The value of P9.05 determines the pre-warning category, such as motor overload (OL1)
or inverter overload (OL2).
P9.04 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 P9.04 and last the
duration determined by Pb.06, inverter will output a pre-warning signal. Please refer to
