My R2E3 is suddenly "randomly" popping axis limits when it is no where near the limit switches. I say random because it was popping the error at exactly the same spot in a particular program the other day but again, no where near the limits. The program would run fine up until this point and then kick out the axis drives...after re-homing the machine and restarting the program where it left off, the program would finish with no problem.
Today I started the machine up and went to home the axis and the machine popped an axis limit almost immediately, again, no where near the limit switches. After re-enabling the drives and homing, I started running a program...different program than the one that was giving me problems before. I ran the program about halfway through and again it popped the limit.
My maintainance manual says to check the voltage to the FMDC board...this checks out fine. After this, it says to check the FIST monitor. Unfortunately, the manual is less than vague about connecting a computer to the FMDC board...
Any ideas on why it would be causing the limit error or help on how to connect a PC to check the FIST monitor would be great.
Thanks,
Ryan
