1. Communication wiring
The method to connect a CC-Link detected cable and a GW unit CC-Link communication connector is
shown below.
Connecting cable
•
Make sure to connect the signal cables to designated pins (Refer to Fig. 1).
And tighten the connector surely to 0.5 to 0.6 Nm tightening torque.
•
Make sure to connect "terminating resistor" between "DA"-"DB" to the units at the both ends of the
system.
(Refer to Fig. 3)
•
The connected terminating resistor differs depending on used cable in system.
See the table below.
Cable type
Terminal resistor
CC-Link dedicated cable
CC-Link dedicated cable compatible with Ver.1.10
110
Ω
1/2 W (brown, brown, brown)
CC-Link dedicated high performance cable
130
Ω
1/2 W (brown, orange, brown)
•
Refer to Fig. 4 about how to connect to the unit.
Tighten the connector securely to 0.5 to 0.6 Nm tightening torque.
NOTE
1. CC-Link dedicated high performance cable cannot be mixed with other cables (CC-Link
dedicated cable, CC-Link dedicated cable compatible with Ver.1.10).
If mixed, normal transmission of data cannot be assured.
2. Connect the shield line of CC-Link dedicated cable to "SLD" of each unit.
