makeup for the output voltage of the VFD when it is in low frequency.
If the settings for torque boost is too high, the electric motor will become too hot
and the VFD will be in over-current. Generally, when setting the torque boost, do
not exceed 8.0%.
Adjust this parameter effectively can avoid over-current when start up. As for large
load, it is recommended to increase this parameter, and reduce this when the load
is light.
When torque is increased to 0.0, the VFD will in the status of automatic torque boost,
the VFD will automatically calculate the needed torque boost value according to the
parameters of stator resistance etc.
Torque boost and torque cutoff frequency:under this frequency, the torque of torque
boost is effective, but if exceed this set frequency, the torque boost will be invalid.
