Torque boost can improve the low frequency torque characteristics of VF, reduce the torque boost when the load
is light, and increase when the load is heavy and the starting torque is not enough. When the torque boost is too
large, the motor will be over excited, the output current of the inverter will increase, the motor heating will
increase, and the efficiency will decrease.

VF separation is generally used in induction heating, inverter power supply and torque motor control.
When VF separation control is selected, the output voltage can be set by parameter P5-10, or from analog
quantity, multi-section instruction, PLC, PID or communication. When non digital setting is used, 100% of each
setting corresponds to the rated voltage of the motor. When the percentage of analog output setting is negative,
the absolute value is taken as the effective setting value.
