Figure 6.3 1 Motor overload protection curve.
The value can be determined by the following
formula:
Motor overload protection current = ( Maximum
load current / inverter rated current) * 100%

100% of F b.04 corresponds to the standard bus
voltage.
If F b.05 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 F b.04. The inverter can
continue to run without tripping by reducing its
output frequency and feedback energy via motor.
