System Configurations
Basic System Configuration
CK3W Unit Configuration (CPU Rack/Expansion Rack)
The following shows the configuration of CK3W Units.
CPU Rack
The CK3W Unit configuration in the CPU Rack consists of a Power Supply Unit, CPU Unit, CK3W-AX Unit, CK3W-MD Unit, CK3W-AD Unit, and
End Cover.
Up to four CK3W Units (or up to two CK3W-AX Units) can be connected to the CPU Unit.
Expansion Rack
One Expansion Rack can be connected per CPU Unit.
To connect an Expansion Rack, use the Expansion Master Unit (CK3W-EXM01) and Expansion Slave Unit (CK3W-EXS02).
Up to four CK3W Units (or up to two CK3W-AX Units) can be installed to the Expansion Rack.
Connect the Expansion Master Unit (CK3W-EXM01) adjacent to the right side of the CPU Unit. Connect the Expansion Slave Unit (CK3W-EXS02)
adjacent to the right side of the Power Supply Unit.
Unless the Expansion Master Unit (CK3W-EXM01) is connected adjacent to the right side of the CPU Unit, the Sys.Status register CK3WConfigErr
becomes “5”.
Letter Configuration Remarks
A Power Supply Unit Input the 24 V power source. Always wire the CPU Rack and Expansion Rack to the same power supply.
B CK3M-series CPU Unit This is the Unit at the center of the motion control, which executes the motion program.
C CK3W-EXM01 Expansion Master Unit. Connect this Unit adjacent to the right side of the CPU Unit in the Expansion Rack.
D CK3W-AX Unit Axis Interface Unit. For axis control, connect this to a Servo Drive and encoder.
E CK3W-MD Unit Digital I/O Unit. You can add 16 digital inputs and 16 digital outputs.

EtherCAT Network Configuration
The EtherCAT network configuration consists of a Power Supply Unit, CPU Unit, End Cover, and EtherCAT slaves.
Use the built-in EtherCAT port on the CK3M-series CPU Unit to connect EtherCAT slaves.
EtherCAT is synchronized with the servo cycle of the CK3M-series CPU Unit. This enables acquisition of the I/O data of slave terminals that are
synchronized with the servo cycle.
F CK3W-AD Unit Analog Input Unit. You can add 4 or 8 voltage inputs.
G End Cover Must be connected to the right end of the CPU Rack and Expansion Rack. The CPU Unit and the Expansion Slave Unit are
each provided with one End Cover.
H CK3W-EXS02 Expansion Slave Unit. Use this in the Expansion Rack. Connect this Unit adjacent to the right side of the Power Supply Unit.
I Expansion cable Use this cable to connect the Expansion Master Unit and the Expansion Slave Unit. The cable length is 30 cm. Be sure to
use the CK3W-CAX003A (30 cm) cable.

Wiring
Applicable Wires
The wires that you can connect to the terminal block are twisted wires, solid wires, and ferrules that are attached to the twisted wires. The following
section describes the dimensions and processing methods for applicable wires.
Using Ferrules
If you use ferrules, attach the twisted wires to them.
Observe the application instructions for your ferrules for the wire stripping length when attaching ferrules.
Always use plated one-pin ferrules. Do not use unplated ferrules or two-pin ferrules.
The applicable ferrules, wires, and crimping tools are listed in the following table.
Using Twisted or Solid Wires
Required Tools
Use a flat-blade screwdriver to remove wires.
The recommended screwdriver is as follows.
