Mori Seiki nh5000 stops after pallet B does a 180 degree rotation - without alarm

Hey,

In before thanks to anyone who puts his time in this.

I have a kinda weird problem. On Mori Seiki nh5000.Mid work mori just stopped working after pallet B did a 180 degree rotation.Working time goes on but nothing moves ( no alarms).
If i block pallet B(with program that does nothing) and just work with pallet A everythingˇs fine.I checked program and everything its like it was before (when it was still fine).
Checked all the sensors under the table, clamp, unclamp, arm down, arm up (both pallets are using the same sensors) and it looks ok.
Pallet sits fine and in mdi mode i manage to run it thru the whole cyclus just fine.The problem starts in automatic mode when pallet B does a 180 degree rotation.

Thanks in advance.

I am going on a limb here and say you have a Fanuc CNC on this machine. Check SYSTEM Diagnostic and see if any of the bits are set to 1 when you are in this state.

If it works in MDI, there is something in your program causing it.

You should be able to contact DMG MORI directly. They have some great techs available for phone service. They are now direct. You can get the number from the website DMG MORI USA ? Machine Tools, CNC Milling Machines, Lathes and Turning Centers

Unsure if you found the problem or not but my machine is doing the exact same thing as of today. Was on the phone with mori and they seem to think that something is worn towards the zero point.

try to use the rotation with feed 2000 , M10 G01 B? F2000 M11 .
PERHAPS THE PALLET IS TOO HEAVY
