P03.22
Weakening
coefficient
in constant
power
zone
The usage of AM 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.
The setting range of P03.22: 0.10~2.00
The setting range of P03.23: 5%~50%
