Interconnection
Connect in the SERCOS ring all the drives that will be governed by the CNC.
 With each fiber optic line, connect the OUT terminal of the first drive with
the IN terminal of the next adjacent drive.
 Repeat this procedure with the second drive and so on up to the last
drive.
 Connect the OUT terminal of the last drive with the IN terminal of the
CNC.
 Connect the IN terminal of the first drive with the OUT terminal of the
CNC.
When all these connections have been made, the ring will be closed. See
figure F. H8/28.
NOTE. With each drive, FAGOR supplies a fiber optic line to connect it to
its adjacent module and, upon request, the rest of the required optical fiber.
See chapter 7. CABLES .

Note. Remember that for sections longer than 40 meters, you must use
the fiber optic cable (SF0-V-FLEX).

General connection diagram for the SERCOS ring between the CNC and the
drives.
NOTE. Note that if the machine has two separate DDS system (each with
its own power supply) and a single CNC, the same ring must
interconnected all the drives of the machine.
WARNING. The bending radius of fiber optic cables SF0 and SF0-FLEX
must always be more than 30 mm. For SF0-V-FLEX cables, this radius must
be more than 60 mm.
