Retry count excess

What does E.RET mean?

This fault signifies that the inverter has attempted to automatically resume operation a specified number of times (configured in Pr. 67) after a previous fault, but has failed to clear the underlying problem. The inverter will now trip to prevent further damage. This code indicates a persistent issue that needs direct investigation and manual intervention.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Ensure Pr. 67 (Number of retries at fault occurrence) is set appropriately for the application, or '0' if automatic retries are not desired.

2. 4

   Once the underlying issue is resolved, manually reset the inverter.
