5: Customized V/F (V/F separation); in this
mode, V can be separated from f and f can be
adjusted through the frequency given channel
set by P00.06 or the voltage given channel set by
P04.27 to change the feature of the curve.
Note:

P04.01 Torque boost Torque boost to the output voltage for the
features of low frequency torque. P04.01 is for
the max. output voltage V
b
.
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 valid, but over this
frequency point, the torque boost is invalid.
