Fanuc R-J3iB

I have a R-j3ib controller and am having some issues getting it up and running. Currently I am receiving a Servo 264 circuit abnormal 1.

Has anyone received this alarm before, and if so, how did you fix it?

I checked those connections and I am missing the CRM72 cable. Do you by chance know where this is supposed to be connected?

Tanks for your help!
