Hello!
I picked up an MV40 with a Fanuc 6M-B control late last year that had some problems and wouldn't turn on. After tracking that down to a shorted limit switch on the ATC, the machine had a memory error, certainly caused by my efforts finding that short. The parameters were lost, I couldn't get a backup, and the only manual I have has a parameter table for an MV50 for some reason which I tried using. I then borrowed the parameters from another user here and the machine is finally up and running, but I am still having trouble with the ATC (the lender's machine had their ATC removed, so it may be a parameter issue.) There's evidence of some wiring repair above the carousel, though I don't have a diagram to reference and see if it's correct. I can cycle through the tool change steps with the M8x and 9x commands, but whenever the carousel needs to rotate to another position, it just spins endlessly.
I'm not sure where to get a manual with more in depth service information or wiring diagrams. I tried contacting Mori with no success.
Any help with this issue would be greatly appreciated, thank you!
Also, while cycling the ATC manually, I noticed that the spindle isn't at the correct height. The manual I have isn't clear about how to adjust the height for a tool change. Can anyone explain that to me?
