SIEMENS 6SL3120-1TE Single-Axis Motor Module – SINAMICS S120 Series
When a motor module fails on the production floor, the entire drive axis goes offline — CNC machining centers halt mid-cycle, robotic arms freeze in position, and conveyor systems grind to a stop. Every minute of unplanned downtime translates directly into lost output and costly emergency maintenance. The SIEMENS 6SL3120-1TE Single-Axis Motor Module is the precision power electronics component that keeps your SINAMICS S120 drive system running at full capacity, delivering regulated DC-link power to servo and induction motors with the reliability that mission-critical industrial environments demand.
Within the SINAMICS S120 modular drive family, the 6SL3120-1TE occupies the single-axis position — purpose-built for applications requiring independent axis control with high dynamic response. As part of Siemens’ globally dominant S120 platform, this module is deployed across tens of thousands of installations in automotive manufacturing, aerospace machining, packaging lines, and precision motion systems worldwide. Its booksize form factor integrates seamlessly into S120 drive line-ups, sharing the DC bus with infeed modules and other motor modules for maximum energy efficiency.

Frequently Asked Questions
- Q: What is the difference between 6SL3120-1TE (single-axis) and 6SL3120-2TE (double-axis) motor modules?
- A: The 1TE variant controls one motor axis independently, while the 2TE variant drives two axes from a single module housing — reducing cabinet space for multi-axis machines.
- Q: Can the 6SL3120-1TE be used without a SINAMICS S120 Control Unit?
- A: No. The motor module requires a SINAMICS S120 Control Unit (e.g., CU320-2) connected via DRIVE-CLiQ for parameterization and closed-loop control.
- Q: Do you supply the specific sub-variant I need (e.g., 6SL3120-1TE21-0AA3)?
- A: Yes. Please provide your full part number when submitting an inquiry and we will confirm availability and lead time for your exact variant.
- Q: What warranty do you offer?
- A: We offer a 12-month warranty against manufacturing defects on all units supplied. Terms are detailed in our quotation documentation.
- Q: Can you provide an export declaration or customs documentation?
- A: Yes. We provide commercial invoices, packing lists, and certificates of origin as required for international customs clearance.
