SIEMENS 6SL3420-2TE15-0AA1 – Dual-Axis Motor Drive Module | SINAMICS S120 Booksize Platform
Engineering Background
The SINAMICS S120 series represents Siemens’ flagship multi-axis servo drive architecture, engineered for high-dynamic motion control in demanding industrial environments. The Booksize form factor enables compact, modular cabinet integration with shared DC-link topology, reducing wiring complexity and improving energy efficiency through regenerative braking across axes.
Product Positioning
The 6SL3420-2TE15-0AA1 is a Double Motor Module (DMM) within the SINAMICS S120 Booksize family, designed to independently control two servo or induction motor axes from a single module. With a rated output current of 5A per axis, it is optimally suited for light-to-medium duty multi-axis applications including CNC machine tools, packaging lines, textile machinery, and precision assembly systems. It operates in conjunction with a Control Unit (CU320-2 or CU310-2) and a Line Module via the shared DC bus.

Proven Application Environments
- CNC Machine Tools – Simultaneous dual-axis control for X/Y or spindle/feed configurations
- Packaging Machinery – High-speed coordinated motion for film feed and sealing axes
- Textile & Winding Equipment – Tension-controlled multi-axis winding with encoder feedback
- Printing Presses – Register-accurate web tension and impression cylinder drives
- Assembly Automation – Pick-and-place and conveyor indexing in multi-axis gantry systems
- Semiconductor & Electronics Manufacturing – Ultra-precise positioning in cleanroom-compatible enclosures
Engineering Advantages
- Shared DC Bus Architecture – Energy from decelerating axes is fed back to accelerating axes, reducing net power consumption by up to 30%
- DRIVE-CLiQ Integration – Plug-and-play encoder and motor identification eliminates manual parameter entry; supports Siemens SMC/SME encoder modules
- Dual-Axis Density – Two independent servo axes in one Booksize slot reduces cabinet footprint vs. two single-axis modules
- Scalable Switching Frequency – 4/8/16 kHz selection balances thermal performance against current ripple for motor protection
- Integrated Safety Functions – STO (Safe Torque Off) and SS1 (Safe Stop 1) via PROFIsafe or onboard terminals (SIL 2 / PLd)
- Seamless TIA Portal Integration – Full parameterization via STARTER, Startdrive, or SIMATIC S7 with DCC/EPOS function blocks
System Architecture & Signal Flow
The 6SL3420-2TE15-0AA1 operates within the SINAMICS S120 Booksize system as follows:
- Power Supply – AC mains → Line Module (Active/Smart/Basic Infeed) → shared 600 V DC bus
- DC Distribution – DC bus bar connects all Booksize modules in the cabinet row
- Motor Module – 6SL3420-2TE15-0AA1 draws from DC bus, inverts to variable-frequency 3-phase AC for each motor axis
- Feedback Loop – Motor encoder signals return via DRIVE-CLiQ to the Control Unit (CU320-2 DP/PN)
- Setpoint Channel – Speed/torque/position setpoints delivered from CU via DRIVE-CLiQ at 125 µs cycle time
- Safety Channel – STO/SS1 signals processed onboard or via PROFIsafe telegram 30/31

Technical FAQ
Q: Can the 6SL3420-2TE15-0AA1 operate as two independent axes simultaneously?
A: Yes. Each axis has its own DRIVE-CLiQ port, independent current controller, and separate motor output terminals. Both axes can run concurrently with independent speed/torque profiles.
Q: Which Control Units are compatible?
A: CU320-2 DP, CU320-2 PN, CU310-2 DP, CU310-2 PN. The module is parameterized as two separate Drive Objects within STARTER or Startdrive.
Q: What motor types are supported?
A: Synchronous servo motors (1FK7, 1FT7), asynchronous induction motors, and linear motors with appropriate encoder feedback via DRIVE-CLiQ or SMC20/SMC30 encoder modules.
Q: Is STO certification available for this module?
A: Yes. The integrated STO function is certified to SIL 2 (IEC 62061) and PLd Cat. 3 (EN ISO 13849-1). Safety certificate available upon request.
Q: What firmware version is required?
A: Firmware ≥ 4.7 SP3 recommended for full feature support. Compatible with SINAMICS S120 firmware up to current release (5.x).
Q: Can I replace a 6SL3420-2TE15-0AA0 with this unit?
A: The -0AA1 is the successor revision to -0AA0 with identical electrical specifications and improved EMC performance. Direct drop-in replacement; no parameter changes required.
