Varispeed AC Protective Functions A ground fault with low resistance which occurs in motor cables or terminals. A ground fault occurs when the power is turned on. 17 : The ground fault here is one which occurs in the motor wiring while the motor is running. A ground fault may not be detected in the following cases. Display Meaning Fault PID Feedback Reference Lost (FBL) FBL Feedback Loss A PID feedback reference loss was detected (b5-12 = 2) and the PID feedback input was less than b5-13 (PID feedback loss detection level) for longer than the time set in b5-14 (PID feedback loss detection time).
