Internal fault (Application-oriented control cannot recognize EEPROM data)
Danfoss · VLT HVAC Drive High Power
¿Qué significa 515 ?
The application-oriented control system cannot recognize the EEPROM data. This indicates an incompatibility or corruption in the stored application parameters.
Causas comunes
- Incompatibility between the currently loaded application firmware version and the format of the stored EEPROM data.
- Corruption of application-specific parameters within the EEPROM, rendering them unreadable or invalid for the control logic.
- A partial or failed firmware update that resulted in a mismatch between the application code and the EEPROM data structure.
- Attempting to load parameters from a different frequency converter model or a significantly different firmware version.
- Failure of the frequency converter's internal data integrity check during application startup, indicating malformed data.

- 1
1. Verify the frequency converter's firmware version and ensure it is compatible with the expected application data.
- 2
2. Perform a factory reset (e.g., Parameter P14-22 Load defaults) to initialize the EEPROM with default, recognizable data.
- 3
3. Re-download the correct application parameters from a known good backup file that matches the frequency converter's model and firmware.
- 4
4. If a firmware update was recently performed, consider reverting to the previous stable firmware version if possible.
- 5
5. Check for any physical configuration switches or jumpers on the control board that might affect application loading or memory mapping.
