PROBLEM TO BE SOLVED: To improve unstable operation of an electric motor caused by state changes of a servo amplifier. SOLUTION: The numerical controller 10 which drives the electric motor through the serve amplifier 5 is equipped with a means 1 which inputs state information on the servo amplifier fed back from the servo amplifier 5 and changes parameters of the numerical controller according to the state information, and this parameter changing means 11 changes the parameters of the numerical controller to control the electric motor in response to changes of the servo amplifier, thereby improving unstable operation of the electric motor caused by the state changes of the servo amplifier. |
