EX1061 is probably from a tripped breaker. Check where the electricians have been, they tend to trip them when they pull wire in to the cabinet. The fans Fanuc is talking about are actually inside the Servo amplifiers. Not a super easy fix, since you need to take the amps out and dissasemble them somewhat. I have only ever seen 1 fan in those myself, and they do have a speed feedback (yellow wire), so the fans are very common to cause this alarm, especially if the machine has been off for a while.
