What does FF38 mean?
The inverter type (e.g., sr0025_3) of the ABB ACS800 drive has been changed, typically during factory setup or drive implementation. This alarm indicates that the new inverter hardware configuration needs to be validated by a power cycle of the control board.
Common Causes
- A change in the inverter type or configuration has been detected by the drive's system.
- New hardware components requiring re-initialization have been installed or configured.
