The 6SL3120‑1TE21‑8AD0 is a SINAMICS S120 book‑size D‑type single‑axis motor module from Siemens. It is a core power component of the S120 high‑performance drive system. It converts DC‑bus voltage into adjustable three‑phase AC output to drive synchronous and asynchronous servo motors. With internal air cooling, optimized pulse patterns and extended Safety‑Integrated safety functions, it delivers ultra‑high dynamic response and accurate speed, torque and position control, widely used for multi‑axis high‑precision motion‑control equipment.
