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".

Input the 24 V power source. Always wire the CPU Rack and Expansion Rack to the same power supply.
This is the Unit at the center of the motion control, which executes the motion program.
Expansion Master Unit. Connect this Unit adjacent to the right side of the CPU Unit in the Expansion Rack.
Axis Interface Unit. For axis control, connect this to a Servo Drive and encoder.
Digital I/O Unit. You can add 16 digital inputs and 16 digital outputs.
