SIEMENS 6SL3210-1KE15-8UF2 Single Motor Module 2.2kW – SINAMICS S120 Series
When a SINAMICS S120 drive axis goes down on the production floor, the entire coordinated motion sequence stops — CNC machining centers stall mid-cycle, textile winding lines lose tension synchronization, and packaging robots freeze in position. Every minute of unplanned downtime translates directly into scrapped batches, missed delivery windows, and escalating maintenance costs. The SIEMENS 6SL3210-1KE15-8UF2 Single Motor Module is the precision power electronics heart of that axis, and sourcing a verified replacement unit quickly is non-negotiable for restoring production.
Within the SINAMICS S120 booksize power module family, the 6SL3210-1KE15-8UF2 occupies the compact 2.2 kW output class — the workhorse rating for auxiliary axes, conveyor drives, and positioning spindles where space on the drive rail is at a premium. SINAMICS S120 is Siemens’ flagship multi-axis servo and vector drive platform, deployed across automotive body-in-white lines, semiconductor fabs, printing presses, and wind turbine test rigs worldwide. This specific module interfaces directly with the S120 Control Unit (CU320-2, CU310-2) via DRIVE-CLiQ, enabling fully digital, closed-loop torque and speed control without external encoder conditioning hardware.

Key Features & Benefits
- DRIVE-CLiQ Digital Interface: Eliminates analog signal noise; enables automatic motor/encoder identification and seamless integration into the S120 drive line-up.
- Compact Booksize Form Factor: Maximizes drive cabinet density — critical for retrofits where panel space is constrained.
- Closed-Loop Vector & Servo Control: Supports both induction motor (V/f, sensorless vector) and synchronous servo motor control modes from a single hardware platform.
- Safe Torque Off (STO) Ready: Integrated SIL 2 / PLd safety function reduces external safety relay hardware and simplifies machine safety certification.
- Energy Recovery: When paired with an Active Line Module, regenerative braking energy is fed back to the DC bus, reducing net energy consumption.
- Hot-Swap Capable: Booksize modules can be replaced without disturbing adjacent modules on the drive rail, minimizing maintenance downtime.
- Scalable Architecture: Identical control philosophy across the S120 power range (0.12 kW – MW class) protects engineering investment and simplifies spare-parts management.

Frequently Asked Questions
Q: What is the difference between 6SL3210-1KE15-8UF2 and other 6SL3210-1KE1x variants?
A: The 6SL3210-1KE series covers the SINAMICS S120 booksize Single Motor Module range. The digits following “1KE” encode the output current/power class. The 6SL3210-1KE15-8UF2 is rated at 2.2 kW. Other variants in the same family cover different power ratings (e.g., 1KE11 = 0.75 kW, 1KE21 = 3 kW). Always verify the exact part number for your axis power requirement.
Q: Can this module be used as a direct replacement without re-commissioning?
A: In most cases, a like-for-like hardware replacement (same part number, same firmware major version) can be performed by restoring the drive parameters from a backup file via STARTER or Startdrive. However, Siemens recommends verifying firmware compatibility and re-running motor identification if the motor data set was not backed up.
Q: Do you supply new, refurbished, or used units?
A: We supply new surplus, factory-refurbished (with Siemens or authorized service center certification), and tested-used units depending on availability. Stock condition is clearly stated in the quotation. Contact us to specify your requirement.
Q: What is the lead time for the 6SL3210-1KE15-8UF2?
A: Lead time depends on current stock status. In-stock units ship within 2–3 business days. For sourced units, typical lead time is 7–15 business days. Emergency orders are handled on a priority basis — contact us directly for urgent requirements.
Q: Can you provide export documentation for customs clearance?
A: Yes. We provide a commercial invoice, packing list, and certificate of origin as standard. Additional documentation (e.g., EUR.1, Form A, or specific country certificates) can be arranged upon request.
Q: Is the 6SL3210-1KE15-8UF2 compatible with TIA Portal / Startdrive?
A: Yes. SINAMICS S120 modules are fully supported in Siemens TIA Portal via the Startdrive engineering tool (V14 SP1 and above), as well as the legacy STARTER software. Ensure your Startdrive version supports the firmware version installed on the module.
