I have recently been getting this error "TR_HWERR, CPU Fail Error [Fail Safe] !" Sometimes the machine start comes back on & sometimes I have to let it sit for a while. After getting this error this morning I shut everything down & rebooted the controller & computer. That worked but now I am getting a "TR_FG16e,Overspeed Error". As of right now I can only run thr CMM on 10% speed.
