Fagor DDS Series Hardware Manual page 301

If a drive is assigned the 0 identifier, the module will be ignored.
Example
For example, a machine has four drives identified as 1, 2, 3 and 4. To ignore
the second one, another one must be renamed so they are consecutive. The
easiest solution for a situation like this will be 1, 0, 3 and 2.
NOTE. Remember that the DRIBUSID parameters of the CNC can also
be modified the same way.
Interconnection
Connect in the CAN field bus all the drives that will be governed by the CNC.
 Use the CAN cable to connect the first drive to the adjacent one (this one
will then be the second drive) through their X6 connectors.
 Repeat this procedure with the second drive and so on up to the last
drive.
 Use a CAN cable to connect the X6 connector of the first drive to the
CAN connector of the CNC model being used.
NOTE. Note that the CAN cable is supplied without connectors. Before
connecting it, put the cable and connectors together as indicated in figure
F. H8/38 .

CAN cable to connect a CNC and two drives.
NOTE. Note that the connectors of the intermediate modules (when
connecting several drives in the bus) receive two wires, in each pin of the
CAN connector, coming from each adjacent module. The connectors of the
modules at either end only receive one.
Making all these connections will conclude the connection process. See
figure.

Pay attention to this
wire crossing when
connecting the cables.

NOTE. No more than six drives (axes+spindles) can be connected in the
CAN BUS.
WARNING. The bending radius of the CAN cable must always be more than
50 mm.
