SERCOS-II optical fiber
FAGOR supplies the fiber optic cables for SERCOS-II communications
between the group of drives and the CNC in a ring connection and in
lengths ranging from 1 to 100 meters. The cables between drives come
with the connectors for each module. For SERCOS-II connection under 40
m, use the fiber optic cable with polymer core. Its sales models are:
SFO- cable
T. H7/17 Range of SFO-  cables.

INFORMATION. The maximum length for fiber optic cables of the models
mentioned earlier for best performance is 40 meters.

INFORMATION. The SFO-FLEX-  fiber optic cables are compatible with
the SFO-  cables. The SFO-FLEX-  are more flexible.
NOTE. If the fiber optic cable for SERCOS communication between
modules is going to be moving (dynamic conditions), always use the SFO-
FLEX-  cable. The SFO-  cable will be enough for static conditions
(resting). The useful life span of a SFO-  cable cannot be guaranteed if it
is installed in applications where it works under dynamic conditions
(moving).
For SERCOS-II connection over 40 m, use the fiber optic cable with glass
core.Their sales model is:
SFO-3 SFO-5 SFO-7
Normal. It must only be used in systems under static con-
ditions where the minimum bending radius is 30 mm.
Use only in static conditions!
