PURPOSE: A servo control is provided to correct an elastic dislocation error in hybrid control type, suppress a synchronous error in interpolation on multiple axes, and improve a contouring motion precision. CONSTITUTION: A reference numeral(12) denotes a mechanical system including such a load as feed a screw, a table. A reference numeral(13) denotes low-pass filter. A reference numeral(15) denotes a velocity feedforward part. A reference numeral(16) denotes an acceleration feedforward part. A reference numeral(17) denotes an operating part for calculating a corrected value K of the gain ratios between axes. A reference numeral(18) denotes a feedforward correcting part.
