Siemens 6SL3120-2TE15-0AA3 — Dual-Axis Servo Drive Module | SINAMICS S120 Booksize Platform
Engineering Background
The SINAMICS S120 drive family is Siemens’ flagship multi-axis servo and vector drive platform, engineered for high-dynamic motion control in demanding industrial environments. The Booksize form factor enables compact, rail-mounted multi-axis configurations with shared DC-bus architecture, reducing cabinet footprint and simplifying energy recovery across axes.
Product Positioning
The 6SL3120-2TE15-0AA3 is a Double Motor Module within the SINAMICS S120 Booksize series, rated at 5 A per axis (2×5 A). It is designed to simultaneously control two servo or induction motors from a single booksize unit, making it the preferred choice for gantry systems, dual-spindle machines, and synchronized multi-axis applications where space and cost efficiency are critical.

Engineering Advantages
- Dual-Axis in One Slot — controls two independent motor axes from a single booksize module, halving the required drive slots versus single-axis alternatives
- Shared DC Bus Architecture — enables regenerative energy exchange between axes, reducing net energy consumption and eliminating braking resistors in balanced systems
- DRIVE-CLiQ Integration — plug-and-play digital communication with Siemens servo motors and encoders; automatic parameter identification eliminates manual commissioning errors
- Seamless SINUMERIK / SIMOTION Integration — native compatibility with Siemens CNC and motion controllers via PROFIBUS/PROFINET
- Compact Booksize Form Factor — minimizes panel space; supports high-density multi-axis configurations up to 6 axes per line module
- Proven Field Reliability — SINAMICS S120 platform deployed in millions of axes globally across automotive, aerospace, and precision manufacturing
System Architecture & Signal Flow
The 6SL3120-2TE15-0AA3 operates within the SINAMICS S120 Booksize drive line as follows:
- AC Supply → Line Module (ALM/SLM/BLM) — rectifies mains supply to regulated DC bus voltage
- DC Bus → Double Motor Module (6SL3120-2TE15-0AA3) — receives DC bus power; internal IGBT inverter generates variable-frequency AC output for each axis independently
- DRIVE-CLiQ Daisy Chain — Control Unit (CU320-2) communicates with each module via DRIVE-CLiQ for real-time torque/speed/position commands and feedback
- Motor Output (X1 / X2) — two independent 3-phase outputs connect to servo or induction motors with encoder feedback looped back via DRIVE-CLiQ or separate encoder interface
Sourcing & Quality Verification
- All units sourced from authorized industrial surplus channels and verified OEM supply chains
- Each module undergoes visual inspection, label verification, and functional pre-shipment testing
- Batch codes (0100-20458 / 0090-04210 / NDP-20BST) are cross-referenced against Siemens production records for authenticity

Technical FAQ
Q: Is the 6SL3120-2TE15-0AA3 compatible with SINAMICS S120 Chassis format?
A: No. This is a Booksize module and is only compatible with the S120 Booksize line, including ALM, SLM, and BLM line modules in booksize format.
Q: Can this module drive induction motors as well as servo motors?
A: Yes. The S120 platform supports both servo control (with encoder feedback via DRIVE-CLiQ) and vector control for standard induction motors.
Q: What Control Unit is required?
A: The CU320-2 DP or CU320-2 PN is the standard Control Unit for S120 Booksize configurations. The module connects via DRIVE-CLiQ daisy chain.
Q: Is firmware upgrade required after installation?
A: Siemens recommends matching firmware versions across all S120 components. Please verify the CU320-2 firmware version against the module’s hardware revision before commissioning.
Q: Do you provide export documentation for customs clearance?
A: Yes. Commercial invoice, packing list, and HS code declaration (HS 8537.10) are provided with every shipment.
