Min. flux-weakening limit of motor
P03.22 and P03.23 are valid during constant
power. When motor speed is above rated speed,
motor enters flux-weakening running state. The
flux-weakening control coefficient can change
the flux-weakening curvature, the larger the
coefficient, the steeper the curve, the smaller the
coefficient, the smoother the curve.
Setting range of P03.22: 0.1–2.0
Setting range of P03.23: 10%–100%
