Functional Safety Network with Safety Drive System

Overview

Description

This industrial motor drive and network system supports functional safety. Powered by two independent 32-bit RX72N MCUs, it ensures control and emergency power cutoff in hazardous conditions. Each MCU independently verifies inputs for actions like PLC emergency stops to ensure motor safety. The two MCUs run the same process and check each other through a cross-monitoring interface.

System Benefits:

  • Renesas supports the software required for functional safety control blocks to reduce customers' development and certification time and costs
  • Simplified application development by separating functional safety control blocks from general blocks (network devices or motor control devices)
  • Select the optimal MCU for your functional safety system from Renesas' broad RX family portfolio
