SINAMICS G120 Drives



About SINAMICS Drives Family

Whether it’s a matter of efficient pumping, ventilating and compressing, or precise movement, processing, or machining, the number of application areas for frequency converters is almost endless. So it’s good that there is one family of drives for all of these areas that fulfills every requirement perfectly: SINAMICS. Our portfolio represents uniform engineering, extremely high efficiency and convenient operation.

The Right Drive All the Time

Siemens innovative design provides the right frequency converter for every drive application. Products range from basic drives, dynamic servo drives for Motion Control to medium voltage drives — plus tailored solutions. SINAMICS is the worlds largest drives family for frequency converters.

About SINAMICS G120 Drives

SINAMICS G120 is a modular, space-saving, and rugged vector drive. Irrespective of whether pumping, compressing, moving or processing: SINAMICS G120 is the universal drive to address the widest range of requirements.

Why SINAMICS G120 Drives

Its modular design and wide range of power ratings extending from 0.55 kW up to 250 kW ensures that you can configure the optimum inverter for your particular application.


The modular SINAMICS G120 is suitable for applications with medium continuous motion or basic discontinuous motion requirements in:

  • Pumping/ventilating/compressing
  • Moving
  • Processing

Features & Benefits

Built-in DC Reactor

Siemens G120 Drives have built-in DC reactors on all 600V, 480V (25HP and up), and 240V (15HP and up). This eliminates the need for external line reactors and also reduces footprint in your enclosure. Additional advantages are lower Harmonic Distortion and longer motor distances without the need for a load reactor (up to 75 meters).

Easy to use Intelligent Operator Panel and USB cable

The operator panel is extremely simple to use, with built-in application wizards, commissioning tools and diagnostic capabilities. If you require more in depth commissioning, you can use the USB interface and the complimentary Siemens software to connect to the VFD and fine-tune the parameters.

E.B. Horsman Value-Adds

i. Turn-key solutions – pre-built VFD panels with accessories and commissioning
ii. Sizing from simple to complex applications with variable duty cycles
iii. On-site troubleshooting and technical support


The G120 drives are modular with separate Control Unit, Power Module and Operator Panel. The Power Module contains all the power electronics and IGBTs, whereas the Control Unit contains the intelligence, I/O and Communication ports. This configurations opens up a world of comfort in terms of maintenance, cost saving and shorter downtimes. Your VFD failed due to a power surge? Simply replace the Power Module and Keep the Control Unit intact, saving you the hassle of rewiring and reprogramming. Did you know that you can use any Control Unit for any Power Module size?

Space - s a v i n g , Safe, and Flexible, everything you want in your VFD

Communication Protocol Flexibility

The G120 drives can talk Profinet, Ethernet/IP, Profibus DP, BACnet, Modbus and CANopen
