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.
