Robot position feedback aggregator

Block diagram

Overview

Our integrated circuits and reference designs help you create a real-time robot position feedback aggregator gateway for safe, secure and reliable communication links to both the external motion controller and the position feedback encoders.

Design requirements

  • Flexibility to execute different industrial communication, encoder and proprietary protocols.
  • Support for different real-time protocol stacks.
  • To meet and exceed IEC 61800-3 EMC immunity.
  • Highly-efficient, sequenced and supervised voltage rails for reliable operation.
