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 inverter will increase to
add the temperature of the inverter and
decrease the efficiency.
When the torque boost is set to 0.0%, the
inverter 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
