    Hello,

    I have an application with two slaves drives (Ethercat Beckhoff EL7041) synchronized via MC_CamIn to a virtual master drive running in Time_Position_Profile.

    I'm making some test under Codesys Control Win (not RTE for the moment).

    The problem is that when the master as finished his position profile (stopped at his final position) , the slaves are still running slowly to their final position, like they were in late, not perfectly synchronized.

    Should it be a problem due to Control Win instead of RTE, or some settings into the regulation loop ?

    Thanks in advance.

    Cedric

    Hi,
    hm...hard to say,
    how do you use th drive, there is no SoftMotion driver available.

    What about moven by simple MC_MoveAbs.. does this work?

    Hi,

    I'm using the drives as in the PosControl example project, sending velocity to the drives and actual positions as feedback.

    I'm going to try a simple MC_MoveAbsolute command I see how does it work, I'll tell you.

    Thanks
