Hi Guys.

I have a problem with my YAM MV 3 A with Fanuc 0M.

Out of the blue after i started it up the other day, the tool magazine just keeps rotating, when i call a tool. No alarms No nothing.

All the sensors in the magazine lights up,when the tool pocket passes them but i seems like the controller dosen´t get the signal?

Anybody that had this error before or somthing like this?


I can execute a M6 if i don´t call a tool, an i just grabs and changes the one that is in position, but as soon as i call a random tool from the magazine, it just keeps rotation... can´t stop it, only emegency stop can make it stop.


Hope i guys have som good ideas, to what the problem is.


Kind regards Martin
