SGS Thomson Microelectronics GS-DC200SS, GS-DC200S, GS-DC200 Datasheet
GS-DC200 Family
STEPPER MOTOR CONTROL AND DRIVE SYSTEM FAMILY
DESCRIPTION
TheGS-DC200 seriesisafamilyofsingleEurocard
boards that contain allthe logicnecessary to operate a stepper motor, including the instructions decoding, the step timing generation, the storage of
the program to be executed. The motor interface
can deliver phase current up to 2.5A.
The boardscanbe used asa standalonecomplete
motion control system or they can be driven by a
central host computer.
TheGS-DC200family isbuilt around theGS-C200,
GS-C200S, GS-D200, GS-D200S modul es, (see
the relevant data sheet) and it retains all the features of these modules.
