P 4.4.4.9 Low Speed Filter Time Const.
This time constant is used above 10% rated speed. Obtain quick control through a short damping time constant. However, if this value is
too short, the control gets unstable.

P 4.4.4.10 Voltage Filter Time Const.
Use this parameter to reduce the influence of high frequency ripple and system resonance in the calculation of supply voltage. Without
this filter, the ripples in the currents can distort the calculated voltage and affect the stability of the system.

P 4.4.4.11 Variable Torque Zero Speed Magnetization
Use this parameter along with P 4.4.4.12 Min Speed Normal Magnetizing [Hz] to obtain a different magnetizing current on the motor
when running at low speed. Enter a percentage value of the rated magnetizing current. If the setting is too low, the torque on the motor
shaft may be reduced.
