DESCRIPTION
The GS-D500A is a member of the SGS-THOM-
SON family of stepper motor driver modules and
boards. It drives motors in full step, half step and
microstep mode.
On top of that if offers an unusua lly large number
of features that allow a complete control of the
electromechanical characteristics of the motion
system to obtain optimum performance.
The powermos output stages offer both low con-
duction and commutation losses for increased effi-
ciency; this, combined with a complete protection
scheme, results in an extremely rugged unit suit-
able for harsh environment operation.
