ABB PFEA113-20 3BSE050092R0 Tension Electronic Equipment

Product core positioning and application scenarios

As the "tension center" in the winding system, the core value of PFEA113-20 lies in converting tension sensor signals into precise control instructions, achieving closed-loop control of coil tension, and solving problems such as coil wrinkling, fracture, and stretching deformation caused by tension fluctuations in production. Its typical application scenarios cover key production processes in multiple fields:

-Paper industry: In the web, pressing, drying, and coiling stages of paper machines, precise control of paper web tension is achieved to avoid damage or creases, ensure uniform paper thickness and smooth surface, and improve the quality of finished paper.

-Textile and Printing and Dyeing Industry: Used in chemical fiber spinning, fabric printing and dyeing, and finishing processes to control the tension stability of yarns and fabrics, prevent yarn breakage and fabric stretching deformation, and ensure that the density and elasticity of textile products meet standards.

-Printing and packaging industry: In the unwinding, printing, and winding processes of printing substrates such as film and paper, maintain constant tension to avoid substrate deviation, inaccurate overprinting, or uneven winding, and improve printing accuracy and packaging aesthetics.

-Metal processing industry: For the rolling, slitting, and laminating processes of metal coils such as aluminum foil, copper strip, and steel strip, precise tension control is implemented to prevent cracking and deformation of the metal coils, ensuring the dimensional accuracy of subsequent processing.

Core functional features

1. High precision tension detection and control

The device supports multiple types of tension sensor signal inputs (such as strain gauges, piezoelectric sensors, etc.), with a signal acquisition accuracy of up to 0.1%, and can capture small tension fluctuations in real time. By using the built-in PID adjustment algorithm, the control signal is quickly output to the actuator (such as magnetic powder brake, servo motor) to control the tension deviation within a very small range, ensuring stable tension of the coil.

2. Flexible control mode adaptation

Provide multiple tension control modes that can be switched according to different production process requirements to meet the needs of complex winding scenarios. The main modes include: constant tension control (maintaining a constant tension value), taper tension control (decreasing tension according to a preset curve during the winding process to avoid deformation of the inner coil under pressure), and follow-up tension control (automatically matching tension with the host machine speed, suitable for linked production lines).

3. Powerful signal processing and adaptation capabilities

It has rich input and output interfaces and is compatible with tension sensors, encoders, and actuators of different specifications. Supports analog (4-20mA, 0-10V) and digital (RS485, PROFIBUS, etc.) signal transmission, and can seamlessly integrate with control systems such as PLC and DCS to achieve centralized monitoring and collaborative control of the production process.

4. Comprehensive protection and diagnostic functions

Built in various fault detection mechanisms such as over tension, under tension, sensor failure, and communication interruption. When abnormal situations occur, an alarm signal (sound and light alarm or software alarm) is immediately triggered, and the actuator can be linked for emergency handling (such as shutdown and deceleration) to avoid the expansion of production accidents. At the same time, the device supports fault recording and query functions, making it easy for operation and maintenance personnel to trace the cause of faults.

5. Convenient parameter setting and operation

Equipped with an intuitive operation panel (including buttons and display screen), users can directly set tension target values, control parameters, alarm thresholds, etc. on the device; Remote parameter configuration and monitoring can also be carried out through the upper computer software, with flexible and convenient operation. The device supports parameter saving and recovery functions, and can quickly import configurations when replacing the device, improving operation and maintenance efficiency.

Installation and usage precautions

1. Installation environment requirements: It should be installed in a ventilated, dry, dust-free, non corrosive gas and strong electromagnetic interference control cabinet, avoiding proximity to high-power frequency converters, contactors and other interference sources, and maintaining a distance of at least 10cm from heat sources (such as heaters).

2. Key points of wiring specifications: The tension sensor cable should use twisted pair shielded wire, with the shielding layer grounded at one end to avoid parallel laying with the power cable and reduce signal interference; Power supply lines need to be equipped with fuses (recommended 2A) to prevent overcurrent damage to equipment; Before wiring, be sure to disconnect the power supply and confirm that the pin definition matches the sensor and actuator.

3. Parameter configuration principle: Based on the material of the coil (such as paper, metal, film), thickness, width, and production speed, set the tension target value, PID parameters, and alarm threshold reasonably; During the first debugging, the "low tension testing machine" mode should be used to gradually optimize parameters and avoid damage to the coil due to improper parameters.

4. Daily maintenance focus: Regularly clean equipment panels and wiring terminals, check if cable connections are secure; Check the installation status of the tension sensor every week (such as whether it is loose and whether the force is evenly distributed); Backup device parameters every month, regularly check fault records, and promptly address potential issues.

5. Calibration requirements: It is recommended to perform tension calibration on the equipment every 6 months using standard weights or specialized calibration instruments to ensure that the tension detection accuracy meets production requirements; After replacing the tension sensor or repairing the equipment, it must be recalibrated.
