Specification

SEODescription

The Siemens SINAMICS S120 Motor Module 6SL3210-1NE21-8AL1 is a 380-480V three-phase booksize inverter designed for dynamic industrial motor control. This drive unit operates within a 380-480V AC input range and integrates seamlessly with Siemens control units via DRIVE-CLiQ interfaces, supporting direct connection to encoder modules and power supplies. It lacks built-in digital I/O but enables high-speed communication through PROFIBUS or PROFINET protocols. With a compact design for space-constrained installations, it functions optimally in 0°C to 40°C environments, making it suitable for automation, CNC machinery, and material handling systems. Key strengths include precise speed regulation, regenerative braking capability, and modular scalability. However, it requires external control units for operation and has limited standalone functionality. Its robust construction ensures reliability in demanding industrial applications.
