Fanuc AC spindle Alarm AL-12


Our VMC gives spindle alarm 1008 on display. Spindle units led display shows AL-12(Excessive current on DC-link). Alarm comes when spindle stop command is issued(M05). Spindle accelerates and runs fine but every M05 gives this alarm. Machine is Kitamura Mycenter 2X from 1995 with Fanuc 0MC. Anyone had this trouble here? If yes how it was solved?
