Multi-Axis Servo Drive Solution — SIEMENS 6SL3420-2TE11-7AA1 | SINAMICS S120
Where This Product Is Used
The SIEMENS 6SL3420-2TE11-7AA1 Double Motor Module is a booksize-format power output stage designed for demanding multi-axis motion control applications. Engineers specify this module wherever two servo axes must share a single drive slot, reducing cabinet footprint without sacrificing dynamic performance. Typical deployment environments include:
- CNC Machining Centers — simultaneous X/Y axis control with sub-millisecond torque response
- Industrial Robotics — dual-joint actuation in articulated arm and SCARA configurations
- Textile & Printing Machinery — synchronized feed and tension control across two motor axes
- Packaging Lines — coordinated pick-and-place and conveyor indexing
- Semiconductor & Electronics Assembly — precision positioning stages requiring matched axis performance
- Material Handling & Gantry Systems — dual-drive gantry synchronization for overhead cranes and transfer systems

Why Engineers Specify This Model
- Space Efficiency — One booksize slot drives two independent servo axes, cutting panel width by up to 40% versus single-axis alternatives.
- DRIVE-CLiQ Integration — Native Siemens DRIVE-CLiQ topology enables automatic motor identification, encoder parameterization, and real-time diagnostics without manual configuration.
- Matched Axis Performance — Both channels share the same DC bus, ensuring identical dynamic response and eliminating inter-axis voltage imbalance in synchronized motion profiles.
- Seamless SINUMERIK / SIMOTION Compatibility — Drop-in integration with Siemens CNC and motion controllers; no additional gateway hardware required.
- Proven Reliability — SINAMICS S120 platform is deployed in millions of axes globally across automotive, aerospace, and process industries.

Application-Specific FAQ
Q: Can the 6SL3420-2TE11-7AA1 operate both axes simultaneously at full rated current?
A: Yes. Both axes are independently controlled and can run at their rated continuous current simultaneously, provided the DC bus supply (Active Line Module) is sized accordingly for the combined load.
Q: Is this module compatible with third-party motors (non-Siemens)?
A: The module supports third-party motors via the standard encoder interface, but DRIVE-CLiQ automatic identification is only available with Siemens SIMOTICS motors. Manual parameterization is required for third-party motors.
Q: What is the difference between 6SL3420-2TE11-7AA1 and 6SL3420-2TE13-0AA0?
A: The 7AA1 variant is rated at 1.7 A continuous per axis; the 3-0AA0 is a higher-current variant. Selection depends on your motor’s rated current and peak torque requirements. Contact us for axis sizing support.
Q: Can I use this module with SIMOTION D or SINUMERIK 840D?
A: Yes. The 6SL3420-2TE11-7AA1 is fully compatible with SIMOTION D4x5-2 and SINUMERIK 840D sl / 828D control platforms via DRIVE-CLiQ.
Q: Do you provide warranty on this part?
A: All units sold through Konmask.com carry a 90-day functional warranty. Extended warranty and on-site support arrangements are available for project orders.
