What Are The Advantages Of Tension Control Variable Frequency Winding?

  In many industries where industrial production is carried out, precise tension control is required to maintain a constant tension to improve the quality of the product. Industries such as paper, printing and dyeing, packaging, wire and cable, fiber optic cable, textiles, leather, foil processing, fiber, rubber, metallurgy, etc. are widely used.

          Before the frequency conversion technology is still mature, DC control is usually used to obtain good control performance. With the maturity of frequency conversion technology, some high-performance inverters such as vector control inverters and tension control special inverters have emerged. Its control performance is comparable to DC control performance. Because of the structure, cost performance, use, maintenance and other aspects of the AC motor, it is superior to the DC motor.
         The purpose of tension control is to keep the tension on the wire or strip constant. Let's take a look at the advantages of tension control inverter winding.
1. The tension setting is set on the man-machine, the humanized operation, the unit is the unit of force: Newton.
2. Use advanced control algorithms: recursive operation of the winding diameter; linear addition of tension when the hollow winding diameter is activated.
3. The application of the calculation formula of the tension taper, the dynamic adjustment of the torque compensation, etc.

4, the real-time calculation of the winding diameter, the accuracy is very high, to ensure the smooth performance of the winding motor output torque. And the recursive operation of the roll diameter is added when calculating the roll diameter, and when the operation is wrong, the roll diameter can be corrected to the correct value by itself.
5. The tension control is transformed into the frequency conversion winding on the basis of the traditional mechanical transmission winding, which is very simple and low in cost, and basically does not need to modify the original machinery. The transformation period is small, and it can be installed and debugged basically in two or three days.
6. Overcoming the drawbacks of mechanical winding on mechanical wear and prolonging the service life of the machine. Convenient maintenance of equipment.
