Siemens Sinamics G120X drives suited for pump, fan, compressor duty

Siemens describes its new Sinamics G120X drive as simple, seamless and easy-to-use, designed for use in pump, fan and compressor applications in industries such as water/wastewater, HVAC/R and industrial environments.

Sinamics G120X power range is 1-700 hp (0.75-630 kW) and it can operate in temperatures from -4 to +140° F (-20 to +60° C) with any standard motor, including synchronous reluctance motors (SRM). An integral DC choke 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 shortcircuit current rating (SCCR) ensuring enhanced product safety and energy efficiency. The company says the drive easily integrates into existing applications and is configured for cost-optimization and resource-saving operation to help to reduce the total cost of ownership.

Compact design saves control-cabinet space and allows easy integration into 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 filters and up to 1,476 ft (450 m) without a filter; hardwarebased SIL3-certified safety functions are built in.

The Sinamics G120X is simple to commission and operate using its high-resolution graphical color keypad (aka IOP-2 — intelligent operator panel), as well as the optional Wi-Fienabled Smart Access wireless module; both are optimized for pump and fan applications.

The drives offer automatic restart after power failures and the multi-pump/staging operation mode allows the user to control several pumps using one drive. An energy-saving mode automatically switches the motor on and off to save energy and reduce wear. Built-in functions display energy consumption and savings.

The G120X’s Class 3C3 coating is suitable for harsh environments where corrosive gases such as hydrogen sulphide (H2S) are present. A high C2 or C1 EMC category ensures the drive can be reliably used in any kind of industrial and public networks. It offers an operating efficiency level of over 98% (efficiency class IE2).

Sinamics G120X is fit for digitalization and can be linked to Mindsphere by using Sinamics Connect 300 and the Mindsphere app Analyze MyDrives which enable the visualization and analysis of status information for process optimization and maintenance strategies.
