7: Ethernet communication
8: Pulse frequency HDIB (100% corresponding
to triple the motor rated current)
9: EtherCAT/Profinet communication
10: Programmable expansion card
11: 216 communication

1–11: Same as those for P03.18
0.0–300.0% (of the motor rated current)
Note: It can be modified only when P11.26=1
indicating special functions are enabled.
Used when the AM is in flux-weakening control.
T
Min. flux-weakening limit of motor
The function codes P03.22
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
