V-CNC 750
Fanuc 21i-MB

After a series of unfortunate events, (tool drum switch failure, short resulting in blown fuse, and loss of bettery) I finally got the machine to come back to life but now it needs all 3 axes aligned. On start up I get the following error mesages:

300 APC ALARM: X AXIS NEED ZRN
300 APC ALARM: Y AXIS NEED ZRN
300 APC ALARM: Z AXIS NEED ZRN

Reset will not clear them and when I try to do anything it says "ALIGN AXES FIRST."
I've searched through my manuals and can't find anything. I found the alarm number in one of my Fanuc manuals but it just says axis alignment has been lost, needs realignment. Gee thanks Fanuc manual. That was super helpful.
Has anyone run into this problem or know the procedure?
