Retry Count Excess

What does Retry count excess mean?

The inverter has failed to restart within the set number of retries after a preceding error or trip. This indicates a persistent underlying problem that the inverter's automatic recovery attempts could not resolve, requiring manual intervention to prevent further issues.

• Persistent underlying fault (e.g., overcurrent, overvoltage) that the inverter repeatedly attempts to clear without success.
• Autorestart attempts (Pr. 136) set too high while the root cause of the initial trip remains unaddressed.
• Mechanical problem (e.g., sticky brake, high friction load) that prevents successful motor restart.
• Instability in the power supply causing repetitive short-duration trips.
• Inadequate delay time (Pr. 137) between retry attempts, not allowing enough time for conditions to normalize.

Click steps to track your progress.

1. 1

   Identify and resolve the initial fault code that triggered the retries (check fault history, e.g., Pr. 093, Pr. 094).

2. 2

   Reduce the number of autorestart attempts (Pr. 136) to 0 or a low value for diagnostic purposes.

3. 3

   Increase the autorestart delay time (Pr. 137) to allow more time for system recovery between attempts.

4. 4

   Inspect the mechanical load for any binding or issues that would prevent a smooth restart (e.g., manually rotate the shaft).

5. 5

   Monitor the incoming power supply voltage for stability and transient events using a power quality analyzer.
