P04.01
Torque boost of
motor 1
In order to compensate for low-frequency torque
characteristics, users can make some boost
compensation to the output voltage.
relative to the max. output voltage V
b.
defines the percentage of cut-off
frequency of manual torque boost to the rated
motor frequency f
b.
Torque boost can improve
the low-frequency torque characteristics of V/F.
Users should select torque boost based on the
load, eg, 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 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.
