Cause : PI Feedback Loss comes when PI Feedback Loss detection is programmed to fault (b5-12 = 2) and the PI Feedback < PI Feedback Loss Detection Level (b5-13) for the PI Feedback Loss Detection Time (b5-14).Â
- PI Feedback source (e.g. transducer, sensor, building automation signal) is not installed correctly or is not working.
- Verify Drive is programmed to receive the PI Feedback source signal.
- Check to ensure the PI Feedback source is installed and working properly.
