Siemens has announced a new enclosed drive system, the Sinamics G120XE, which is designed for industrial pump, fan and compressor applications in a variety of markets. Built around the Sinamics G120X infrastructure drive, Siemens says this new enclosed system is ideal for design and commissioning in industries such as oil and gas/petrochemical, water/wastewater, power plants, industrial climate control, refrigeration and industrial chillers.

A NEMA 1 enclosure is standard to the system, with a NEMA 12 version also available, featuring appropriate ventilation and air filters. Siemens says the base enclosure is suitable for wall mounting to 75 hp applications, while the free-standing floor module is capable of 200 hp.

Standard electrical characteristics of the drive system include a UL508A listing, short circuit current rating (SCCR) to 65kA, circuit breaker disconnect with flange-mounted operator handle and mechanical door interlock. It also includes a control power transformer for internal power control and a power module with pulse width modulation (PWM) insulated-gate bipolar transistor (IGBT) inverter. Overload ratings enable operation in either light- or high-overload duty conditions.

The enclosure ventilation fans on the Sinamics G120XE are controlled via a relay and run only as needed, which Siemens says results in significant energy saving and noise reduction. Optional features on the enclosure include output filters and reduced voltage soft start (RVSS) bypass.   

A key feature of the G120XE is the intelligent operator panel, IOP-2. In addition to the door-mounted IOP-2 keypad and display, the drive can also be commissioned, setup or modified using a laptop, tablet or smartphone by installing the Smart Access Module. Another option for commissioning, setup or drive modification is to use the Siemens Totally Integrated Automation (TIA) portal via a GSD file. 

Sinamics G120XE is ready for digitalization and remote monitoring with a built-in web-server and the ability to connect to the Sinamics Connect 300, reportedly enabling operators and maintenance personnel to access real-time status and cloud-based analytics from anywhere using the Analyze MyDrive app.
