This function defines the cut-off frequency of torque boost, as shown in Fig. 4-3 as Fz. Then cut-off frequency is suitable for
any V/F curve defined by P0.02.

Torque boost voltage will change with the motor stator’s current changes. The bigger the stator is, the higher the boost
voltage.
Carrier frequency will effects the motor’s noise and heat waste.The relationship among carier frequency, motor noise, leak
current, and dist are shown below:
