The FANUC I/O Link can be extended to the maximum length of 200 m
with optical fiber cables using an optical I/O Link adapter. The length of
the electrical cable connected to the optical conversion adapter must not
exceed 2 m.
In the following cases, use an optical fiber cable.
D When the cable is more than 15 meters long.
D When the cable is run between different cabinets, and the cabinets
cannot be connected with each other via a ground wire of 5.5 mm
2
or
more.
If the power magnetics cabinet includes an I/O Link slave unit, and
cables are connected through a duct to the operator’s panel (as shown
below), the control section I/O Link slave unit can be assumed to be
incorporated in the same cabinet.
