A numerical controller that can easily set parameter values related to servo control used within itself. Machine constants are set in the numerical controller. The numerical controller calculates the parameter values related to the servo control used in the numerical controller, from the set machine constants, and stores and sets them in a memory means within the numerical controller. The parameter values calculated are also fed to an output device such as a display device for an operator to check them. When a machine to be controlled by the numerical controller is determined, the machine constants can be easily obtained from the specifications or the like of the machine and set in the numerical controller. Since the numerical controller itself calculates and sets the parameter values related to the servo control, the setting can be easily carried out without full knowledge of the internal elements, structure and operation principle of the machine, the processing performed by the numeric control unit, etc.
