Set torque boost
Motor torque can be adjusted to increase the output voltage when the starting torque
is not sufficient in V/F control. Pay attention not to cause the motor to burnout and
an inverter trip. Set boost value in 70 to 90 when using VP1, VP2 or VP3 in V/F control mode.
Setting is effective only when V/F control is selected.
