Numerical controlling unit |
摘要 |
The invention relates to a numerical controlling unit 10 having a speed-feedback controlling system. A peak-frequency detector 20 determines a peak frequency from a characteristic of a frequency transfer function whose input is a speed-instruction input signal and whose output is a speed feedback signal. A band elimination component 30 conducts a band elimination process to the speed-instruction input signal, based on the peak frequency.
