The Siemens 6SL3130-6AE15-0AB1 is a Smart Line Module (SLM) belonging to the SINAMICS S120 drive family. It serves as the regulated infeed unit that supplies the DC link for connected Motor Modules. This module features a regenerative capability, returning excess energy to the mains supply, improving overall system efficiency.
Input voltage: 380 – 480 V 3-phase AC, 50/60 Hz
Rated power: 5 kW (continuous), 9 kW (peak for 3s)
Rated current: 9.2 A
DC link voltage: 600 – 720 V DC (regulated)
Regenerative feedback: Yes, fully controlled
Integrated line filter: Class A (for industrial environments)
The Smart Line Module features a diode bridge with integrated IGBT for regenerative braking, unlike the Basic Line Module which cannot feed back energy. It maintains a stable DC link voltage regardless of load variations, enabling high dynamic performance for servo motors. The module includes a pre-charging circuit to limit inrush current.
Built-in protection includes overvoltage, undervoltage, overcurrent, short-circuit, and heatsink overtemperature. The module provides status signals via a 3-pin terminal block: ready, alarm, and fault. An internal fan ensures forced cooling; fan speed is controlled based on load.

The SLM is controlled by the SINAMICS S120 Control Unit (CU310 or CU320) via the DRIVE-CLiQ interface. The module transmits real-time DC link voltage and current data to the CU for coordinated operation with Motor Modules. No separate programming is required; parameters are set in the Control Unit.
Dimensions (H x W x D): 270mm x 80mm x 165mm. Weight: 2.3 kg. Mounting: Booksize format for side-by-side assembly on a mounting plate or DIN rail adapter. The module requires a minimum clearance of 80mm above and below.
Operating temperature: 0°C to +40°C (derate above 40°C to 80% of rated power). Storage temperature: -40°C to +70°C. Humidity: 5-95% non-condensing. Altitude: up to 1000m without derating; up to 2000m with 10% derating per 500m.
CE, UL, cUL, EAC, and RoHS compliant. The module meets IEC 61800-3 for EMC and IEC 61800-5-1 for safety. It is designed for pollution degree 2 environments.
The 6SL3130-6AE15-0AB1 is used in SINAMICS S120 drives for machine tools, printing presses, packaging machinery, and high-performance conveyors requiring dynamic braking and energy recovery.
Connect the AC mains input to terminals L1, L2, L3 via a suitable line contactor. The DC link output (DCP/DCN) connects directly to the Motor Module(s). Use shielded cables for DRIVE-CLiQ to avoid interference.
The Siemens Smart Line Module 6SL3130-6AE15-0AB1 provides a compact, efficient front-end for SINAMICS S120 multi-axis systems, combining reliability, regenerative capability, and ease of integration.
