So that your drive application is always availableWe 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. |
![]() | So that your drive application is cost effectiveTo 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. * Bypass function is only supported on induction motors |

SIMATIC S7-1500 CPUs – The heart of the controller system
The central processing units (CPU) are the heart of the SIMATIC S7-1500 PLC. They execute the user program and network the controller with other automation components. Thanks to numerous innovations, the CPUs of the SIMATIC S7-1500 deliver the ultimate plus in productivity and efficiency.
Scalability, performance and usability
The signal modules or peripheral modules of the SIMATIC S7-1500/ET 200MP form the interface between the controller and the process. Via the connected sensors, the controller records the current process status and triggers corresponding reactions of the actuator. The digital and analog modules provide exactly the inputs/outputs that are required for the respective task. They can be used both centrally, i.e. directly at the SIMATIC S7-1500 CPU, and decentrally in the SIMATIC ET 200MP IO system. Analog modules possess expanded functions like oversampling or clock synchronism.
Technology Modules (TM) – The specialists in the system
Technology modules which can be used either centrally in the SIMATIC S7-1500 or decentrally in the SIMATIC ET 200MP IO system offer signal preprocessing close to the hardware for extremely fast counting and measuring as well as precise position detection for incremental and SSI absolute encoders. The intuitive parameterization and efficient programming is done by technology objects in the TIA Portal. A fast reaction to internal or external incidents and counter values is supported by various process alarms. The behavior of the TM modules regarding a “CPU stop” can be parameterized.
More flexibility and performance
Interfaces for communication via PROFINET and in part PROFIBUS DP as well are already integrated in the CPUs. Communication modules increase the communication capabilities of the S7-1500 / ET 200MP providing additional functions or additional interfaces and increase the flexibility and performance of automation solutions with SIMATIC S7-1500 / ET 200MP. Additional interfaces enable realization of complex automation structures or process optimization through connection to the enterprise management level.
Easy entry
Everything for an easy start: The SIMATIC S7-1500 Starter Kit with the compact CPU for standard applications or the technology CPU for extended motion control requirements. Utilize our Starter Kits to program, install, connect and commission quickly and easily.
60 years of SIMATIC anniversary edition:
In 2018 Siemens celebrated 60 years of SIMATIC. On the occasion of this anniversary every SIMATIC S7-1500 Starter Kit is now extended with TIA portal options.
In addition to STEP 7 Professional, the licenses for the option packages SIMATIC ProDiag S7-1500 for 250supervisions and SIMATIC OPC UA S7-1500 Small for secure, reliable communication independent of vendor and platform are currently included.

The flat IOP-2 Intelligent Operator Panel allows fast local setup, fault diagnostics, and intuitive operation of SINAMICS G frequency converter series and simplifies the adjustment of settings during operation. The intuitive central multifunctional sensor control panel supports users with selectable settings.
There are three methods of using the IOP-2: Directly plugging it into the control unit of the converter, mounting in the door for operation outside the control cabinet, and as an IOP handheld unit for wired operation in difficult-to-access locations.
The IOP-2 is available as an additional option for the SINAMICS frequency converter series G120, G120X, G120XA, G120P, G120C, G120D, G110M and SIMATIC ET 200pro FC-2
