The concept of varying the speed of a motor, either manually or automatically. The desired operating speed (set speed) is relatively constant regardless of load.

a set of rules specifying a sequence of actions taken to solve a problem.

                                                        Ampere (amp) A unit used to define the rate of flow of electricity (current) in a circuit.

A device which draws power from a source other than the input signal and which produces as an output an enlarged reproduction of the essential features of its input.

An I/O module that contains circuits that convert analog dc input signals to digital values that can be manipulated by the processor. By implication, these analog inputs are usually direct (i.e., a data table value directly reflects the analog signal value).

any form of data transmission where the pneumatic, mechanical, or electrical energy signal is varied in direct proportion to the intensity of the physical quantity, property, or condition represented.

American National Standards Institute: The institute that co-ordinates the development of standards and guidelines used in the United States. ANSI is the only United States representative to the international Standards Organization.

Application Program Interface: The interface between the applications software and the application platform.

a structured set of protocols implementing the functions of the system.
Artificial intelligence The concept that computers can be programmed to assume capabilities such as learning, reasoning, adaptation and self-correction.
