Use the functions given in this chapter, if you are not satisfied with the machine status after making
adjustment in the methods in section 4.6.
5.1 Filter functions
The servo amplifier MR-J2-Super have different filter functions:
Machine resonance suppression filter
Low-pass filter
If a mechanical system has a natural resonance point, increasing the servo system response
level may cause the mechanical system to produce resonance (vibration or unusual noise) at
that resonance frequency. As a result vibrations or higher levels of noise arise. The filter
functions serve to suppress any such resonance that may appear.
