GS-DC200 Family
STEPPER MOTOR CONTROL AND DRIVE SYSTEM FAMILY
DESCRIPTION
The GS-DC200 series is a family of single Eurocard
boards that contain all the logic necessary to oper-
ate a stepper motor, including the instructions de-
coding, the step timing generation, the storage of
the program to be executed. The motor interface
can deliver phase current up to 2.5A.
The boards can be used as a stand alone complete
motion control system or they can be driven by a
central host computer.
The GS-DC200 family is built around the GS-C200,
GS-C200S, GS-D200, GS-D200S modules, (see
the relevant data sheet) and it retains all the fea-
tures of these modules.
