GS-D500A
100V/5A STEP AND MICROSTEP DRIVE BOARD FOR STEPPER MOTORS
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 consumption 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
DESCRIP TION 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 m icros tep mode. On top of that if offers an unusually large number o f 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.
