hello and thank you in advance for any help/ suggestions you may be able to share with me on this topic.
this is regarding a Eurotech Elite twin spindle, twin turret lathe with a Fanuc 18iT control.
for some time now we have been getting this 401 servo alarm: x,z,y,b axis vrdy off only on head one at different times. it doesn't matter where it is during cut, part transfer, or if it is just idle. there have been times where it has ran for a solid week with no trouble then the following week, intermittent issues with this same alarm. also we don't always get the alarm on every axis like i have stated. sometimes it is only x and z axis.
so far our machine dealer won't even attempt to come out and take a look at it (it's out of warranty), Fanuc was out but only swapped out power supplies, i have done some troubleshooting with a Fanuc repair shop but with no luck.
