80

Drive initialised to default value

Danfoss · VLT HVAC Drive FC 102

What does 80 mean?

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.

Common Causes

  • Manual factory reset performed via LCP menu (e.g., P14-22 set to '2' or '10') or a dedicated reset button.
  • A severe internal memory error or corrupted parameter block requiring the drive to revert to safe defaults.
  • Firmware update procedure initiated without first saving existing parameter sets, leading to default values.
  • Loss of backup battery power (if applicable) for non-volatile memory in older drive models.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    1. Check parameter P14-22 (Initialization) status to confirm if a factory reset was intentionally performed.

  2. 2

    2. Reload the last known good parameter backup file from a PC tool (e.g., MCT10) or saved LCP settings.

  3. 3

    3. Manually reconfigure all necessary application-specific parameters, paying close attention to critical motor and control settings.

  4. 4

    4. If the fault persists after reconfiguring, try updating the drive's firmware to the latest stable version.
