A copper wire factory in Shenzhen, Guangdong Province uses a dual-inverter-controlled intermediate wire drawing machine. The main drive motor adopts a 37-KW inverter and the winding motor adopts a 5.5-KW inverter. The intermediate wire drawing machine is equipped with annealing mechanism, but it does not have a tension frame. Therefore, a CHV general inverter equipped with a tension control card is adopted for winding. With the tension setting and winding diameter calculating functional module, the machine can implement wire winding at a constant tension. It does not have tension feedback torque control mode. The schematic diagram of tension control is shown as follows:
