The servo driver has five sets of notch filters, each with three parameters, notch frequency, notch attenuation and
notch bandwidth. The first and second notches are set automatically, and the third, fourth and fifth are set
manually.
The torque instruction filter and notch filter are in series in the system. As shown in the figure below, the switch
of the notch filter is controlled by P2-69 and P2-70.
