Why do I get a "The description file for 'AX8108-0110-0105' can not be found." in my TwinCAT Drive Manager 2 project?

I have a TwinCAT Drive Manager 2 project with several axis and it worked for some time. However, now when I open the project and select a terminal or a drive I get the following error in the drive manager project:

No description file

  • See TwinCAT Drive Manager 2 output window for more details

drive manager 2 project error

When I check the output window I see the following

How can I get my TwinCAT Drive Manager 2 project to work again?

Solution

  • I found an easier way to fix it - in TwinCAT 3, at the top bar, choose TwinCAT. Then click on EtherCAT devices --> update device Description. Run the process only once. then activate configuration or close TwinCAT and reopen it.
