• Product Overview

  The 6SL3120-1TE28-5AA3 is a single motor module for Siemens SINAMICS S120 modular drive system. It works together with S120 line modules to convert DC bus power into variable frequency AC power to drive synchronous/asynchronous servo motors and spindle motors.

  The DRIVE-CLiQ bus realizes high-speed communication between the module, encoder and controller. It supports rich safety functions for machine safety requirements. Internal forced air cooling ensures stable continuous operation under heavy load. Automation engineers widely adopt this module for new machine assembly and spare replacement for existing S120 motion control systems.
