    In many cases, bad connections or short circuits of motor power cable was the root cause. However you said it was okay, then replacement of main drive unit or motor itself might be the next step. Give it a try. Good luck!

    I would agree this sounds like a cable fault - have you done a continuity test on the cables to axis 1?

    @graemepaulin thnx for reply, Yes i did , everything looks fine. Now i wait till the fault occurs again so i re-do the continuity test in the position the robot stops in.
