Mitsubishi specifies a maximum cable length depending on the data
transfer rate. For more detailed information refer to documentation of
CC-Link by Mitsubishi.
Data transfer rate
Total bus distance
10 MBit/s
100 m
5 Mbit/s
150 m
2.5 MBit/s

Table 3-3
Cable length in relation to the baud rate
For fault-free operation of the CC-Link bus, the bus cable must be
terminated with resistors 110
Ω
or 130
Ω
(depending on cable type;
refer to Table 3-2) at both ends.

bus)
♦
When stripping off the insulation of the shield, make sure that the
shield is not damaged!
♦
When stripping off the insulation of the core ends, make sure that
the copper core is not damaged!
♦
Use terminal resistors 110
Ω
or 130
Ω
(depending on cable type;
refer to Table 3-2) at both ends of the CC-Link network. If CBL is
placed at the end of CC-Link bus, connect the resistor with the
clamp terminals DA and DB and fix them.
♦
Fix the terminal clamp connector with the two screws at CBL.
♦
The pins SLD and FG are connected to field ground by the fixing
screws of the CBL. Look into the chapter "EMC measures" for right
shielding! The connector FG is an additional point to connect to field
ground.
♦
The shield of the cable must be connected to the inverter housing.
