boost
Torque boost is used for the compensation of low
frequency torque. P04.01 is relative to the max.

.
P04.02 defines the percentage of closing
frequency of manual torque to f
b
.
Torque boost should be selected according to the
load. The bigger the load is, the bigger the torque
is. Too big torque boost is inappropriate because
the motor will run with over magnetic, and the
current of the VFD will increase to add the
temperature of the VFD and decrease the
efficiency.
When the torque boost is set to 0.0%, the VFD is
automatic torque boost.
Torque boost threshold: below this frequency
point, the torque boost is effective, but over this
frequency point, the torque boost is invalid.
