Abstract
A servo control device includes a coarse-movement reference model unit calculating a coarse-movement model position by performing predetermined filter computation based on a position command; a coarse-movement follow-up control unit controlling the coarse-movement shaft motor such that a coarse-movement-shaft motor position follows the coarse-movement model position based on the coarse-movement-shaft motor position provided from the coarse-movement shaft motor and the coarse-movement model position; an integrated reference model unit calculating an integrated model position by performing predetermined filter computation based on a position command; and a fine-movement follow-up control unit controlling the fine-movement shaft motor such that a fine-movement-shaft motor position follows a fine-movement model position based on the fine-movement-shaft motor position provided from the fine-movement shaft motor and the fine-movement model position obtained from the integrated model position and the coarse-movement model position.
