P04.02
Torque boost
close
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.

When P04.00 =1, the user can set V//F curve through
P04.03–P04.08.
V/F is generally set according to the load of the motor.
Note:V1＜V2＜V3, f1＜f2＜f3. Too high low frequency
voltage will heat the motor excessively or damage.
Overcurrent stall or overcurrent protection may occur.
Setting range of P04.03: 0.00Hz–P04.05
