For details of the laying of the communication cable, refer to the CC-Link Laying Manual, etc.
CAUTION
Be sure to use special signal cables complying with the CC-Link specifications.
Before inserting the cable into the connector, loosen the cable fixing screw sufficiently
to avoid the cable entering the back side of the connector instead of the connector
tightening side.
For the shield wires for CC-Link special cables, connect to “SLD” of each unit via “FG”
and ground with class D (level III grounding resistance of 100
Ω
or lower) SLD and
FG are connected inside the unit.
For those provided with a connector fixing screw, securely tighten the connector fixing
screw when inserting the connector. Otherwise the connector may be dislocated and
cause malfunction. For those not provided with a connector fixing screw, check that the
catch of the connector snaps in position.
Loosen the two fixing screws before removing the connector. The connector may be
damaged if excess force is applied to the connector without the two screws loosened.
Do not bend the communication cable forcibly. Assure a sufficient bending radius.
Remove the connector vertically to avoid excess force from being applied to the
connector.
Reserve a sufficient distance between the communication cable and power cable
(motor cable).
If the communication cable is routed near the power cable or if they are tied, noise will
enter to make communication unstable, possibly causing frequent communication
errors and/or communication retries.
