Drive initialised to default value

What does ALARM 80 mean?

The frequency converter's parameter settings have been reset to their factory default values, typically following a manual reset operation. This means all previous application-specific configurations are lost, and the drive will operate with generic settings.

• User intentionally initiated a manual factory reset (e.g., via parameter P14-22 or specific button sequence).
• Control card replaced or firmware updated, which often defaults parameters as part of the process.
• Internal non-volatile memory error (e.g., EEPROM corruption), causing parameter loss and subsequent default loading.
• Extended power loss to the control card's backup power, causing volatile memory loss (less common with modern drives).
• Error during parameter upload/download via PC software, leading to a corrupt or incomplete parameter set.

Click steps to track your progress.

1. 1

   Confirm if a factory reset (e.g., P14-22 = 1 or 2) was intentionally performed or accidentally triggered.

2. 2

   Reload the last known good parameter set from a backup (e.g., using LCP copy/paste function or PC software tool).

3. 3

   Manually re-enter all necessary application-specific parameters, paying close attention to motor data (P1-20 to P1-25).

4. 4

   After re-entering parameters, perform an Automatic Motor Adaptation (AMA) to optimize motor control.

5. 5

   Check the control card's error log (if available) for any underlying internal faults that might have triggered the reset.
