An error display device is a device for displaying a translation error and an attitude error associated with a rectilinear motion of a machine element, and includes a reference-motion-trajectory display unit that displays a design motion trajectory, and an error magnification/display unit that magnifies the translation error and the attitude error and displays the magnified errors, wherein the error magnification/display unit calculates a translation error vector including a magnified translation error obtained by multiplying the translation error by a predetermined magnification factor, draws a translation error trajectory including the design motion trajectory and the translation error vector added thereto, calculates an attitude error matrix including a magnified attitude error obtained by multiplying the attitude error by a predetermined magnification factor, and draws a predetermined shape with coordinates transformed using the attitude error matrix and the translation error vector. |
