With power range from 1–700 hp (0.75–630 kW), Sinamics G120X is optimized for pump, fan and compressor applications

Siemens is introducing the new Sinamics G120X drive, a simple, seamless and easy-to-use drive, designed for use in pump, fan and compressor applications in industries such as water/wastewater, HVAC/R, irrigation/agriculture and in industrial environments. Sinamics G120X has a power range of 1–700 hp (0.75–630 kW) and can operate in a temperature range from -4 to +140° F (-20 to +60° C) with any standard motor, including synchronous reluctance motors (SRM).  It has an integral DC choke which improves harmonics and EMC performance. Sinamics G120X meets all the latest and upcoming UL, NEMA and EN/IEC standards for 2019 and beyond and offers up to 100 kA short-circuit current rating (SCCR) ensuring enhanced product safety and energy efficiency.

Sinamics G120X easily integrates into existing applications and is configured for cost-optimization and resource-saving operation, which ultimately helps reduce total cost of ownership.  

The compact design of the G120X saves space in the control cabinet and can also be easily integrated in to MCC solutions (including plug-in buckets).  Even without an additional output reactor, Sinamics G120X drives enable motor cable lengths of up to 492 ft. (150 m) with category C2 or C3 filter and up to 1476 ft. (450 m) without filter and have hardware-based SIL3-certified safety functions built-in.

“The Sinamics G120X offers outstanding “out-of-the-box” ease of use and is simple to commission and operate using its high-resolution graphical color keypad, known as IOP-2 (intelligent operator panel), as well as the optional Wi-Fi-enabled Smart Access wireless module — both optimized for pump and fan applications”, states Nikunj Shah, product manager, Siemens, Digital Factory, US. 

Shah continues, “Sinamics G120X-series drives offer an automatic restart function after power failures.  The multi-pump/staging operation mode allows the user to control several pumps using just one drive. Integrated functions like pipe filling mode, soft start, deragging and anti-cavitation help users reduce system maintenance, save repair costs and extend the life of other equipment in the system.  An energy-savings mode automatically switches the motor on and off to save energy and reduce wear.”  

It has Class 3C3 coating, which is suitable for harsh environments where corrosive gases such as hydrogen sulfide (H2S), chlorine (Cl) or ammonia (NH3) are often present.  A high C2 or C1 EMC category ensures the drive can be reliably used in any kind of industrial and public network. 

Sinamics G120X is compliant with all relevant EU and upcoming NEMA energy-saving standards and offers an operating efficiency level of over 98% (efficiency class IE2).  Its comprehensive range of integrated application-specific functions for pumps and fans ensures improved energy efficiency through the use of eco mode to automatically change the output voltage either up or down slightly to find a minimum input power or implementing efficiency optimization to change motor flux to optimize system performance and minimize energy losses.

Users in water and wastewater — both municipal and C&I — have multiple communication platform requirements.  Sinamics G120X meets this challenge with communications options such as PROFINET, EtherNet/IP, PROFIBUS DP, USS, Modbus RTU, and BACnet MS/TP. 

Sinamics G120X is also fit for digitalization because it can be linked to Mindsphere by using Sinamics Connect 300 and the Mindsphere app Analyze MyDrives.
