SIEMENS 6SL3350-6TK00-0BA0 – Active Line Module 16kW | SINAMICS S120 Booksize Platform
The SIEMENS 6SL3350-6TK00-0BA0 is a high-performance Active Line Module (ALM) from the SINAMICS S120 Booksize series, engineered for demanding industrial drive applications requiring clean power regeneration, ultra-low harmonic distortion, and bidirectional energy flow. Designed for procurement engineers specifying servo and vector drive systems in precision manufacturing, robotics, and process automation environments.
This module functions as the DC bus supply unit within a SINAMICS S120 multi-axis drive system, delivering regulated DC link voltage to connected Motor Modules while enabling regenerative braking energy to be fed back to the AC supply — reducing energy consumption and eliminating braking resistors in most applications.

System Architecture & Signal Flow
The 6SL3350-6TK00-0BA0 operates as the infeed module in a SINAMICS S120 Booksize drive line-up:
- AC Supply → Line Filter (optional) → Line Reactor → Active Line Module (this unit)
- ALM converts AC to regulated DC bus voltage (~600–750 V DC)
- DC bus is shared across all connected Motor Modules via busbars
- DRIVE-CLiQ daisy-chains ALM → Motor Modules → Encoders → Control Unit (CU320-2)
- Regenerated energy flows back: Motor Module → DC bus → ALM → AC grid
- Control Unit (CU320-2 DP/PN) manages the entire drive system via PROFIBUS or PROFINET

Technical FAQ
Q: Can the 6SL3350-6TK00-0BA0 operate as a standalone drive?
A: No. It is an infeed module and must be paired with SINAMICS S120 Motor Modules and a Control Unit (e.g., CU320-2). It does not directly control a motor.
Q: What line reactor is required?
A: Siemens recommends a 2% line reactor (e.g., 6SL3000-0BE21-6AA0) upstream of the ALM to protect against voltage spikes and ensure stable operation.
Q: Is a line filter mandatory?
A: The AFE topology inherently reduces harmonics. An additional EMC line filter may be required depending on local grid regulations (EN 61800-3 Category C2/C3).
Q: What firmware/software is needed for commissioning?
A: SINAMICS Startdrive (TIA Portal V16+) or STARTER V5.4+. DRIVE-CLiQ enables automatic topology detection.
Q: Can this module replace a Basic Line Module (BLM)?
A: Yes, with caveats. The ALM provides regeneration and lower harmonics vs. BLM, but requires a line reactor and has different DC bus voltage characteristics. Verify compatibility with your Motor Module firmware.
Q: What is the typical lead time?
A: In-stock units ship within 3–5 business days internationally. Contact us for current availability.
