F535 12-pulse communication fault in ABB DCS800 drive indicates a 12-pulse communication fault. This fault occurs when there is a communication error between the two 6-pulse converters that make up a 12-pulse drive.

  1. Check 12P TimeOut (94.03)
  2. Check DCSLink cable connections
  3. Check DCSLink termination
  4. Check DCSLink node ID settings
