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**.

**5. Competitive Advantages**
| **Feature** | **TB820V2** | **Traditional PLC + Inverter Solution** |
|------------------|--------------------------------------|-----------------------------------------|
| **Control Accuracy** | ±0.5%, optimized for tension control | Lower accuracy (±2-5%), programming-dependent |
| **Response Time** | Millisecond-level dynamic adjustment | Limited by PLC scan cycles |
| **Setup & Debugging** | Pre-loaded tension algorithms, simplified parameter wizard | Requires custom logic development |
| **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)**.
