EtherCAT Devices Backup / Restore Limitations

  • Only AKD and AKD2G drives are supported for backup/restore.
    • Kollmorgen S300 and S700 drives are not supported by backup/restore.
  • AKD PDMM or PCMM system backup or restore is a two-step process:
    1. Backup or Restore the controller.
    2. Backup or Restore the drives (including the AKD drive inside the AKD PDMM).
  • Only a single backup is supported in the controller at one time.

    • To keep multiple backup configurations, perform the backup and then export it to a local PC.
      When ready to restore, import the specific backup file to the controller and then perform the restore.


    • An import overwrites any backup existing in the controller's removable storage device.

Backup Conditions

These conditions must be met before starting an EtherCAT device backup:

  1. The KAS application should be run and then stopped.
  2. Do not power cycle or reboot the controller after stopping the KAS application.

The EtherCAT Devices Backup and EtherCAT Devices Restore functions are not permitted:

  • While a PLC application is running.
  • When the KAS-IDE is in Online Configuration Mode.
    • Stop the PLC application or disable Online Configuration Mode before a Backup or Restore.

All drives on the EtherCAT network must have the same firmware version.

  • The AKD firmware version must be 01-06-00-003 or higher.
  • AKD and AKD2G firmware packages are available for all production releases.
