Abstract
An objective of the present invention is to reduce the downtime which occurs when changing a servo motor device. A servo motor device includes a motor section and a reduction gear configured to output a driving force by reducing a speed of rotation of the motor section, wherein a control device includes a detecting section configured to acquire detected information about operation of the motor section, and a computing section configured to generate an approximate curve based on a behavior for a time sequence of a parameter and to calculate predicted lifetime information of the servo motor device based on the approximate curve thus generated, wherein the parameter has been calculated by means of the detected information.
