Torque boost to the output voltage for the features
of low frequency torque. P04.01 is for the Max.

P04.02 defines the percentage of closing frequency
of manual torque to f
b
.
Torque boost should be selected according to the
load. The bigger the load is, the bigger the boost is.
Too big torque boost is inappropriate because the
motor will run with over-magnetic, and the current
of the inverter will increase to raise the temperature
of the inverter and decrease the efficiency.
When the torque boost is set to 0.0%, the inverter
is automatic torque boost.
Torque boost threshold:under the threshold, the
torque boost is valid, but over the threshold, the
torque boost is invalid.
