Avoiding Nuisance Err03 Trips in FST-650L VFD-Driven Air Compressors through Proper Freq-to-Mains Switching Logic

Learn how a 75 kW FST-650L VFD eliminated nuisance Err03 over-current trips by optimizing frequency-to-mains switching logic—coast-stop, zero-current interlock and timing diagram included.

75 kW VFD Driving a Fan Trips on Overcurrent at Higher Frequencies

A chemical plant’s 75 kFD driving a 55 kW fan kept tripping “OC” above 30 Hz. Investigation showed a 45 kW control board had been fitted; current-sensing scale was wrong. Re-installing the correct 75 kW board and re-tuning parameters eliminated the nuisance trip.
