Siemens 6SL3120-2TE21-0AD0 SINAMICS S120 Double Motor Module 2x9A 400V

Dual‑axis motor module for SINAMICS S120 multi‑axis drive systems, converting 600V DC link voltage into 400V three‑phase output to independently control two servo motors in high‑performance industrial automation.

The Siemens 6SL3120‑2TE21‑0AD0 is a booksize double motor module within the SINAMICS S120 drive family. It accepts a DC link input range of 510–720V DC (nominal 600V DC) and provides 3‑phase 400V output with 9A per channel (27A max), powering two motors from a single unit for space‑saving cabinet layouts. The module features internal forced‑air cooling, optimized pulse sampling for enhanced servo performance, extended Safety Integrated functions (STO), and includes a DRIVE‑CLiQ cable for automatic configuration with a CU320‑2 Control Unit.

Applications

• Multi‑axis machine tools, printing presses, and packaging equipment

• Dual‑arm robots and synchronized conveyor systems

• High‑dynamic pick‑and‑place applications
