EPM data: unknown parameter found

Hva betyr 0x7696 ?

The memory module (EPM) contains parameter settings that are not recognized by the current inverter software. This can happen after firmware updates or compatibility changes.

• Firmware version of the inverter is older than the firmware version used to save parameters to the EPM, resulting in unrecognized new parameters.
• A firmware update on the inverter changed or removed certain parameters, and the EPM still holds values for these outdated parameters.
• The EPM module was used with a different drive model or series that has a distinct parameter set, leading to foreign parameter entries.
• Data corruption on the EPM module, causing invalid parameter addresses or values to be stored.
• Improper parameter saving process, potentially leading to incomplete or corrupted data on the EPM.

1. 1

   Connect to the inverter with the configuration software and upload parameters from the EPM to identify the 'unknown' parameters if possible.

2. 2

   Update the inverter's firmware to the latest available version. Then perform a parameter initialization (e.g., P99.00 = 1) and reconfigure parameters.

3. 3

   If a known good and compatible EPM is available, try swapping it to see if the fault clears.

4. 4

   Perform a factory reset of the inverter (e.g., P99.00 = 1) to ensure all parameters are at default values, then re-enter application-specific settings.

5. 5

   Manually review and compare the parameter list from the EPM (if readable) with the current inverter's parameter manual to pinpoint discrepancies.
