Indexer Overview


The indexer, or controller, provides step and direction outputs to the driver. Most applications require that the indexer manage other control functions as well, including acceleration, deceleration, steps per second and distance. The indexer can also interface to and control many other external signals.


Microprocessor based indexers offer a great deal of flexibility in that they can operate in either stand-alone mode or interfaced to a host computer.
