AKD EtherCAT | 3 Installation and Setup
3.6 Setting up Ethernet over EtherCAT (EoE)
If you are using firmware version 1.16 or later and your EtherCAT master supports Ethernet
over EtherCAT (EoE), a WorkBench connection to your drive can be established without con-
necting to the drive’s service port.
If the service port and EoE network interface are used in parallel, the service port network
interface shall be configured to be in a different subnet than the EoE network interface. Run-
ning both network interface in the same subnet is NOT supported.
The master will use the EtherCAT mailbox to forward the Ethernet traffic from your PC to the
drive, allowing you to access the drive as if it was connected over Ethernet.
The following walk through uses a TwinCAT master as an example.
3.6.1 EtherCAT Device Settings
The first step is to make sure your EtherCAT device has EoE enabled. TwinCAT has a ded-
icated “EoE Support” page inside the EtherCAT device’s settings.
Enable "Virtual Ethernet Switch." Check the box "Connect to TCP/IP Stack."
3.6.2 Drive Settings
After setting up the EtherCAT device, you must enable EoE for the drive. In TwinCAT there
is an EoE page within the Drive’s Mailbox settings. If the EoE page is not displayed, add the
drive to the EtherCAT network again, using the latest device description.
