First post but this forum has been SO helpful in the past as a surfer so thankyou.
I know this is a really old robot, its a fanuc M410iwx on an RJ2 controller, but I would like to get a bit more life out of her yet if poss. I kept getting SRVO 150 error first then it developed the SRVO 154 after I opened up the cpu to check out the cooling fan.
So far I have measured the voltage into the cpu at the connector input and its 239v, and also changed the cpu for a good second hand one (sold as working by a company at least). The SRVO-154 continues with the new CPU in place and also the SRVO 150 came back and went again after a switch off and on again.
The old cpu showed a 2 in the display, the new one does not show a number.
I'm a bit lost now but would really appreciate any input from members who may have had this in the past.
