This controller takes a basic Model DC100A and adds an internally mounted length control card. It incorporates all the functions of the DC100A and a length controller, converting it to a stand-alone single axis controller. The length control card utilizes differential encoder inputs with x4 logic, providing 4000 counts of position resolution per motor revolution.All parameters can be programmed on the fly, and are installed through a serial communication link with one of Introl’s operator interfaces or a computer. As a stand-alone, this controller can be programmed with a single preset, executed each time the run input is initiated, or have one of four preset indexes selected externally.
