Introduction
ContentVariable frequency control cabinet
When designing Qingyun wire drawing machines, product designers found that the industry has always followed the principle of equal flow rate per second per unit time in terms of control methods. Using this principle, calculate a relatively accurate speed, and then combine it with the tension arm position signal to perform fine tuning through PID. This control method has the following drawbacks:
1. Without touch screens or text displays, the cost is relatively high;
2. Not convenient to use: Once the aperture of the mold is changed, parameters need to be reset; After jumping the coil, it is necessary to reset the mold aperture and mechanical transmission ratio.
Advantages of special frequency converters for wire drawing machines:
1. Robust winding function winding model, achieving automatic recognition and setting of winding diameter;
2. Automatic tracking of host speed;
3. Smooth start, smooth operation, and constant tension;
4. The use of feedforward PID control scheme can completely replace external PID.
Application scenarios:
Industries that require tension control, such as wire and cable industries, winding industries, and metal wire drawing industries
