Cause : HPFB bus timeout comes when there is no serial communication to the frequency converter’s communication option card.

  1. This warning will only be active when parameter 804 Bus timeout function is set to a value other thanOFF.
  2. If parameter 804 Bus timeout function is set to Stop and trip, it will first give a warning and then ramp down and trip out accompanied by an alarm.
  3. Parameter 803 Bus timeout can if required be increased.
