Investigating an issue where two axes sit on the same seals. Excitation of one axis (Z-axis), displaces the other (Y-Axis) and vice versa. I have made attempts to tune the opposing with Integrator (with Integration mode = 1)...results got worse. Deadband Gain, had marginal improvements, but could be improved. My next approach is to use a notch filter in an attempt to use this as a low pass filter. For the cut-off frequency, being a component of the Velocity....with this FFT how would I determine the appropriate value, or by what process? Thank You Y-Axis Velocity FFT.bmp
