I've been working on a R-2000iC/125L with pretty standard software package (handling tool/DCS).
There's a taught position with PR as tool offset to slightly adjust this taught position.
And this robot was running for almost a week without program, been through that taught position thousands time.
But one day, robot just went to middle of nowhere and hit axis limit and I found that PR was changed from Cartesian to joint format, and also the numbers in PR were completely different then before.
And I'm positive that I'm the only person who can change coordination via teach pendant, and there's no such command like PR=JPOS in my program.
Just want to ask, is there any setup/routine/ that could overwrite numbers and coordination in position register?
