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.

Max. voltage limit
P03.24 sets the max. output voltage of the
VFD, which is the percentage of motor rated
voltage. Set the value according to onsite
conditions.

P03.25
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.
