When fault restart function is valid, motor may start suddenly, so
when this function is used, please pay attention to safety.

Settings
0: Inverter start detecting over torque only in
constant speed, inverter continues operation
during over torque
1: Inverter start detecting over torque only in
constant speed, inverter stop during over torque
2: Inverter always detecting over torque, inverter
continues operation during over torque
3: Inverter always detecting over torque, inverter
stop during over torque

When output current of inverter exceeds setting value of P423, inverter
start calculate the over torque time. When the duration exceeds half
of setting value of P424, inverter output pre-alarm signal. Inverter
continues output until the over torque time exceeds P424 setting, and
then inverter protects and output alarm signal.
If P423=0. over torque detection is invalid, and 100% is inverter
rated current.
