If Pb.08 is set to be 0, the trip-free function is invalid.
Trip-free function enables the inverter to perform low-voltage compensation when DC bus
voltage drops below Pb.07. The inverter can continue to run without tripping by reducing
its output frequency and feedback energy via motor.
Notice: If Pb.08 is too big, the feedback energy of motor will be too large and may cause
over-voltage fault. If Pb.08 is too small, the feedback energy of motor will be too small to
achieve voltage compensation effect. So please set Pb.08 according to load inertia and
the actual load.
