PFXA 401 Tension control detects tension in real-time through a tension sensor and performs PID calculation of tension through a tension controller or PLC. The essence of this tension control is to achieve dynamic constant tension by adjusting the speed difference.
PFXA 401 Application Fields
The multi-level synchronization and tension control system is widely used in industries such as textile, printing and dyeing, and papermaking (dyeing and pulp combined machines, printing and dyeing equipment).

PFXA 401 Analysis of Disadvantages and Shortcomings
Firstly, it can be seen that the synchronization of the system belongs to open-loop control. When the load changes significantly, the slip rate of the motor will increase, and the corresponding tension roller will deviate from the balance position. The speed of the corresponding motor may change, and there may be certain limitations in situations where synchronization requirements are very strict. Meanwhile, due to the fact that both speed setting and feedback are analog signals, and unpredictable factors such as long production lines and equipment installation, it may be more susceptible to various electrical coupling interferences, resulting in unstable system operation.
The tension control adopts PID, and due to the effect of integration, if the integration gain is not adjusted well, it is easy to cause system oscillation or response lag. The requirements for various parameters of PID operation are high. But in situations where the requirements are not very high, the system is still relatively stable and has a wide range of applications.
