The value of PB.05 determines the pre-warning category, such as motor overload (OL1)
or inverter overload (OL2).
PB.04 determines the current threshold of pre-warning actionn, it is a percentage of the
rated current. When output current of inverter exceeds the value of PB.04 and last the
duration determined by PB.06, inverter will output a pre-warning signal. Please refer to
following diagram:

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
