Hello,
I am stumped. We have a 1997 VF-1 that locks up on warm days. In the afternoon on a warm day the machine will be in the middle of running a program and everything locks up, the spindle is running, the CRT appears normal but the machine is not moving, X,Y or Z. The key pad dose not beep nor do any keys do anything.
We have to turn off the power, I think the normal power off, let the fan cool off the boards in the back, power up and run like nothing happened.
In the mean time last year the the processor board went bad and I replaced it, upgraded the software. Shortly after we lost the Spindle Drive unit, replaced it, no problems.
But on hot days it still locks up. Haas swaped video boards for me, same deal,
I replaced the Mocon board, same deal.
I replaced the power supply, same deal.
I replaced the low power board, same thing, there is a temp sensor on that board, just a hunch.
We also replaced the Video board, same deal.
I had a spare key pad ribbon cable, hooked it up, no help.
I also replaced the low power transformer, no help.
Yes, I tried running it with the work light off.
I have not messed with it for a few months, we run it with a fan and the e-cabinet open, it runs every day but now that it is warming up it is on my table again.
All the fans are running and the machine runs real good. Our input power is at 208 V and I have six other Haas VF machines that have never done this.
Next I am thinking of the I.O. board, I have had those go bad in other Haas machines we have but I do not think it would lock thing up like that.
I did have the guy from M.T.S. spend a day with it last year, He tried a few things, no help.
This forum is really cool, the common thread seem to be that o.e.ms are not a lot of help with this stuff, it is fun to see the industry returning to it's roots,
"running it means you know how to fix it".
Have a nice day!
