Microstepping Drive

EDM-453 - Microstepping Drive


The EDM-453 microstepping drive provides substantial benefits for increased system resolution, low noise and smooth motion. The power stage is designed to suit low electrical time constant motors and achieve high dynamic performance.

Motor Highlights

  • Resolution switch from 1/2 up to 1/64 microsteps

  • High angular resolution in static and dynamic

  • Smooth operation, low noise

  • Boost mode for higher torque / acceleration output

  • Stand-by mode for optimized heat management

  • Chopper control mode selectable between regenerative and freewheeling

  • Clock frequency up to 150 kHz

  • All inputs opto-isolated

  • Short circuit and overtemperature protection

Customization Available

  • Please contact us for more information on the EDM-453 or custom drive solutions.
