In the case of dual-feedback control that refers to an external encoder, the filter time constant
is set to 0.1 ms at the time when the mode switches between semi-closed control and full-
closed control.
As the setting value gets close to 0 ms, it refers to the external encoder more. As it gets close
to 100 ms, it refers to the motor-side encoder more. It minimizes the vibrations that are
generated due to mechanical characteristics or external factors to shorten the adjustment
time.
