Retry count excess

What does E.RET mean?

This fault indicates that the inverter could not resume operation properly within the programmed number of retries (set by Pr. 67). It signifies a persistent underlying problem that prevents automatic recovery, leading to the inverter tripping after multiple failed attempts. The root cause of the initial fault must be identified and corrected.

1. 1

   Investigate and eliminate the primary cause of the fault that continuously triggered the retry attempts.

2. 2

   Review Pr. 67 setting to understand the retry parameters, although the focus should be on resolving the initial fault.
