Fuse 14 is the DC side of the drive. There is also a AC fuse for that axis. FUSE 17. It is in the back cabinet along with the saturable core reactors which is what you may be refering to. Try turning the ACC board upside down, CAREFULLY! It control the current to each axis. It is symmetrical and will swap the X and Z circuit on that board. The Y will still function with the Y.
