1 / 10 page GS-D500A 100V/5A STEP AND MICROSTEP DRIVE BOARD FOR STEPPER MOTORS June 1994 1/10 FEATURES 100V Operating Supply Voltage 5A/phase peak current 5, 25, 125 microsteps/step Full step and half step operation User selectable phase current 90 ° out of phase chopping to save power con- sumption Galvanic isolation Full output protection against short-circuits Thermal and undervoltage protection Step clock in excess of 200kHz Fault indication output Special circuit to reduce midrange instability 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. ABSOLUTE MAXIMUM RATINGS Symbol Parameter Value Unit Vs DC Supply Voltage 110 V Vss DC Logic Supply Voltage 13 V lph Output Current per Bridge 6Apk li Logic Input Current 30 mA Vis Isolation Voltage 500 V Tstg Storage Temperature Range – 20 to +85 °C Thop Operating Heatsink Temperature +85 °C Note: Absolute maximum ratings are limit values above which the unit can be permanently damaged * Thermal protection intervention @ Th > 90 °C |
