The Sinamics G120C inverter from Siemens is now also available with Profinet communication. The compact device is designed for industrial environments worldwide. It is suitable for the operation of pumps, compressors, fans and mixers and extruders; and also for conveyors and simple handling machines. The target group includes mechanical engineering companies (OEM) and distributors.


Siemens Drive Technologies Division is adding Profinet to its compact Sinamics G120C inverter for even greater communication versatility. Profinet now complements the Profibus, USS/Modbus RTU and CAN options already available to provide more enhanced efficiency and performance, enabling faster exchange of data for high-performance motion control applications. In addition, standard Ethernet communication and Profinet communication can be used in parallel.

The compact inverter offers the highest power densities in its class and lines up directly without loss of performance. Compared to conventional systems available on the market, the converter requires up to 30 percent less installation space and provides up to 40 percent higher power density. Plug-in terminals make for fast installation, while a memory card slot enables fast series commissioning.

Each G120C comes with 'Safety Integrated' from Siemens as standard to ensure safe drive shutdown. A dual safety input is factory-fitted to accomplish Safe Torque Off (STO function) without the need for connecting external devices. The G120C encompasses all proven control technologies from the Sinamics platform. The sensorless vector mode enables precise, cost-effective control for energy-optimized operation of induction motors.

The Sinamics G120C inverter in the rated output range from 0.55 to 18.5 kW sets new standards in its class in terms of compact design, quick commissioning, straightforward operation and high functional integrity. It has been optimized specially for use in small control cabinets located directly at the production machines, where simple speed-controlled drives with a high power density and space-saving design are often required.
