Hello Guys, I have a Fanuc triple axis servo drive on one of my machines, and since last Thursday it has been randomly tripping out, and faulting the cnc control. It is from roughly 1995, and has been running just fine up until this point. Even while just sitting powered up, but with no servo motion commands it will trip out and shut off the machine. I noticed though, that when the cabinet doors are shut, it trips almost all the time, when I open the cabinet doors, it has been running since Friday, only tripping just once, early yesterday morning. The cabinet is air conditioned, and had the thermostat set at 95 degrees for the point to turn on. We turned it down, to 75 thinking that would help, but I think it actually made it worse. Would there be any way that on an old PCB, if something was going south on it, a humidity level that was too low could cause something to not work, and when it is hot and humid, it would function properly?
Here is a link to an identical PCB, http://www.fanucworld.com/media/image/800/0/A20B-1001-0770%20Front.jpg -- Thanks Rick Lair Superior Roll & Turning LLC 399 East Center Street Petersburg MI, 49270 PH: 734-279-1831 FAX: 734-279-1166 www.superiorroll.com ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
