Lichuan LC10E Ethercat Absolute - 10mm following error

Hello,
I am working on a CNC mill with 4x Lichuan LC10E 23 bit absolute 1000W Servos. Setting up worked quite well following the tutorials and using the Marco Reps EL8 config and working from that. The machine is running and even the gantry is working. Now I am trying to tune the servos which turns out to be troublesome. After trying to get the following error down for a few hours I am left with a rather big F-Error during moves. The Error is scaling with speed. With 10000mm/ min I can't get it below a Value of 4.5mm. With 5000mm / min I can't get it below 2.25mm and so on. I tried changing almost every setting on the drive but can't get the F-Error any lower. So my last guess is that there is something wrong with the Ethercat timings or configs. Is it possible that this is a delay in ethercat between sending the position command and receiving the position feedback? Any help is appreciated
Best regards
Alex
