Indexer Elements
|

Communication to the indexer is either Bus-based or through an RS-232/ RS-422 / USB serial port. In either case, the indexer is capable of receiving high level commands from a host computer and generating the necessary step and direction pulses to the driver.

The indexer includes an auxiliary I/O for monitoring inputs from external sources such as a Go, Jog, Home or Limit switch. It can also initiate other machine functions through the I/O output pins. |
