Maxon EtherCAT SDK

Overview

This is a C++ library providing a high-level interface for controlling Maxon motor drivers of the EPOS line over EtherCAT (using the CANopen over EtherCAT CoE protocol). It is modified by Linghao Zhang based on elmo_ethercat_sdk by Jonas Junger.

The lower level EtherCAT communication is handled by the soem_interface library.

The maxon_epos_ethercat_sdk is developed on Ubuntu 20.04 LTS with ROS Noetic.

The source code is released under the BSD-3-Clause license. A copy of the license is available in the LICENSE file.
