AC Servo

The Renesas' AC servo system integrates motor control with EtherCAT design to support high-speed and high-precision motor control through synchronizing time-sensitive industrial Ethernet communications. The system consists of three blocks: system control, power drive, and motor encoder, which are physically isolated while maintaining a high degree of interconnectivity. Utilizing a high-performance MPU, this monolithic design outperforms traditional two-chip platforms in performance and cost.

System Benefits:

• Easily implement motor control using the CiA 402 drive profile via EtherCAT, with guidance from the system board.
• 2-in-1 chip design eliminates the need for an additional FPGA, optimizing overall system cost.
• Renesas supplies over 50% of the system's BOM, reducing delivery concerns associated with sourcing from multiple vendors.
