Claim 0:
1. A system comprising:
a moving part that is driven by a servo motor;
a numerical control device that generates a movement command for the moving part;
a filter that shapes the movement command generated by the numerical control device and limits frequencies to be passed;
a detector that detects a position or a speed of the moving part;
a servo amplifier that controls a force generated by the servo motor or a force transmitted to the moving part such that a deviation between an output from the filter and a detection value detected by the detector becomes 0, wherein a vibration of the moving part is controlled by a change of an amplification factor used for amplifying the deviation in the servo amplifier, a measurement, from the deviation, of a frequency and an amplitude of vibration superimposed on the moving part, and a change of the filter based on the frequency and the amplitude.
