low-frequency torque characteristics of V/F.
You should select torque boost based on the load,
for example, larger load requires larger torque
boost, however, if the torque boost is too large, the
motor will run at over-excitation, which will cause
increased output current and motor heat-up, thus
degrading the efficiency.
When torque boost is set to 0.0%, the VFD is
automatic torque boost.
Torque boost cut-off threshold: Below this
frequency threshold, the torque boost is valid,
exceeding this threshold will nullify torque boost.

V/F frequency
point 1 of motor 1
When P04.00 =1 (multi-point V/F curve), you can
set V/F curve via P04.03
–P04.08.
V/F curve is usually set according to the
characteristics of motor load.
Note:
V1<V2<V3, f1<f2<f3. If low-frequency
voltage is set too high, motor overheat or
burnt-down may occur, and overcurrent stall or
overcurrent protection may occur to the VFD.
