Abstract
A numerical controller for controlling a machine receives an instruction to reestablish a machine coordinate value of a movable part of the machine and stops a servo motor driving the movable part. When the servo motor is stopped, the numerical controller acquires position information of a position detector provided to the servo motor. Then, the numerical controller updates the machine coordinate value of the movable part based on the position information, and further updates the absolute coordinate value of the movable part based on the updated machine coordinate value.
