Siemens 6SL3220-1YE12-0AF0 Variable Frequency Drive for SINAMICS G120X

The Siemens 6SL3220-1YE12-0AF0 (6SL3220-1YE12-0AF0) is an industrial variable frequency drive designed for use within the Siemens SINAMICS G120X drive series. Engineered primarily for infrastructure and process applications such as pumps, fans, and compressors, this frequency converter provides efficient and precise speed control for three-phase AC induction motors. It regulates motor operation by converting incoming line power to a variable-frequency output, optimizing energy consumption and process performance across continuous-duty industrial installations. The unit operates on a three-phase AC supply voltage ranging from 380 V to 480 V AC and features an IP20 open-type protective enclosure suitable for control cabinet installation. It incorporates integrated industrial communication interfaces, supporting networked automation environments such as PROFINET or EtherNet/IP for seamless integration with programmable logic controllers and distributed control systems. With a shipping weight of 10 kg, the drive is engineered to deliver reliable motor protection, thermal management, and dynamic control in heating, ventilation, air conditioning, water management, and general industrial automated facilities.
