Fanuc 21-t error 414 servo alarm

[elcfede]

Hello....I have problems with the control of my fanuc 21-t lathe.
I would like to know if you can advise me because in my small country there is no fanuc specialist technician....
¡¡¡¡¡¡thank you very much!!!!!!
data: sometimes when you leave the lathe on for 30 minutes or 1 hour with this error when you turn it off and turn on the lathe again the error disappears but then when you run the g code in automatic mode it works for a few minutes and then the lathe stops and the error 414 servo alarm appears again....
---------------------------------------------------------------------------------
Alarm code: 1 on fanuc servo drive A06B-6079
-------------------------------------------------------------------------------------------------
On the lathe control panel : 414 servo alarm : x axis detec err
414 servo alarm : axis detec err
Any advice on what it could be?

the EXP alarm is related to encoders
as i checked my info i see there are 2 fans mounted on that driver.
did you plugged out the control PCB to check if is any fan on the PCB?
