ABB TB820V2

ABB TB820V2 Product Introduction
**1. Product Overview**  
**Model**: TB820V2  
**Series**: ABB **Tension Control** Series  
**Type**: **Tension Controller**  
**Applications**: Industrial processes requiring precise tension control, such as web processing, printing, packaging, film stretching, and wire/cable production.  
**2. Key Features**  
**High-Precision Tension Control**  
- Utilizes **closed-loop control algorithms**, supporting both **direct tension control** and **indirect tension control** (via speed/torque adjustment).  
- Control accuracy up to **±0.5%**, ideal for high-speed, high-precision production.  
**Multiple Operation Modes**  
- **Speed Mode**: For constant-speed unwinding/rewinding.  
- **Torque Mode**: Directly controls material tension.  
- **PID Adjustment**: Automatically compensates for tension fluctuations (e.g., material thickness variations).  
**Compatibility with Various Sensors**  
- Supports **analog signals (0-10V / 4-20mA)**, **digital encoders**, or **direct tension sensors** (e.g., Load Cell).  
**Integrated Automation Interfaces**  
- **Fieldbus Communication**: PROFIBUS DP, Ethernet/IP, Modbus RTU/TCP.  
- **I/O Expansion**: Connects to external PLCs or HMIs for automated production line integration.  
**User-Friendly Operation**  
- Optional **7-inch touchscreen** for quick parameter setup and real-time monitoring.  
- Built-in **fault diagnostics** and **historical data logging**.

| **Maintenance**   | Modular design, easy fault tracing   | Complex system, difficult troubleshooting |
**6. Important Notes**  
**Selection Tips**:  
- Confirm **material type** (e.g., metal foil, film, paper) and **maximum tension range**.  
- Select compatible **sensor type** (encoder/Load Cell).  
**Installation Requirements**:  
- Avoid vibration and electromagnetic interference (e.g., keep away from high-power inverters).  
- Ensure **shielded grounding** of sensor cables to prevent noise.  
**Configuration & Optimization**:  
- Use **auto-tuning** for quick PID parameter matching.  
- Advanced parameter configuration via **PC software (TB-Configurator)**.
