[Reference] Adjusting notch filter
l When setting the notch filters (NP and NS), you need to measure the resonant frequency by
checking voltage between the analog velocity monitor pins (VELOCITY-GND terminals) on the
front panel of Driver by means of an oscilloscope, etc.
à Check the resonant frequency as show in Figure5-3. If the frequency is 200 Hz, type as
