FF39
Power Off Required for Hardware Reconfiguration
ABB · ACS560 Standard Control Program Firmware
What does FF39 mean?
The inverter type (e.g., sr0025_3) has been changed, typically at the factory or during drive implementation, and a power cycle is required to validate this change. This alarm prompts the user to switch off the control board power to finalize the hardware reconfiguration and allow the drive to operate with the new settings.
