F534 fault in ABB DCS880 drive indicates 12-pulse current difference. This means the current of difference of a 12-pulse parallel configuration exceeded the current difference level.

  1. Check the settings of 29.17 12-pulse parallel current difference level and 29.18 12-pulse parallel current difference delay.
  2. Check the settings of the current controller in group 27 Armature current control.
