Abstract
Improved precision is realized in positioning control. Provided is a servo control device that is applied to a numerical control equipment provided with a screw-feeding section that converts rotational movement of a motor to linear movement, a driven section that is linearly moved by the screw-feeding section, and a support member by which the screw-feeding section and the driven section are supported and that controls the motor so as to match a position of the driven section to a positioning instruction, including a support-member-reaction-force compensating sectionthat compensates for vibrations of the driven section due to a vibrational reaction force of the support member, wherein a transfer function provided in the support-member-reaction-force compensating sectionincludes a stiffness term for the driven section.
