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.
