Cause : HPFB bus timeout comes when there is no serial communication to the frequency converter’s communication option card.
- This warning will only be active when parameter 804 Bus timeout function is set to a value other thanOFF.
- 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.
- Parameter 803 Bus timeout can if required be increased.
