NOTE
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.
(b)Cable Wires
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.
