One of the best integrated circuits (ICs) available in the market for developing an AC servo motor driver with EtherCAT communication is from the Xilinx Zynq UltraScale+ RFSoC family. The ZU7, ZU11, ZU17, and ZU19 chips are specifically designed for applications requiring high-speed data acquisition and processing as well as real-time control.
These ICs offer a combination of:
  • Dual-core ARM Cortex-A53 processors for application software.
  • Dual-core ARM Cortex-R5 processors for real-time control.
  • Up to 930k System Logic Cells.
  • Powerful DSP slices for math-intense operations.
The Zynq UltraScale+ RFSoCs can be used to implement EtherCAT communication using FPGA logic.
Before you finalize your choice, you should consider the power rating of your servo motor, the control speed required, and the complexity of your application. Each IC has different system logic cells, DSP slices, and I/O pin amounts, allowing for different levels of complexity and speed.
In summary
  • ZU7: This is the lowest throughout Zynq UltraScale+ RFSoC family and would suit lower complexity applications.
  • ZU11: This is a mid-range device in terms of system logic cells, DSP slices, and I/O pin amounts.
  • ZU17 and ZU19: These are the highest-end devices in this family and would be suited to more complex, larger-scale applications.
Please double-check the availability, cost, and packaging variants suiting your application needs before finalizing the IC. As you develop your schematic in Flux, we can continue to refine the details of your motor driver design including peripheral components.

Certainly, there are other series of microcontrollers suitable for developing an AC servo motor driver with EtherCAT realization. Here are a couple of more options:
  1. Beckoff's EL72x1-9014 series EtherCAT Servo Terminals: These are compact drives in the high-speed EtherCAT Terminal format with optimized digital current controller for the accurate control of AC servo motors. The integrated EtherCAT slave ensures fast communication. These terminals perfectly integrate into the entire Beckhoff system world.
  2. Infineon's XMC4800 series of microcontrollers: Infineon provides a range of XMC4800 microcontrollers which have an integrated EtherCAT node on an ARM Cortex-M4 processor. The XMC4800 devices are a powerful design option to bring EtherCAT capabilities to your servo motor applications. They also come with comprehensive development support, including low level drivers and example projects that can provide a good starting point for your design.
Please note that the selection of the perfect IC or series highly depends on your specific requirements in terms of power, control speed, temperature range, packaging, cost and availability.
