Servo Controller | Siemens | 6SL3120-1TE26-0AC0 6SL3 120-1TE26-0AC0 S120 SINGLE MOTOR MODULE

Product Description
The Siemens 6SL3120‑1TE26‑0AC0 is a book‑size Single Motor Module for the modular SINAMICS S120 drive family. Supplied from a 600 V DC bus, it delivers three‑phase 400 V AC to the motor with a continuous output current of 60 A. Integrated pulse‑pattern optimisation, sensor‑less vector control and full support for the SINAMICS “Safety Integrated” functions make it suitable for both standard and safety‑relevant motion tasks in machinery, handling systems and production lines. Designed for compact cabinet installation, the module uses forced‑air internal cooling and features the DRIVE‑CLiQ interface for seamless connection to CU‑320/310 control units.
