DANGER
Do not use in locations with ignitable, flammable, or explosive substances or other such
dangerous substances.
There may be risk of ignition, combustion, or explosion.
Make sure that the product does not come in contact with water drops or oil drops.
Fire or damage may result.
When mounting the product, be sure to hold and fix it securely (including workpieces).
If the product is knocked over, falls, or experiences malfunction, it may lead to injury.
Use a DC stabilized power supply with surplus capacity (24 VDC ±10%) for the controller and
input/output circuit.
Connecting directly to an AC power supply may lead to fire, rupture, or damage.
WARNING
Design safety circuits or devices as the entire system including hardware in order to prevent
damage to the device or an accident resulting in injury or death in the event that a machine
stops due to system abnormality such as an emergency stop or a power failure.

2.1 Wiring method
WARNING
Perform the wiring with the power supply turned OFF.
Touching the electrical wiring connections (bare charger) may cause electric shock.
Do not touch the charger with bare hands.
Doing so may cause electric shock.
Read and fully understand this instruction manual before performing the electrical wiring.
CAUTION
Check the working voltage and polarity before wiring and energizing.
Take countermeasures against lightning surges in the equipment side.
The product is not resistant to lightning surges.
For an AC voltage, use it in the installation category 2.
Use a dedicated communication cable conforming to the EtherNet/ IP specifications.
Secure a sufficient bending radius of the communication cable to avoid excessive bending.
Separate the communication cable from the power line or high voltage line.

2.1.1 Connection and wiring to CN5 (interface connector)
This manual covers CN5 (interface connector) only.
EtherNet/IP is capable of the use of normal Ethernet cables and flexible wiring methods, but is limited by
the type of wiring, equipment, master, or hub to be used. Understand these specifications before
performing the wiring. For details, refer to the instruction manual of the master unit manufacturer or
ODVA.
A communication connector is not attached to this product. Purchase a communication connector that
meets the specifications separately.

3. USAGE
•When using the ECG-B Series, ensure to set the actuator information using S-Tools. Refer to
the S-Tools instruction manual (SM-A11147) for setting the information.
•To use S-Tools with the settings of the ECG-A Series or ECG-B Series, the S-Tools version
must be as follows:
ECG-A Series, ECG-B Series: Version 1.04.00.00 or later
3.1 Obtaining EDS files
In order for the EtherNet/IP device to join the network, an EDS (Electronic Data Sheet) file describing the
communication specifications of the device must be installed in the configuration tool of the master unit.
Refer to the instruction manual of the master unit manufacturer for how to install the EDS file. Use the
latest EDS file to configure an appropriate network.
EDS files are available on the website of CKD (https://www.ckd.co.jp/).
<How to obtain>
1 Select “COMPONENT PRODUCTS” from the “PRODUCT INFORMATION” tab or the “PRODUCT
INFORMATION” page.
2 Select “Electric actuator” in the product lineup.
3 Select “Stepper motor drive.”
4 Access the detail page of “Controller Model No. ECG” from the product list.
