F516 fault in ABB DCS880 drive indicates M1 field exciter communication. This means motor 1 field exciter loss of communication.

  1. Check the settings of 99.07 M1 used field exciter type and 70.12 Field exciter timeout.
  2. Check the auxiliary voltage for integrated and external field exciter.
  3. Check the DCSLink cable connections.
