Description
T
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%
P03.24 sets the maximum output voltage of the
VFD, which is the percentage of rated motor
voltage. Set the value according to onsite
conditions.
Setting range:0.0–120.0%
Carry out motor pre-exciting during starting to build
a magnetic field inside the motor to improve the
torque characteristics of motor during starting.
