Notes
●Strip the insulation of signal wires to 7 mm. Do not plate the cable core with solder.
●Use dedicated cable for the CC-Link connection cable. Do not mix dedicated cables for CC-Link with dedicated high-performance cables for CC-Link. Normal data
transmission cannot be guaranteed if cables are mixed. Terminating resistance values vary depending on the type of specialized cable used.
●Connect the shielded cable of the CC-Link connection cable to "SLD" and connect "FG" to D-type ground (insulation resistance of 100 Ω or less). "SLD" and "FG" are
connected inside the unit.
●Always be sure to use dedicated wire for CC-Link communication wires, and satisfy the requirements for overall wiring and inter-station wiring distances, and terminating
resistance values in accordance with the baud rate (B RATE). Failure to use dedicated wire or to satisfy the wiring conditions can result in communication error. (Refer to the
operation manual included with the CC-Link master unit for dedicated wires and wiring conditions.)
●Units on both ends of a CC-Link communication line must always be installed with the terminating resistance of that attached to the CC-Link master unit. Connect between
the DA and DB terminals if there is an energy measuring unit at the end of the CC-Link communication line.
●Terminating resistance values vary depending on the type of dedicated cable used for CC-Link. Refer to the terminating resistance manual packaged with the CC-Link master
unit.
Setting Procedures
When connecting this unit to a CC-Link communication line, specify a different station number (STATION) for each unit, and also specify the transmission speed (B RATE) and
CC-Link version (VER.) before energization. Always be sure to specify a station number and transmission speed because devices having a CC-Link communication function
perform mutual communication using station numbers at the specified transmission speed.
CAUTION
9.1 Setting the Station (STATION) 9.1 Setting the Station (STATION)
◎This unit is a remote device station occupying one station. The station number can be specified in a
range from "1" to "64".
◎The station number is the total of the values of station-number setting switches that are on.
◎Use a thin screwdriver or rod for switching on station-number setting switches.
◎For example, perform the following to specify number 36 as the station-number for this unit.
Turn on station-number setting switches 1 and 2 on the x10 side and 2 and 4 on the x1 side. (In the
figure, the direction of the arrow indicates ON.)
9.2 Setting the Transmission Speed (B RATE) 9.2 Setting the Transmission Speed (B RATE)
◎Use a thin screwdriver or rod for switching the B RATE setting switches.
◎The relationship between transmission speed and setting switches is as shown on the right.
*Do not set in any other manner than that shown on the right because any other combination will result in an error.
9.3 Setting the CC-Link Version (VER.) 9.3 Setting the CC-Link Version (VER.)
Use a flat thin screwdriver for switching the VER. setting switches.
◎
The relationship between CC-Link version and setting switches is as shown
◎
on the right.
*The setting is fixed as one occupied octuplex station when set to Ver. 2.00.
Press the RESET switch if you set or change the station number, transmission speed or CC-Link version after operating the equipment.
The RESET switch must be pressed to enable the specified settings.
◎
It takes a few seconds for reset to be performed. Press and hold the RESET switch while checking for the L RUN LED to turn off before releasing
◎
the switch.
Notes
●The lengths of inter-station cables and maximum total cable length vary depending on transmission
speed.
●Do specify stations so that there are two identical station numbers within the same transmission path.
The existence of two identical station numbers will result in an error.
●Number of units which can be connected to CC-Link is determined by conditions 1 and 2 described
on the right, and both conditions need to be satisfied.
A maximum of 42 units can be connected with this module. (Only when connected as a remote device
station occupying one station.)

CC-Link Communication Unit
①Rotate the levers on both ends of the CC-Link communication connector and remove
it from this unit.
②Loosen the cable-clamping screw of the CC-Link communication connector.
Use a thin flat-head screwdriver (tip thickness: 0.6mm; total length: 3.5 mm)
③Insert the signal wire according to the indications on the side of the CC-Link
communication connector.
④Fix the wire using the cable-clamping screw. (Recommended torque: 0.5 to 0.6 N/m)
Lever
⑤Insert the CC-Link communication connector into its original position and secure
using the levers on both ends.

・ Do not use a mechanical pencil to switch the address setting or transmission speed switches. Broken lead or dust could get
into the internal circuits, resulting in misoperation or malfunction.
・ Press the RESET switch with appropriate force (1.6 N). Do not apply excessive force as doing so can result in a malfunction.
