Subject: Why is there a five-cycle delay in motion?

     I briefly activated the motion and used an oscilloscope to record the data. The results clearly show a delay of five cycles in the feedback. This observation suggests a lag in response time during operation.

I've been collecting data on the Rexroth drive with an oscilloscope, and the results appear completely normal. However, I can't help but suspect that the use of the ctrlX X2 device might be causing issues. This problem has been bothering me for several days to the point of questioning everything. Could you please assist me? Thank you.

yzpguest Could you add some more information to your pictures, like which line is which signal?

Please also check out the post "Oscilloscope APP shows delay in signal tracking" as it is describing the same phenomenon.

Please beware that the ctrlX CORE X2 is a low power controller and will need higher cycle times or will not work for more complex motion calculation.
