vectrix motor controller

motor controller burned out

Hi all.
Does anybody know if there is a circuit diagram of the vectrix motor controller available anywhere?
Also a partial diagram would help.
The center stud of the three motor connection studs has come loose , overheated and caused the PCB to burn black around the stud.
Unfortunately it has also burned the small IC right next to the "CAP1 1" labeled muRata capacitor.
The IC that is missing looks exactly like the "U18" right next to the "CAP 2" labeled muRata.
The big Bussmann 125A fuse was not blown.
