Supplementation --------------------------------------------------------------------------------------------------------------------------------------------------------------
Use the specified cable for CC-Link connection. The dedicated CC-Link cable and dedicated CC-Link high-performance cable must not
be used simultaneously. If the cables are used simultaneously, correct data transmission cannot be assured.
The terminal resistance shows different resistance value depending on the type of the dedicated cable.
Connect the shielded wire of the CC-Link connection cable to "SLD," and ground "FG" according to Class D grounding (Class 3
grounding). "SLD" and "FG" are connected in the unit.
The CC-Link transmission line is a small signal circuit. Lay the line at a distance of 10 cm or more from any heavy current circuit. If the
line is laid in parallel with such a circuit over a long distance, lay the line 30 cm or more away from the circuit. When using, ground the
FG terminal.
As the CC-Link communication line, use a dedicated line, and ensure that the total wiring distance, station-to-station distance and
terminal resistance are appropriate to B RATE. If a dedicated line is not used or any wiring requirement is not met, normal
communication may not be made. (For the dedicated line and wiring requirements, see the instruction manual for CC-Link master unit.)
It is necessary to fit the terminal resistance supplied with the CC-Link master unit to the units on both sides of the CC-Link
communication line. When the measuring unit is connected at an end of the CC-Link transmission line, connect it between the terminals
DA and DB.
The terminal resistance varies depending on the type of the CC-Link cable to be used. See the manual for the terminal resistance
supplied with the CC-Link master unit.
