    Need a lot more details. EX is a machine side alarm, how about the display on the spindle drive itself? In fact, that EX alarm number sounds like a mori number.

    If its a alpha drive, since you still haven't posted the control type, alarm 1 indicates a bad fan inside the spindle drive unit.

    Sorry, I don't skype,facebook,twitter, or any of those sorta things. 0TT control could be alpha or C series drives. I'm not next to my computer with the fanuc manuals today. Post the part number of the spindle drive, i'm sure Al or someone else can look it up.

    You have to check X2.4
    X2.4=0 then alarm
    X2.4=1 no alarm
