Weakening
P03.22 coefficient in
constant power field
Lowest weakening
P03.23 point in constant
power field
P03.22 is only valid to the vector mode 1 and close loop vector.
The motor is used in weakening control.
P03.22 and P03.23 are valid at constant power. When the motor runs above the rated rotating speed, it
comes into weakening state. The curvature of weakening curve can be changed by modifying the control
coefficient. The larger the coefficient is, the steeper the curve is.

proportional gain
P03.24 sets the maximum voltage the inverter can output, which is decided by practical situations.
P03.25: the inverter carries out motor pre-exciting at starting and sets up magnetic field inside the motor
to improve the torque performance during starting.
P03.26: The parameters are valid in weak magnetic control. The running performance of the motor can
be improved by adjusting the parameters properly.
P03.24~P03.26 are invalid to vector control mode 1 and V/F control.
