Hva betyr FF39 ?
This alarm indicates that the inverter type (e.g., sr0025_3) of the ABB ACS800 drive has been changed, usually at the factory or during drive implementation. It requires a complete control board power cycle to validate the new configuration and apply the changes. This fault typically activates after an 'HW RECONF RQ' (FF38) alarm.
Vanlige årsaker
- An inverter type change has been detected, and the system requires a power cycle to apply and validate the new hardware configuration in the drive.
- New hardware components requiring re-initialization have been installed or configured.

Ensure all necessary actions related to the preceding 'HW RECONF RQ' (FF38) alarm have been performed.
- 2
Switch the control board power of the ABB ACS800 drive off completely using the main disconnect switch.
- 3
Power on the control board again to allow the drive to validate the inverter type change and complete its internal hardware reconfiguration.
- 4
Confirm that the fault clears and the drive operates normally after the power cycle, and verify the inverter type shown in drive parameters matches the physical unit.
