PURPOSE:To save the consumption power of a servo-controller, by using the counter-electromotive force of a motor, and by controlling current according to each control mode. CONSTITUTION:By a discriminating means 13, a counter-electro-motive force generated by the rotation of a servo-motor 18 is compared with input signal, and a control mode controlling the current of the servo-motor 18 is discriminated, and to a control means 14, control mode command and control signal are transmitted. By the control means 14, based on the mode command, current control storing a counter-electromotive force in a condenser, current control using the stored electric charge for a forward electromotive force, and current control using the counter-electromotive force for braking are separately executed, and as a result, the counter-electro-motive force is effectively used, and the consumption of the power of a servo-controller is reduced. |
