Abstract :
State of the art drives have greatly increased features and capabilities due to being software based (microprocessor controlled). Examples of this are capability and interfacing to hierarchy devices such as programmable controllers, instrument distributed systems, and other microprocessor-based equipment capable of performing many functions other than just controlling drive speeds. These functions can be programmable controller-type functions, process maintenance, diagnostics, etc. The need for functional descriptions is discussed, an outline of a typical functional description is given, and suggestions to permit optimization of the drive system are presented.<>
