Running an NC/Conversational program, while rapiding, feeding, milling, drilling, tapping, etc. It doesn't seem to matter what the machine is doing when it happens. Thanks for that info! No, for whatever reason the power supply has not been changed - though it's probably where I might start, if it were me. The thing with re-wiring the backplane with soldered joints is purely a precautionary one - for mostly intermittent faults, it's a good idea and quickly done. The most common one being to the unclamp button on the head cover. See if you can tell when it happens as there are only a few things that use 24v from the supply.īad relays or the diodes in the relay bases (they are in the little LED block in the relay base).Ī pinched cable. It may be that you have something else that is breaking down and causing the 24v to dip and will cause this. The 24v supply is what will give that error if it blips sufficiently low. Was the power supply changed? There is no other source of 24v in that cabinet. I just thought I'd bounce this off the community to see what other ideas are out there for what's going on.Īh, I've just noticed that it had a backplane changed. What's going on here? My manager promises we'll call Hurco or Brooks Associates in the morning. It happened twice more after that, once while manually touching off a tool (jogging Z-) and again while cutting a (very expensive and complex ) part. Almost exactly 2 hours later, the same thing happened, the machine was sitting idle and the error occurred. I powered down and restarted, and all was well again. I came back to the machine to find that the 'MEI XMP motion controller subsystem failure' message had returned. This morning, after calibrating and warming up the machine, and then completing a program, I was away from the machine for maybe 15 minutes while it sad idle.

I let my manager and boss know, and that's as far as that message went. I powered down and restarted, and all was well. The system was also reformatted, because the service technicians that worked the case felt like the software had gone corrupt after another error message was displayed (though I forget what exactly that message was).Ī few days after the work was done, during axis calibration, I got an error message reading 'MEI XMP motion controller subsystem failure' and the system shut down.

The board was replaced, as was the 'backing board' (the board that all of the other drive boards plug in to, basically the motherboard) and the cable that connects the two XMP boards to one-another. At work I run a Hurco VMX42, I'm not positive but I think the software build is 08.01.09.24.Ī few months ago the XMP board that controls XYZ axis went kaput and the following error message was displayed: 'No motion control boards were detected in the system'.
