    After I turned on power, the machine didn't work even control console screen show the "protect guards" were normal. The main drive does not open the manual brake. I can clear all the errors on the console screen but the machine does not work. Have any of you had such an error? Please help me fix this error.

    is there any other error message? and what is the UWR status? It would be easy to understand if you upload the UWR slot 9 picture

    The picture is saying that all guards are closed but main drive stop because guards are open. So check all safety relay boards.
