Hi
I have the similar alarm in my Mazak Mazatrol M2. When I switch on the power the following alarm appears on the screen.
"NMI 20 Emergency Stop"
When I press "reset" button, the alarm disappears for a moment and comes back again. When I press "reset" and "OT" button together, the hydraulic turns on and alarm disappears. But when i release these buttons, the alarm appears again. I checked all the "E stops" and they are fine. Can anyone has an idea please.
Thanks
Pcreek
