PROBLEM TO BE SOLVED: To provide a feed control method capable of confining motion errors within a tolerance level and preventing the generation of a lost motion. SOLUTION: A feed control device is provided with an analyzer 20 for analyzing a control program 10 for an object to be controlled, an interpolator 30, 31, 33 generating information indicating the state of the operation and a position command based on the analytic result, a position control unit 40 generating a torque command to drive the object to be controlled based on the position command generated by the an interpolation part, an arithmetic processor 51 that generates and feeds back the limiting value of the speed and acceleration within the range that inversion torque and the lost motion do not occur and to the interpolators according to the information indicating the torque command and the state of the operation.
