Torque boost

【 20.0 ％】
Torque boost will take effect when output
frequency is less than cut-off frequency of torque
boost ( F 4.0 2 ). Torque boost can improve the
torque performance of V/F control at low speed.
The value of torque boost should be determined
by the load. The heavier the load, the larger the
value is . I f the boost is too large, the motor will run
in exciting. T he efficiency of the motor decreases
as the current of the inverter increases and the
motor increase the heat-releasing.
W hen the torque boost is set to 0.0% , the inverter
is in the automatic torque boost state.
Cut-off point of torque boost ： the torque boost
is valid under this point, and the torque boost is
invalid when exceeding this set frequency.
