Retry No Over

Retry count exceeded

Mitsubishi Electric · FR-E500 Inverter

What does Retry No Over mean?

This function stops the inverter output because operation could not be resumed properly within the configured number of retries. This fault indicates that a preceding error condition repeatedly occurred, and the inverter's auto-retry attempts were unsuccessful.

Common Causes

  • Persistent underlying fault that the inverter attempts to clear through retries (e.g., recurring overcurrent, undervoltage).
  • Incorrect setting of retry parameters, leading to an insufficient number of retries or inappropriate retry conditions.
  • External conditions (e.g. fluctuating power, mechanical load issues) that repeatedly trigger minor faults.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Identify and eliminate the cause of the preceding alarm or error indication that led to the retry attempts.

  2. 2

    Review the inverter's fault history to determine the specific fault that is repeatedly occurring before the 'Retry No Over' fault.

  3. 3

    Adjust the retry parameters (if applicable) to better suit the application, ensuring sufficient retries for transient faults but not masking persistent issues.
