11: V/f half separation mode. In this mode, V and F are proportional, but the proportional relationship can be set
by voltage source 03-13, and the relationship between V and F is also related to the rated voltage and rated
frequency of motor group 01.
Assuming that the voltage source input is X (X is a value of 0~100%), the relationship between the output voltage
V of the inverter and the frequency F is:V/f=2 * X * (motor rated voltage)/(motor rated frequency)

Torque boosting can improve the low-frequency torque characteristics of V/f and do boost compensation for the
output voltage. However, if the torque boost setting is too large, the motor is easily overheated and the inverter is
easily overcurrent.
When the torque boost is set to 0.0, the inverter is in automatic torque boost, and the inverter automatically
calculates the torque boost value according to the motor stator resistance and other parameters.
Torque boost torque cut-off frequency: Below this frequency, the torque boost is valid, and beyond this set
frequency, the torque boost is invalid, as shown in Figure 5-3.
