2 System Configuration
2-1
Basic Configuration
A Motion Controller supports the following two types of configurations.
• Basic Configuration
The basic configurations include the CPU Unit and the Configuration Units that are controlled direct-
ly by the CPU Unit. There are two basic configurations.
a) CK3W Unit Configuration
b) EtherCAT network configuration
• Other Network Configuration
This is the configuration of the system that is connected to the CPU Unit's built-in Ethernet port.
Basic System Configurations
 CK3W Unit Configuration
The CPU Rack is configured with CK3W Units.
In addition to the CPU Rack, an Expansion Rack can be used to install additional CK3W Units.
Motion control is enabled by connecting a DirectPWM type Servo Drive, an analog input type Servo
Drive, or a stepper motor to the Axis Interface Unit.
 EtherCAT Network Configuration
The CK£M series CPU Unit can be connected to an EtherCAT network.
Motion control is enabled by connecting an EtherCAT type Servo Drive to the CPU Unit.
2-1-1
CK£W Unit Configuration
The following shows the configuration of CK£W 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, CK3W-ECS Unit, CK3W-GC 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
Up to one Expansion Rack can be added for the CK3M CPU Unit, and up to three Expansion Racks
can be added for the CK5M CPU Unit.
To connect an Expansion Rack, use the Expansion Master Unit (CK3W-EXM01) and Expansion Slave
Unit (CK5W-EXS01, 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) to the immediate right side of the CPU Unit. Con-
nect the Expansion Slave Unit (CK5W-EXS01, CK3W-EXS02) to the immediate right side of the Pow-
er Supply Unit.
