Core functional features
1. High precision tension closed-loop control
The controller adopts advanced PID closed-loop control algorithm, combined with high-resolution tension signal acquisition module, which can capture small changes in material tension in real time and quickly adjust the output signal to stabilize the tension value within the set range. Even in dynamic scenarios such as material speed changes and load fluctuations, the control accuracy of ± 0.1% FS can still be maintained, effectively avoiding problems such as material tensile deformation, wrinkling, and fracture.
2. Flexible parameter configuration and scene adaptation
Supports multiple tension control modes, including constant tension control, taper tension control (applicable to winding processes), tension following control, etc., which can be switched according to different production process requirements. Key parameters such as tension target value, PID parameters, alarm threshold, etc. can be easily set through panel buttons. It also supports parameter saving and calling functions, and can quickly switch configurations for different product production formulas.
3. Comprehensive alarm and protection mechanisms
Built in multiple alarm functions such as over tension, under tension, sensor failure, and power supply abnormality. When the device detects abnormal conditions, it will immediately display alarm information on the display screen and output alarm signals (which can be linked to shutdown or sound and light alarm devices), reminding operators to handle the situation in a timely manner and avoiding the expansion of the fault. At the same time, the controller itself has overcurrent and overvoltage protection functions, which enhance the safety and service life of equipment operation.
4. Strong anti-interference and stable operation performance
Adopting industrial grade circuit design and passing EMC electromagnetic compatibility certification, it has strong anti-interference ability and can effectively resist interference factors such as electromagnetic radiation and voltage fluctuations in industrial sites, ensuring the stability of signal transmission and control output. The wide voltage input design further enhances the adaptability of the equipment in different power grid environments and reduces operational failures caused by power supply issues.
5. Convenient communication and integration capabilities
Equipped with RS485 communication interface and supporting standard Modbus RTU protocol, it can easily connect to industrial control systems such as PLC and SCADA, realizing remote setting of tension parameters, real-time data acquisition, and equipment operation status monitoring. Facilitating the construction of a centralized production management system, improving the automation level and management efficiency of the production process.
Typical application scenarios
-Metallurgical industry: used for rolling, straightening, and coiling processes of metal coils such as steel strips and aluminum strips, controlling the tension of metal strips, ensuring uniform thickness and smooth surface, and reducing the risk of strip breakage during the rolling process.
-Paper industry: In processes such as paper copying, rewinding, and slitting, maintaining stable paper tension, avoiding wrinkles, damage, or uneven elasticity, and ensuring paper quality and subsequent processing accuracy.
-Textile industry: suitable for the stretching and winding processes of textile materials such as synthetic fibers and yarns, accurately controlling material tension, ensuring yarn uniformity, and improving the quality of textiles.
-Film/Packaging Industry: Used for extrusion, printing, and slitting processes of plastic films and composite films, controlling film tension, preventing film stretching deformation or bubble formation, and ensuring the dimensional accuracy and printing quality of films.
-Cable industry: During the drawing, twisting, and extrusion processes of cables and wires, the tension of cable conductors or insulation layers is controlled to ensure the stability of cable structures and improve product performance.
Installation and usage precautions
1. The equipment should be installed in a well ventilated, dry, dust-free, and non corrosive gas control cabinet, avoiding direct sunlight and severe vibration. The installation environment temperature should be controlled within the range of -10 ℃ to 55 ℃.
2. Before wiring, it is necessary to confirm that the power supply matches the rated voltage of the controller, strictly follow the product wiring diagram for wiring, distinguish the input, control output, communication interface and other circuits of the tension sensor, and avoid equipment damage caused by misconnection.
3. The tension sensor should be installed in a position where the force is evenly distributed and mechanical impact is avoided, ensuring that the signal cable between the sensor and the controller is well shielded to reduce the influence of interference signals.
4. Before the first use, parameter initialization settings should be carried out, and the tension sensor should be calibrated according to the actual load and process requirements. PID parameters should be configured reasonably to ensure that the controller achieves the best control effect.
5. In daily use, the equipment panel should be cleaned regularly, and the wiring terminals should be checked for looseness to avoid faults caused by poor contact; Regularly backup device parameters for easy fault recovery.
