    Abstract: A preload torque value generating unit (22m) generates a preload torque value (Tpm) as a function of the acceleration (am) of a main motor (6m), the preload torque value (Tpm) being a torque value that is appended in advance to a torque command value (Tm) so that the direction of force applied to the main motor (6m) and the direction of force applied to a sub motor (6s) will become opposite to each other. A preload torque value generating unit (22s) generates a preload torque value (Tps) as a function of the acceleration (as) of the sub motor (6s), the preload torque value (Tps) being a torque value that is appended in advance to a torque command value (Ts) so that the direction of force applied to the main motor (6m) and the direction of force applied to the sub motor (6s) will become opposite to each other.
