Siemens 6SL3130-1TE24-0AA0 Smart Line Module for SINAMICS S120

The Siemens 6SL3130-1TE24-0AA0 is a Smart Line Module belonging to the SINAMICS S120 drive system family. This module is an active infeed unit that converts three-phase AC mains power into a regulated DC link voltage to supply multiple Motor Modules (inverters) in a common DC bus configuration. With a rated power of 24 kW and an input voltage range of 380-480 V AC, it is designed for high-performance industrial drive applications requiring regenerative energy feedback. The Smart Line Module features active line filtering, low harmonic distortion (THD < 3%), and a built-in brake chopper for dynamic braking. It is suitable for use in machine tools, printing presses, winders, and other demanding motion control systems.

Operation in SINAMICS S120 System

The 6SL3130-1TE24-0AA0 Smart Line Module operates as the central power supply for a multi-axis SINAMICS S120 drive system. It connects to the three-phase mains supply and generates a regulated DC link voltage. Multiple Motor Modules (up to 200 kW total) can be connected to the same DC bus to share power and regenerative energy. The active infeed technology allows the module to feed back braking energy into the mains supply, significantly reducing energy consumption in applications with frequent deceleration. The built-in brake chopper handles short-term overvoltage when the mains cannot absorb regenerative energy.

Configuration and Integration

The module is configured via Siemens STARTER or SINAMICS Startdrive software (TIA Portal). DRIVE-CLiQ cables automatically identify the module to the Control Unit. Parameters include mains type, line voltage, current limits, and braking resistor settings. The module supports PROFIBUS or PROFINET communication through the Control Unit. LED status indicators provide diagnostics: ready, fault, DC link active, and brake chopper activity.

Applications

The 6SL3130-1TE24-0AA0 is used in multi-axis drive systems for machine tools (milling, turning centers), packaging machines (flow wrappers, cartoners), printing presses (web tension control), winders and unwinders, and handling systems (robots, pick-and-place). Its regenerative capability is particularly beneficial for applications with frequent stop-start cycles or overhauling loads, such as cranes, centrifuges, and test stands.

Installation and Wiring

Mount the module vertically on a DIN rail or backplate. Provide 100 mm clearance above and below for airflow. Connect the three-phase mains to terminals L1, L2, L3. Connect the DC link output to the Motor Modules via busbars or cables. Connect the external braking resistor to terminals R+ and R- (if used). Connect DRIVE-CLiQ cables to the Control Unit. Use shielded cables for all connections. Earth the module via the PE terminal. Ensure the mains supply has appropriate fusing (e.g., 63A). The module requires an upstream line reactor (recommended) for harmonic compliance.

Protection and Maintenance

The module includes overvoltage, undervoltage, overcurrent, and overtemperature protection. A red LED indicates a fault; the fault code can be read via the Control Unit. The internal fan has a typical life of 40,000 hours; replace it if noisy or failed. No other user-serviceable parts. Periodically clean the air intake and exhaust vents.

Conclusion

The Siemens 6SL3130-1TE24-0AA0 Smart Line Module provides efficient, regenerative power conversion for SINAMICS S120 multi-axis drive systems. Its active infeed, low harmonics, and built-in brake chopper make it a suitable choice for high-performance industrial motion control applications.
