Siemens, a supplier of systems for power generation and transmission as well as medical diagnosis, introduces its Sinamics G120X drive, which is designed as an easy-to-use drive, meant for use in pump, fan, and compressor applications in industries such as water/wastewater, HVAC/R, irrigation/agriculture and in industrial environments.
Sinamics G120X is made to have a power range of 1–700 hp (0.75–630 kW) and should 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 is designed to improve harmonics and EMC performance. The company reports that Sinamics G120X meets the latest as well as upcoming UL, NEMA, and EN/IEC standards for 2019 and offers up to 100 kA short-circuit current rating (SCCR) which is meant to provide enhanced product safety and energy efficiency.
Sinamics G120X is designed to integrate into existing applications and be configured for cost-optimization and resource-saving operation, which would ultimately help reduce total cost of ownership.
The compact design of the G120X is supposed to save space in the control cabinet and be more easily integrated in to MCC systems (including plug-in buckets). Even without an additional output reactor, Sinamics G120X drives should be capable of enabling 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 can be operated 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.
“Sinamics G120X drives offer an automatic restart function after power failures and the multi-pump/staging operation mode allows the user to control several pumps using just one drive,” says Nikunj Shah, product manager, Siemens, Digital Factory, US. “Its energy-saving mode automatically switches the motor on and off to save energy and reduce wear. G120X also has built-in energy functions which display energy consumed as well as energy saved.”
The G120X has Class 3C3 coating which is designed to be suitable for harsh environments where the presence of corrosive gases such as Hydrogen Sulfide (H2S) is present. A high C2 or C1 EMC category is meant to ensure the drive can be reliably used in many kinds of industrial and public networks.
Sinamics G120X is compliant with relevant EU and upcoming NEMA energy-saving standards and should offer an operating efficiency level of over 98% (efficiency class IE2). Its range of integrated application-specific functions for pumps and fans is meant to improve energy efficiency through amount of actual energy needed in line with the actual load which should then provide best performance and minimal energy losses.
Sinamics G120X is also made for digitalization and to be linked to Mindsphere by using Sinamics Connect 300 and the Mindsphere app Analyze MyDrives. This is supposed to offer users the opportunity to analyze valuable operating data gathered from the drive and enable the visualization and analysis of status information, providing users with valuable data which can be used as the basis for process optimization and maintenance strategies. Mindsphere is the cloud-based, open IoT operating system from Siemens that connects products, plants, systems, and machines, while enabling a user to harness the wealth of data generated by IoT with advanced analytics.
