SINAMICS G120XA, PN version, frame sizes FSA to FSJ, with IOP-2 Intelligent Operator Panel

Easy handling, utmost reliability, superior efficiency and advanced digitalization – Siemens offers an answer to these trends with the SINAMICS G120XA converter series. SINAMICS G120XA is an innovative and user-friendly converter series that has been specifically developed for applications performed in infrastructure environments such as water/wastewater, but also for tasks in building automation. In this context, the converter supports, for example, pump, fan and compressor applications through numerous integrated functionalities and combines these in one device for the target sectors.

The SINAMICS G120XA converter series is intended for driving pumps and fans or comparable passive loads with low dynamic requirements. With this converter series, regenerative energy can neither be fed back into the supply system nor dissipated via braking chopper and braking resistor.

The SINAMICS G120XA converter is an integrated and efficient drive solution for a wide range of tasks. The system allows convenient handling through optimized user interfaces: IOP‑2 Intelligent Operator Panel with graphic color display and the optional web server module SINAMICS G120 Smart Access – a WLAN-based web server solution. Thus, the SINAMICS G120XA fulfills the request for an easy and fast setup of the devices during the commissioning phase. Further, experienced users can use the full flexibility of a SINAMICS converter and adjust the relevant application to their requirements.

Totally integrated operation - this approach is also supported from ordering through to delivery. 
For example, all the major features of the converter are configured and displayed in the article number. The delivery includes the complete device - as configured - that means, the converter and the selected operator panel.

In addition, SINAMICS G120XA has an extremely rugged and reliable construction and an integrated DC link reactor up to 250 kW.

The converter system is fit for digitalization. Thanks to its full integration in the SINAMICS CONNECT 300 system, data from up to eight converters can be acquired and transferred to the MindSphere cloud solution. The MindSphere application "Analyze MyDrives" facilitates the evaluation of data – tailored to individual customer needs. This simplifies the acquisition and evaluation of converter conditions.

Further, the SINAMICS G120XA converter series provides innovative hardware and software functions, e.g. for controlling synchronous reluctance drive systems with SIMOTICS reluctance motors. In this way, the SINAMICS G120XA converter series makes a substantial contribution towards saving energy and makes more careful use of our natural resources.

Portfolio range

The SINAMICS G120XA, USS and PN versions, converter series offers a seamless system approach with wide options of built-in communication interfaces including PROFINET, EtherNet/IP or USS, Modbus RTU, BACnet MS/TP.
