Cyclone Fanuc 0T alarm 2006; Spindle failed to reach speed

[stevenl]

Suddenly got this problem randomly when a program is running. The spindle is running fine and at set speed. This alarm come and go often.
But i tried to give the control box module a knock and it seems to work. Maybe something is loose in the control panel that effects this? Cant think of anything though.

But another thing, it seems to be better when the spindle have run some time, over 10 minues maybe.

Any suggestions?
