Min. flux-weakening limit of motor
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
curvature by modifying the flux-weakening
control coefficient. The larger the coefficient, the
steeper the curve, the smaller the coefficient, the
smoother the curve.
P03.22 is valid only for vector mode 1.
Setting range of P03.22: 0.1–2.0

Pre-exciting
time
Pre-exciting is performed for the motor when the
VFD starts up. A magnetic field is built up inside
the motor to improve the torque performance
during the start process.
Setting range: 0.000–10.000s
