AXIS#.FIELDWEAKENING.CURRFILTERBW
Description
This keyword determines the bandwidth of the second order low-pass biquad filters that are applied on the q-axis and d-axis currents for noise reduction. These currents are used inside the field weakening algorithm for regulating the motor-voltage-vector-magnitude when operating above base speed. Lower bandwidths result in cleaner signals but can also create phase lag and lower the phase margin of the system. Depending on the required speed of the motion, they can be adjusted.
