Option Board Description
The 3G3AX-MX2-EIP-A is an option board which can be attached to an
MX2-A□ series inverter. The 3G3AX-MX2-EIP-A allows controlling,
monitoring and parameterization of the inverter via an EtherNet/IP
network. The application in the system that acts as an EtherNet/IP master
is responsible for correct behaviour of the system. The 3G3AX-MX2-EIP-A
is a gateway that passes the communicated register values from the
EtherNet/IP network to the inverter and vice versa.
MX2 Inverter Support
Install the module. The drive firmware version can be read from the web
pages of the module using any web browser. If the version is 43.09, only
limited functionality is available. If the version is 43.23 or higher, there is
full compatibility.
MX2 Inverter Safety (ISO 13849-1)
MX2-A□ inverters provide the Gate Suppress function to perform a safe
stop according to the EN60204-1, stop category 0. The option board has
been designed not to interfere with this safety function.

Installation Procedure
Follow the next steps to install a 3G3AX-MX2-EIP-A on an MX2-A□ series
inverter:
1. Power down the inverter
2. Loosen the screw of the option board cover on the inverter, remove
the cover and put the cover aside
3. For inverters up to 4.0 kW only: loosen the screws of the terminal
block cover and remove the cover to enable access to the chassis
ground terminal screws
4. Connect the grounding cable to the chassis ground of the inverter
(located on the cooling fin)
5. If removed, mount the terminal cover again and tighten the screw(s)
6. Push the 3G3AX-MX2-EIP-A option board into the previous location
of the option board cover until it clicks into place
7. Tighten the screw of the option board (do not over-tighten).
8. Select the right warning language from the warning label sheet and
replace the English warning if appropriate.
9. To assign an IP address, set the rotary switches (see chart for IP
Settings Rotary Switches) and power up the inverter, the network
and the PLC or EtherNet/IP master unit. For other option board
related inverter parameters see below
EDS File and CX-Integrator
OMRON provides a series of EDS files for the 3G3AX-MX2-EIP-A option
board via the OMRON website. For each of the MX2 inverter type there is
a unique EDS file, which is named:
3G3AX-MX2-EIP-□-E.eds
□ indicates the specific inverter type, such as A4150 or AB004_A2004.
Use these EDS files in the EtherNet/IP master configuration program used
to configure your EtherNet/IP master.
Network Configurator for EtherNetIP in the CX-One Suite is the
configuration program for OMRON EtherNet/IP masters. Start the
configurator and select the Tools/EDS File/Install menu item. Select the
EDS file(s) to start using the 3G3AX-MX2-EIP-A together with OMRON
EtherNet/IP masters.
Supported Modules and I/O Register Layout
The 3G3AX-MX2-EIP-A supports the modules as listed in the EDS file.
