Help with alarms ("401 x axis servo vrdy signal off and 701 fan motor overheat)
Hello,
I run a Tsugami bx12 with a Fanuc LE1 control. Its pretty old, from 1994 i think so I know older machines are usually quirky.
The shop turned off the air yesterday at lunch and all the machines alarmed out with the "low air pressure" alarm. you have to turn off the machine to clear the alarm. So I turned it off and back on.
When I turned it back on it booted with the alarm "401:x axis servo vrdy signal off" (or something pretty close to that) on all my axises (x1 z1 c1 y1 b1 x2 z2) Ive gotten this alarm in the past and the only way ive found to clear it is turn off the breaker, wait somewhere between 30 mins and overnight then turn it back on and it is magically ok.
so that happened yesterday. I turned it on today and as I expected the 401 alarm was gone, however the "701: fan motor overheat" alarm was up. do I have a bad temp sensor? the breaker was off all night. yesterday I turned the machine on a couple times after lunch and the 701 came up, sometimes with the 401 alarm, sometimes just the 701.
So, my questions are:
1. Is there a faster/better/correct way to clear the 401 vrdy signal off alarm?
2. Is there any way to clear the 701 fan motor alarm? is my temp sensor dead? is there any way I can check without a VOM? can I bypass or override this any way?
Thanks for any help!
