The function codes are used to set torque
limits.
Setting range: 0.0–300.0% (of the motor rated
current)

Used when the AM is in flux-weakening
control.

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.
Setting range of P03.22: 0.1–2.0
