Internal Fault: Parameter value out of limits

Was bedeutet 38.783 ?

An internal parameter's stored value has fallen outside its predefined minimum or maximum allowable range. This can be caused by data corruption, an incorrect parameter write, or a software anomaly, leading to unexpected drive behavior or shutdown.

• Data corruption in the drive's non-volatile memory storing parameter values.
• A firmware bug that attempts to write or read a parameter with an invalid value.
• Manual attempt to set a parameter value outside its predefined min/max range via LCP or fieldbus (though usually prevented).
• Faulty control board memory module or processing unit allowing invalid data states.

1. 1

   1. Cycle power to the frequency converter to force a re-initialization of internal parameter registers.

2. 2

   2. Perform a parameter initialization (P14-22 set to '2') to revert all parameters to factory defaults.

3. 3

   3. Reload a known good parameter backup from a saved configuration file or a different drive.

4. 4

   4. Update the drive's firmware to the latest available version, as this can resolve known parameter handling bugs.
