We're upgrading an enshu VMC 400 to 4 axis and have gotten as far as the 4th axis fanuc servo powers up and is held from rotating by the controller, however we can't move it in either direction with C axis switch. It can not be rotated by hand in either direction when the machine is turned on.
Does anyone know where/how to switch the it4 interlock signal, according to a Russian manual of this controller there's a connector named C03 in which #36 is supposed to enable/disable 4th axis interlock?
thanks
