Weakening
coefficient
in constant
power zone
The usage of motor in weakening control.
Function code P03.22 and P03.23 are effective
at constant power. The motor will enter into the
weakening state when the motor runs at rated
speed. Change the weakening curve by
modifying the weakening control coefficient.
The bigger the weakening control coefficient is,
the steeper the weak curve is.
Setting range of P03.22: 0.1
