Servo Controller | Siemens | 6SL3120-1TE28-5AA3 6SL3 120-1TE28-5AA3 SINAMICS S120 Double Motor

Product Description: Siemens 6SL3120-1TE28-5AA3

The Siemens 6SL3120-1TE28-5AA3 is a single-axis motor module from the SINAMICS S120 drive system, designed to control high-power servo or induction motors with dynamic precision. It delivers up to 85 A continuous output current from a 600 V DC link, making it suitable for high- torque, high-inertia applications. As part of the Booksize Frame Size E category, it is optimized for side-by-side cabinet mounting with effective heat dissipation via internal air cooling. This module is used in conjunction with SINAMICS S120 line modules and control units (CU), and communicates via DRIVE-CLiQ. It is ideal for machine tools, packaging machines, and other multi-axis industrial automation systems requiring fast acceleration and precise speed or position control.
