DESCRIPTION

The GS-D500A is a member of the SGS-THOMSON 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 unusually 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 conduction and commutation losses for increased efficiency; this, combined with a complete protection scheme, results in an extremely rugged unit suitable for harsh environment operation.
