Hi all.
I have a 1986 QT20N (Mazatrol CAM T2) with Fanuc model 12 (A06B-6044-H212) spindle drive.
Machine is working well for about 10-15 minutes but after that Alarm 20 NMI emergency stop and alarm 204 spindle controller malfunction is turning on.
So i have to wait for about 40-50 minutes to be able to work again about 10-15 minutes.
Is like some component is heating and i have to wait to cool down.
Any idea about this malfunction?
Or, Can somebody advise me about a AC spindle drive upgrade? Or a VFD sensor less much newer that is compatible with my machine?
I would really hate to start a so called retrofit with Chinese controller, motors and drives and give up Mazatrol.
