RX72M Group
Single-Chip Motor Control via EtherCAT Communications
Outline
This application note describes a sample program for the RX72M. The program has an encoder vector
control function for a permanent magnet synchronous motor (hereinafter referred to as a PMSM) and works
with the EtherCAT communications controller of the RX72M. The module provides an interface via the
EtherCAT Slave Stack Code (SSC) of Beckhoff, which is used in the RX family products that incorporate an
EtherCAT slave controller (ESC) for industrial Ethernet communications.
The FIT module itself does not include the SSC. Therefore, generate the executable code after obtaining the
sample SSC from the EtherCAT Technology Group (ETG Association).
This FIT module is hereinafter referred to as the EtherCAT FIT module.
Target Devices
RX72M group devices
When applying the sample program covered in this application note to another microcomputer, modify the
program according to the specifications for the target microcomputer and conduct an extensive evaluation
and testing of the modified program.
