The servo adjuster (6) stores a plurality of command response indicators (61) and a plurality of stiffness indicators (62). The servo adjuster (6) also generates an evaluation indicator measuring pattern (63) by a combination of each command response indicator (61) and each stiffness indicator (62). A motor (3) is driven in accordance with the generated evaluation indicator measuring pattern (63) while the command response indicators (61) and the stiffness indicators (62) are sequentially changed.
