Mtr Current Lim
Sets the largest allowable motor stator current. The online maximum value of this
parameter is Par 2 [Motor NP FLA]. The online minimum value is 105% of the current
indicated in Par 488 [Flux Current].

Motor Flux Est
Q-axis motor voltage is divided by the motor frequency while field weakening is active.
This is used to convert the torque command to a motor current (Iqs) command.

reference above base speed.

Flx LpassFilt BW
Sets the bandwidth of the filter that adjusts the response of the flux estimate used in the
torque to current conversion. Since the field time constant varies between motors, a
better control response may be obtained by adjusting the filter time constant. Normally
this parameter is not changed unless a significant disturbance occurs as the motor enters
field weakening AND Par 360 [Min Flux] is less than 1 per unit.
