INVT TM751 PLC for High-Speed Cable Rewinding in Cable Manufacturing

In recent years, China has vigorously promoted the intelligent transformation of the manufacturing industry, and the requirements for wire quality in industries such as electronics manufacturing, aerospace, and metal processing have been continuously increasing. As a key piece of equipment in the wire winding process, high-speed rewinding machines are rapidly developing towards high precision, high speed, and intelligence.

Customer requirements

Traditional rewinding machines are unable to meet market demands in terms of tension control, wire breakage detection, and automation. When upgrading its production line, a cable manufacturer proposed a more stable and intelligent drive solution to improve production efficiency and reduce losses.

1. High-precision tension control: The system is required to have excellent dynamic response characteristics to achieve precise and stable control of wire tension and ensure consistency in the winding process.

2. Ultra-high speed operation: The system needs to maintain stability under extremely high linear speed conditions, while achieving smooth start-stop transitions and eliminating abnormal conditions during operation.

3. Intelligent management: The system supports automatic anomaly detection and has remote monitoring capabilities, enabling traceable management of production data.

INVT Solution

To address customer needs, INVT offers a system solution consisting of VS series HMI+TM751 PLC controller+ High-performance DA200A series servo drive, achieving the following three major breakthroughs:

• Precise control: TM751 PLC controller features high-response logic control, supports multi-axis coordination, and dynamically matches the winding and unwinding speeds through roll diameter calculation and tension lever PID adjustment. The lever angle remains stable within the 0~0.5 degee range, significantly reducing the risk of wire breakage.

• Stable operation: DA200A servo system supports a linear speed of 800 m/min and automatically and smoothly stops the machine in the event of a power outage to avoid material waste.

• Intelligent detection and interconnection: Integrated with real-time monitoring of wire breakage and jamming, it works with the TM751 PLC for rapid shutdown response; it also supports remote monitoring, facilitating digital management.
