NOTE
1 The cable can be up to 100 m long (for the
FANUC- recommended cable for movable
sections, up to 50 m). Do not make the cable
longer than necessary.
2 There are two types of commercially available
cables: straight-connection and cross-connection
types. Select an appropriate cable according to
the purpose.
Cable Materials
Many cables without a shield (UTP cables) are commercially available
as twisted pair cables conforming to 10BASE-T or 100BASE-TX.
To improve noise immunity in factory automation environments,
however, be sure to use twisted pair cables (STP cables) with a
common shield in category 5.
