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 GS-D500A offers an unusually large number of features that allow a complete control of theelectromechanical characteristics of the motion systemto obtain optimumperformance.

The powermos output stages of GS-D500A 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.
