6) High Bus Fault. This is a common fault in VFDs. It is normally caused by external factors such as when there is an instantaneous spike in the AC line voltage or when the machine''s inertia creates an overhauling load. This load continues to rotate faster than the motor''s recommended speed, causing the VFD to take protective measures.
Film Capacitors Just like MLCCs, film-CAPs are non-polar devices and have somewhat similar layered structure. In this case the dielectric layer, polymer film typically polypropylene (others include polystyrene, polycarbonate, etc.) …
