Product Description

The Siemens SINAMICS S120 Drive, model 6SL3111-3VE21-6EA1, is a high-performance Motor Module designed for industrial automation and precision motion control. This 6SL3111 Motor Module supports direct integration into multi-axis systems via a shared DC link, enabling seamless coordination with other modules. It operates within a voltage range of 380–480V AC (±10%) and is rated for ambient temperatures from 0°C to 40°C. The 3VE21-6EA1 Inverter features advanced diagnostics, PROFIBUS/PROFINET interfaces for real-time communication, and compatibility with vector-controlled motors. Widely used in manufacturing, robotics, and material handling, it offers exceptional dynamic response, modular scalability, and energy efficiency. However, complex configuration requires specialized expertise. The compact design lacks a built-in display or battery, relying on external control units for programming and monitoring.
