Flux

coefficient in
constant power
zone
The usage of motor in flux weakening control.
Function code P03.22 and P03.23 are effective
at constant power. The motor will enter the flux
weakening state when running at rated speed.
Change the flux weakening curve by modifying
the flux weakening control coefficient. The bigger
the flux weakening control coefficient is, the
steeper the weakening curve is.
