EtherCAT Devices Backup

This function replicates the network topology and the AKD, AKD PDMM, AKD-C, AKD-N, and AKD2G drive's unique ID, firmware, and data.

To accomplish the backup, a copy of the firmware package is required.

Different scenarios are possible when clicking this button:

Scenario 1 - Archived Firmware Copy = Firmware used on Drives

  • If an archived copy of the same firmware package is on the controller as is used on the drives, clicking the button starts the backup.
    • If a copy of the firmware package cannot be found, you are prompted to browse for one or more.
  • A link to the Kollmorgen website is provided; all firmware packages are on the site.

Scenario 2 - Archived Firmware Copy Not = Network Configuration

  • If an archive is found on the controller, but it does not match the network configuration, you are prompted to browse for one or download one from the website.
  • This message appears if the EtherCAT network topology discovered during backup does not match the topology expected by the KAS application:
    • The message shows the number of discovered devices, the number that were expected, and how many are disconnected.

Scenario 3 - Only Unique ID Backed Up

  • For all other EtherCAT devices (e.g., couplers, IOs, ServoStar drives, and third-party devices), only the unique ID is backed up.


  • The firmware package files on the Kollmorgen website are saved in a .ZIP format.
    You must unzip the download to access the .TGZ file .
