When developing this new series of frequency converters , we placed the emphasis on simplicity – in every respect. So that you can quickly integrate SINAMICS G120X into your drive application.

• Simple ordering (see the ordering systematics at the bottom)
  
• Simple integration into existing applications
• Simple commissioning (using the multi-color IOP-2 operator panel or Smart Access Module)
• Simple operation, setup and settings
• Simple connection to the Cloud using SINAMICS CONNECT 300
• Simple maintenance: SINAMICS G120X indicates when service is required (using the Analyze MyDrives MindSphere application)
• Simply flexible: SINAMICS G120X can be operated with any motor – but most effectively with Siemens synchronous-reluctance motors

We have done a lot to adapt the reliability and the ruggedness of the SINAMICS G120X to address globally increasing customer requirements. This means that the frequency converter  always operates with a high degree of stability – even during line supply fluctuations. To reduce harmonics, up to a power of 250 kW, devices have an integrated DC link reactor.

SINAMICS G120X is rugged and can operate in almost any environment: its operating temperature extends from -20°C up to 60°C (depending on the exact version). The converter complies with IP20 with an option for IP21 in UL open type. Coated modules are standard, 3C3 pollutant resistance is optionally available.

In addition, a comprehensive service portfolio is available to increase the availability and operation of the system. For the SINAMICS G120X, there is the option of an extended warranty up to 7 ½ years, various migration services and digitalization services.

To be both effective and cost efficient – these are key criteria for ideal converter  operation. Both aspects have huge significance when it comes to state-of-the-art drive applications. The features with which we have maximized the efficiency of SINAMICS G120X have been appropriately optimized.
The frequency converters  have an efficiency exceeding 98%. The flexibility of the converters  when selecting an appropriate motor is also a big plus: The converter  allows high-efficiency motors to be used for maximum energy-saving operation. For low dynamic loads, the ECO mode ensures the best possible performance and lowest losses for low dynamic loads. It also optimizes the output power to reduce the energy consumption of the driven load.
The bypass function* allows the motor to be switched between converter  and line operation to reduce energy consumption. The energy/flow calculator calculates energy saving and the flow value without requiring the installation of an external meter.
