Title: Fanuc problems.
Post by: Sam on March 12, 2008, 02:35:28 AM

Thought I might be able to get some advise on troubleshooting a machining center thats just been sitting idle in the shop for 4 years. I have seen it run previously, and if memory serves correct, the travel limit was possibly exceeded, and the error began at that time. The error that is displayed states "Y pulsecoder disconnect". Nothing has been physically disconnected. What would give this error other than disconnecting the cable? I have not taken anything apart on the motor yet to inspect it. If the machine had hard-stopped, would a power surge cause something to go bad, and result in this error? Maybe the limit switches were not functioning, I don't know, nor do I know that the limits were in fact exceeded. The magnascale also indicates a problem with an error LED, but on the X axis. Any advise on troubleshooting this is greatly appreciated.

Hi Sam, Just wondering if you got your Fanuc problem solved. I have the same problem on a machine with Fanuc 6M.

John.
