HW RECONF RQ

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.

• 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.

Click steps to track your progress.

1. 1

   Acknowledge the 'HW RECONF RQ' alarm and wait for the subsequent 'POWEROFF!' (FF39) alarm to activate.

2. 2

   Switch the control board power of the ABB ACS800 drive off completely using the main disconnect.

3. 3

   Power on the control board again to allow the drive to validate the inverter type change and reconfigure its hardware settings.

4. 4

   Verify that the inverter type shown in the drive's monitoring parameters matches the physical unit after the power cycle.
