[peterklos]

We have a leadwell MCV with Fanuc Om controller , due to faulty tool offset the z Axis crashed into the bed , we managed to home after the crash but now no Axis will move .screen has no fault codes or alarms
have checked the obvious , eg Estop ok , Air pressure OK , Tried Can P on start up, checked limit switches
Any ideas ?? jobs are starting to pile up and we have run out of solutions

Here is where I would start.

I am not familiar with the diagnostic function of the fanuc.
How do I display the PMCDGN data as indicated on the pdf

You press the same button that takes you to the parameters, you press that button several times and it will toggle to parameters then Diagnostic(which is PMCDGN) , and Ladder (if the bit is set to display the ladder)
