Use of the G120X for example, as a well pump


Where are the SINAMICS G120X variable frequency drives from Siemens used?

With the variable frequency drive G120X from the SINAMICS family, Siemens has developed a series that optimally regulates water and air pushing motors.

This makes the VFD's particularly suitable for pumping and ventilation applications in the infrastructure sector. Additionally, heating, ventilation and air conditioning applications in building automation are suitable applications for the G120X.

SINAMICS G120X – ready for the future thanks to powerful features

With the award-winning product features, Siemens VFD's are up to the challenge. Even under harsh conditions, they work reliably and efficiently.

The G120X variable frequency drives are characterized by their robust housing, thanks to drip water protection and lacquered assemblies. The integrated intermediate throttle provides for stable operation under all network conditions.

Thanks to application-specific energy efficiency features such as flux reduction, Keep Running Mode for maximum system availability without manual intervention, Pump Boost for efficient pump performance, or Eco mode for a particularly energy-saving operation, the G120X variable frequency drives from Siemens are also prepared for the demands of the future. Last but not least, the communication via PROFINET-PN/Ethernet IP and the Cloud connection option with SINAMICS CONNECT 300 also contribute to future-proof networking.

SINAMICS G120X for the future

Furthermore, the safety aspect was also taken into account, because the G120X variable frequency drives from Siemens have the certified integrated STO SIL3 safety hardware Safe Torque Off (STO) via terminals that protect machines, processes and people.

The powerful variable frequency drives are available in various sizes with different power ranges and work with all voltages and supply networks. This covers a wide range of applications.

Thanks to the sophisticated IOP-2 operator panel and the Smart Access Modules the VFD's are easy to parameterise and operate.

The G120X series is compatible with the SIMATIC S7-1200, S7-1500, and S7-400 controllers.


With the SINAMICS G120X, you can tame the future of the elements of water and air for versatile applications in the infrastructure industry as well as building automation. What are you waiting for? Order the suitable G120X variable frequency drive for you today. The future begins now!
