7581 fault in ABB DCS880 drive indicates DDCS controller communication. This means cyclical communication between DDCS controller and drive is lost or there is no communication at all.

  1. Check the status/settings of the DDCS controller.
  2. Check the adapters between DDCS controller and drive.
  3. Check the setting of 20.01 Command location.
