EtherCat Communication Problem_MPB20/21

[Vasilis]

Hi all, i build my machines with two Rexroth drives( MPB20/21 and MPE20) via Ethercat SOE . I have a strange problem and it seems that the the Drive MPB20/21 lost the communication for some ms or this is what i think . At the video https://www.youtube.com/shorts/g7PCFLUaDUI you can see that the Values (position feedback and some others) that are inputs to my plc from the drive are going to 0 and after take values again .I have to noticed that at the second drive MPE20 all this values are Stable all the time .  I appreciate any help because its very important to solve this issue.

What control system are you using? Did you have a look to the control system monitoring. Usually it shows if some telegrams were not received in time on a special monitoring screen e.g. at a Beckhoff control. Vice versa maybe send as well the drive parameter file (in format "all parameters"). There you should see if a communication problem F4... error is present.

I am using Beckoff coupler card for Ethercat with Beijer Plc and at codesys monitoring i don't have any lost packets at the communication. Also as you can see at the previous video this 0's are only for some ms after that it take values again but the values are not stable as the second drive , plays all the time.The mystery is that the second drive that is Economy series Mpe20 and it is after the Mpb20 doesn't have any problem. I appreciate any idea.
