Though manufactured and marketed as a commodity with widespread industry acceptance, ASDs do not always prove as reliable for particular applications as buyers and sellers might first believe. Considered separately, both ASDs and motors are inherently reliable. Problems typically occur, however, when the two are integrated into an application-specific system. Many of these system problems, in turn, are initially due to specifying and purchasing practices, and then to improper installation and implementation. ASD/low-voltage motor systems are used extensively by manufacturing and many other industries for a variety of reasons, including flexibility in manufacturing, energy conservation, and improved process control. There can be, however, reliability problems with ASD/motor systems. This report discusses ASD/motor system-related issues and provides guidance in identifying and solving the root causes of problems.
