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.
T
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
