WEG Electric Motors Corp.: Variable-Speed DriveAvailable for the CFW-11 variable-speed drive, the Pump Genius process control software manages and monitors up to six pumps in a coordinated system. It can operate motors from 5-150 hp in the 208- and 230/240-vac range and motors from 5-600 hp in the 480-vac range. The software is designed to reduce system operation and maintenance costs while increasing process accuracy and protection. The software provides control and protection as well as management of cycle hours and master and slave designation. It also monitors and controls system pressure or flow with available faults and alarms referencing low and high set points. The software monitors the operating hours of all the pumps in the system, adding and subtracting pumps as demand changes, all without the need for setting a cycle timer, which ensures equal pump run times without supervision, said the company. According to the manufacturer, the software offers the ability to have a floating master and slave rather than a system of fixed master and slave pumps. The CFW-11 VSD with Pump Genius software also monitors and alarms system, motor, and drive faults which alerts the operator to potential problems. The drives are available in various sizes, 2-600 hp, and include the company’s user-friendly graphic key pad HMI with its large character graphics and readout. The CFW-11 has a built-in dc link reactor, which helps mitigate the harmonic output on the ac line, and intelligent thermal management features that provide automatic cooling to the internal components of the drive.
