Specification

SEODescription

The SINAMICS S120 Drive Module, specifically the 6SL3210-1PB21-8AL0 Power Module, is a 380-480V three-phase booksize motor drive designed for high-performance industrial applications. It features a compact, modular design with integrated DC link components, supporting direct connection to up to six Motor Modules for multi-axis systems. The module operates within a voltage range of 380–480V AC (±10%) and a temperature range of 0–40°C, ensuring reliability in automation, manufacturing, and material handling industries. Key interfaces include Drive-CLiQ for seamless communication with control units and optional PROFIBUS/PROFINET integration. Notable advantages include energy-efficient regenerative capability, scalable power up to 18.5 kW, and robust thermal management. However, its complexity may require specialized configuration expertise, and the booksize format limits physical expansion compared to chassis-based systems.
