You should capture the packets on the network interface with WireShark. This will give you a much better understanding of what issues there are.
Hello, I'm working with a FAULHABER and BECKHOFF setup. I managed to be able to integrate both systems and I can control the motor in different operation modes. However my goal is to be able to control the velocity of the motor based on the analog input from an external potentiometer that I attached to my AI PLC module (EL3104). The moment I try to control the velocity based on it, the motor shuts down immediately. I'll attatch the code, as well as the log from the Motion Manager from Faulhaber, which gives some precise error codes. Also I'm adding the terminal output.
Code: test.zip
Terminal output: test.txt
Communication log from Faulhaber Motion Manager: Communication.csv
I'm struggling because I can only see a voltage issue, however no limit is being reached because the physical setup doesn't allow it, and also because it doesn't pop up when simply running the motor by commanding different velocities manually one by one. So my guess is that the issue is simply a representation of the immediate shutdown. If so, then I don't know why it shuts down. So I'm a bit lost.
