubishi Electric · Mitsubishi FR-E800 Variable Frequency Drive

What does E.RET mean?

The inverter output is shut off because an automatic fault recovery attempt (retry) failed to resolve a preceding fault within the number of retries configured in Pr.67 Number of retries at fault occurrence. This means the underlying problem persists despite multiple attempts to restart, preventing the inverter from resuming normal operation.
