PROBLEM TO BE SOLVED: To improve the control precision of a driving and controlling device for a winding machine by providing a changing circuit which selects the tension distribution value distributed with a tension distributor or the total tension standard value, and outputs it to a tension standard circuit. SOLUTION: A tension distributor 10 distributes the total tension standard value outputted from a total tension standard circuit 11 corresponding to the motor capacity of AC motors 4a, 4b. A changing circuit 13 selects the tension distribution value distributed with the tension distributor 10 or the total tension standard value and outputs it to tension standard circuits 9a, 9b. When the tension is high, two stands of AC motors are driven and used, when the tension is low, only AC motor 4a side is applied with the tension standard from the total tension standard circuit 11, and AC motor 4b, is not applied with tension, then only compensation at the time of accelerating, decelerating and the compensation of mechanical loss are executed. |
