Closed loop stepper

Block diagram

Overview

Our integrated circuits and reference designs help you create compact, robust and efficient closed loop stepper motor drives with high-resolution positioning, accurate torque and smooth motion from zero to high speed. Multiprotocol industrial interfaces ensure easy control through the PLC or industrial PC.

Design requirements

Closed loop stepper drive systems often require:

  • Small form factor, efficient and protected power stage with fault feedback.
  • Advanced digital processing for smooth and accurate closed-loop control.
  • Accurate angle and current feedback sense for high-resolution micro-stepping.
  • Robust, low latency industrial interfaces with high EMC immunity.
