SIEMENS 6SL3353-3AG36-8BA0 – High-Power Motor Module | SINAMICS S120 Platform
Engineering Background
The SINAMICS S120 drive system is Siemens’ flagship multi-axis servo and vector drive platform, engineered for demanding motion control applications in machine tools, printing presses, packaging lines, and heavy industrial automation. The S120 architecture separates the infeed (Active Line Module) from the motor-side power conversion (Motor Modules), enabling modular, scalable drive trains with shared DC bus topology.
Product Positioning
The 6SL3353-3AG36-8BA0 is a Booksize format Motor Module within the SINAMICS S120 family, rated for high-current servo and induction motor drives. It is designed for OEM machine builders and system integrators who require deterministic torque response, precise speed regulation, and seamless integration with SIMATIC S7 / TIA Portal engineering environments. Konmask.com supplies this module as verified OEM hardware with full traceability documentation.

Proven Application Environments
- CNC Machine Tools – High-dynamic servo axes requiring sub-millisecond torque response and tight speed regulation
- Printing & Converting Machines – Register-accurate multi-axis synchronization via DRIVE-CLiQ and PROFINET
- Packaging Lines – Continuous duty cycles with frequent acceleration/deceleration profiles
- Extruders & Winders – Tension control and speed-following applications with high inertia loads
- Test Benches & Dynamometers – Four-quadrant operation with regenerative energy feedback
- Crane & Hoist Systems – Safe torque off (STO) and safety-integrated functions
Engineering Advantages
- DRIVE-CLiQ Ecosystem – Single-cable connection to motors, encoders, and sensors eliminates wiring complexity and enables automatic component identification
- Shared DC Bus Architecture – Energy regenerated by braking axes is consumed by motoring axes, reducing net energy consumption by up to 30%
- Safety Integrated (SIL 2 / PLe) – On-board STO, SS1, SLS, SDI functions without external safety relays
- TIA Portal Integration – Full parameterization, diagnostics, and commissioning via STARTER or TIA Portal Startdrive
- Scalable Performance – Booksize format allows dense cabinet mounting; multiple modules share a single Line Module infeed
- Firmware Consistency – Compatible with SINAMICS S120 firmware V4.7 and above; backward-compatible parameter sets
System Architecture & Signal Flow
In a typical S120 Booksize cabinet, the Active Line Module (ALM) rectifies mains AC to a regulated DC bus (typically 600 V DC). The 6SL3353-3AG36-8BA0 Motor Module draws from this shared DC bus and inverts to variable-frequency, variable-voltage AC output to drive the connected motor. The Control Unit (CU320-2) communicates with the Motor Module via DRIVE-CLiQ at 1 ms cycle time, executing closed-loop speed and torque algorithms. Encoder feedback is routed directly through DRIVE-CLiQ from the motor’s Sensor Module Cabinet (SMC) or integrated encoder interface.
Signal flow: Mains AC → ALM → DC Bus → 6SL3353-3AG36-8BA0 → Motor → Load

Technical FAQ
Q: Is the 6SL3353-3AG36-8BA0 compatible with SINAMICS S120 CU320-2 DP/PN?
A: Yes. It connects via DRIVE-CLiQ and is fully compatible with CU320-2 DP and CU320-2 PN control units running firmware V4.7+.
Q: Can this module drive both synchronous servo motors and asynchronous induction motors?
A: Yes. The S120 Motor Module supports SERVO mode (for synchronous/PM motors) and VECTOR mode (for induction motors), selectable via parameter p0300.
Q: What is the DC bus voltage range?
A: Nominal 600 V DC from a matched Active Line Module. The module includes overvoltage and undervoltage protection with configurable thresholds.
Q: Does it support Safe Torque Off (STO)?
A: Yes. STO (SIL 2, PLe, Cat. 3) is integrated on-board without requiring an external safety option board.
Q: What is the lead time for this part?
A: Typically 3–7 business days for in-stock units. Contact us for current availability and expedited shipping options.
