Danfoss · VLT HVAC Drive FC 102
The frequency converter's parameter settings have been reset to their factory default values, typically after a manual reset action. This alarm serves as a notification that custom configuration has been lost. The drive will operate with default parameters until reconfigured, potentially affecting application performance and safety.
Click steps to track your progress.
1. Check parameter P14-22 (Initialization) status to confirm if a factory reset was intentionally performed.
2. Reload the last known good parameter backup file from a PC tool (e.g., MCT10) or saved LCP settings.
3. Manually reconfigure all necessary application-specific parameters, paying close attention to critical motor and control settings.
4. If the fault persists after reconfiguring, try updating the drive's firmware to the latest stable version.
