In the strip production enterprises of reeling lines, such as steel, aluminum-platinum, web, etc., the cutting system, many enterprises basically still use the closed-loop control system composed of the previous DC or AC frequency conversion, the cutting Although the accuracy can meet the basic requirements, it is often not very high. With the development of society, the production enterprises strive for perfection, which is also important for improving their brand image. At the same time, it also meets the increasingly high requirements of customers.
System principle
Figure 4: Program diagram.
Advantages of using AC servo
â– Smooth operation, no vibration at low speed;
â– The control precision is high, and the control precision of the AC servo is guaranteed by the rotary encoder at the rear end of the motor shaft;
â– Fast response time, acceleration and deceleration time can be completed in a very short time;
â– Constant torque output, independent of speed;
â– Has strong overload capability;
â– The AC servo drive system itself forms a closed loop and the control is more reliable.
Conclusion
After adopting this system, our system has greatly improved stability and precision, reduced losses, met the higher requirements of customers, and achieved significant economic benefits. At the same time, we have accumulated experience for future promotion. In the next few years, our company has changed other pipelines one after another, and the lower cost has achieved good results. Later, it was recognized and promoted in the same industry. Later, all the lines were used in this similar system, and the original frequency conversion method was abandoned.
