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/IP 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
With a CK3M-series CPU Unit, you can use an EtherCAT network.
Motion control is enabled by connecting an EtherCAT type Servo Drive to the CPU Unit.

CK3W Unit Configuration

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. Con-
nect 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".
