🧠 System Role
In a SINAMICS S120 architecture:
Control Unit (CU)
→ controls
Active Line Module (6SL3130-7TE25-5AA3)
→ generates regulated DC bus power for
Motor Modules
→ drive
servo motors
The Active Line Module acts as the central power infeed and regenerative energy management unit for the complete drive system.
🔋 Advantages of Active Line Technology
- Regenerative energy returned to the electrical grid
- Reduced heat generation compared to brake resistor systems
- Near-unity power factor
- Stable DC bus voltage independent of mains fluctuations
- Lower harmonic distortion
- Higher energy efficiency in dynamic servo applications
These advantages make Active Line Modules common in advanced CNC and motion-control installations.
🏭 Typical Applications
- CNC machine tools
- Robotics systems
- Packaging machinery
- Printing and converting equipment
- Material handling systems
- Multi-axis industrial automation
- SINUMERIK and SIMOTION motion control systems
