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

P03.24
Max. voltage limit
P03.24 sets the max. output voltage of the inverter,
which is the percentage of rated motor voltage. This
value should be set according to field conditions.
Setting range:0.0–120.0%

P03.25
Pre-exciting time
Carry out motor pre-exciting during starting to build a
magnetic field inside the motor to improve the torque
characteristics of motor during starting.
