Minimum flux-weakening limit
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.
Setting range of P03.22: 0.1–2.0
Setting range of P03.23: 10%–100%
