摘要
A servo motor controller includes a speed command - generating means for generating a speed command value of the servo motor, a speed detection unit, which a speed of the servomotor is detected, a torque command - generating means for generating a torque command value, a sinusoidal waves - generating means for generating a sinusoidal interference shaft, a frequency response - calculating unit for calculating a frequency response, if the sinusoidal interference value in a speed loop has been entered as a rule, a resonance frequency - detection unit for detecting a resonant frequency, in which amplification is maximized, a resonance frequency - memory unit for storing the resonant frequency - detection unit, at least one filter for damping a specific frequency band component, which is contained in the torque command value, and a resonant frequency - comparison unit for measuring the rigidity of a machine tool on the basis of the resonant frequency and adjusting the filter in relation to the resonant frequency.
