I'm having trouble with the axis drives on a V2XT. I don't have any good info on it, just the basic prints and manual.
History on the machine before I was called in:
-bought through a Gov. Auction
-All the cables between the machine and cabinet were cut
(motors, encoders, limits, etc)
-wires were repaced with "factory" wires
Since I was on it:
-rewired machine for correct voltage of supply
-recheck all wires vs. print
- checked all voltages in machine
-checked all limits/switches to panel
-went through the trouble shooting for replaced axis wires (found out some motors, encoders, tachs were wired backwards from the factory)
--I have all axis disconnected except Z, the first to home. figured I'd try to get one axis at a time--
What it's doing now:
-when I first enable drives the Z will stay still
-The hand pot will work in "jog off limits"
-the jog switch will work the correct direction, BUT when you release the switch the drive will not stop
-Try to home and it will go past the home limit to the overtravel, then stop with a overtravel alarm
-After overtravel alarm is reset and drives enabled again the axis will run away.
I then again went through all the wires that were replaced before ME, and then the rest of the cabinet incase something was hit in the process of replacing the wires.
I have enough time in this it has to be something stupid! (nuts)
Any ideas would be helpful.
Sorry for any misspelling, or sutch. I work third shift, a Haas and a Motch gave me troubles all night. Then I went to bang my head on this some more.
Thanks in advance
