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 coefficienct. The bigger the
weakening control coefficienct is, the steeper the
weak curve is.
