Weakening
coefficient
in constant
power zone
Used when the AM is in flux-weakening
control.
The function codes
P03.22
and
P03.23
are
valid at constant power. The motor enters
the flux-weakening state when the motor
runs above the rated speed. Change the
flux-weakening curve by modifying the
flux-weakening control coefficient. The larger
the coefficient, the steeper the curve, the
smaller the coefficient, the smoother the
curve.
