I have Simodrive 611 with fault 300201 axis x1 drive time out bus access, eror code 769. I have changed the power supply, bus cable, communication card of x1 bus, but every few days I have the same fault. I must reset to the machine to work. Any ideas?

Look for something external slowing or hanging the bus. We get a lot of this when one drive on the bus is slow to come up and the others time out waiting. everyone complains except the slowpoke.
