I am a new student learning CNC programming/machining. I am working with a Mori-Seiki SL-0 with the Yasnac LX1 controller. When I first powered it up, everything worked fine with no alarm codes. But the past two or three times I turn it on, it displays a Alarm Code 332 (Fuse Blown Z) and also Alarm Code 280 (Machine Unready). I called Yasnac and they told me to remove the servo board to see if the fuse LED is on (which it is). I then left the board unplugged and untouched for about a week. Then I came back and plugged it back it back in and the machine worked again with no alarm codes. But now when I turn the machine on, I get the same two alarm codes (332 and 280).
The voltage I am running the machine at is from 208v~214v. It has two buck type step down transformers.
Anybody have any idea what is going on?
Thank you for any help that you can provide.
