constant power
zone
Used when the motor is in weakening control.
The function codes P03.22 and P03.23 are valid
at constant power. The motor will enter the
weakening state when the motor runs at the
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.
