Hi guys, I hope you're all doing well
Sorry for the OT but we have a problem with a Daewoo lathe and as always
this is the first place I think of.
So, this morning the lathe started up as always, but when we selected the
gear to validate the spindle movement the screen showed a 409 SERVO ALARM
and the spindle drive on the back was showing alarm number 12. From what I
could find on several forums this is an overload alarm and in the worst
case scenario the IGBT firing module or the IGBT module itself could be
damaged.
Is there any way to check this in an easy manner?
Also, is it possible to adapt a normal VFD in case this is the problem?
Because maybe there are some Fanuc Serial protocol to analog voltage
converters (I'm just wishing such an adapter exists) that could be used.
Thanks as always for your help!
Leonardo
Is there a schematic?
