Abstract: A numerical controller includes a commanded movement-amount adjustment section, in addition to a position command section and a positional deviation counter but also. The commanded movement-amount adjustment section calculates an adjusted command movement amount based on a commanded movement amount output from the position command section, positional deviation acquired from the positional deviation counter, and an actual velocity of a control axis, and outputs the calculated adjusted command movement amount to the positional deviation counter. When a load acts on a servo motor so that positional deviation is accumulated and the load is abruptly removed, a situation in which the servo motor abruptly accelerates with its maximum torque in an attempt to eliminate the accumulated positional deviation is avoided.
