Safety Messages
For the best results with the MX2-A@Inverter, carefully read this manual and
all of the warning labels attached to the Inverter before installing and operat-
ing it, and follow the instructions exactly. Keep this manual handy for quick ref-
erence.
Definitions and Symbols
A safety instruction (message) includes a "Safety Alert Symbol" and a signal
word or phrase such as WARNING or CAUTION. Each signal word has the
following meaning:
!HIGH VOLTAGE Indicates a potentially hazardous situation which, if not avoided, could result
in electric shock. It calls your attention to items or operations that could be
dangerous to you and other persons operating this equipment.
Read the message and follow the instructions carefully.
!WARNING Indicates a potentially hazardous situation which, if not avoided, could result
in death or serious injury. Additionally, there may be severe property damage.
!Caution Indicates a potentially hazardous situation, which, if not avoided, may result in
minor or moderate injury, or property damage.
Step 1 Indicates a step in a series of action steps required to accomplish a goal. The
number of the step will be contained in the step symbol.
Note Notes indicate an area or subject of special merit, emphasizing either the
product's capability or common errors in operation or maintenance.
Tip Tips give a special instruction that can save time or provide other benefits
while installing or using the product. The tip calls attention to an idea that may
not be obvious if you are a first-time user of the product.
1 Hazardous High Voltage
!HIGH VOLTAGE Motor control equipment and electronic controllers are connected to hazard-
ous line voltages. When servicing drives and electronic controllers, there may
be exposed components with housing or protrusions at or above line potential.
Extreme care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use only one hand when
checking components. Always work with another person in case an emer-
gency occurs. Disconnect power before checking controllers or performing
maintenance. Be sure equipment is properly grounded. Wear safety glasses
whenever working on electronic controllers or rotating machinery.

General Precautions - Read These First!
2 General Precautions - Read These First!
!WARNING Failure to read and understand the information provided in this manual may
result in personal injury or death, damage to the product, or product failure.
Please read each section in its entirety and be sure you understand the infor-
mation provided in the section and related sections before attempting any of
the procedures or operations given.
!WARNING This equipment should be installed, adjusted, and serviced by qualified elec-
trical maintenance personnel familiar with the construction and operation of
the equipment and the hazards involved. Failure to observe this precaution
could result in bodily injury.
!WARNING Wiring, maintenance or inspection must be performed by authorized person-
nel. Not doing so may result in electrical shock or fire.
!WARNING Hazard of electrical shock! Disconnect incoming power before working on the
OMRON 3G3AX-MX2-DRT-E DeviceNet Option Board or the MX2-A@
Inverter.
!HIGH VOLTAGE Turn the power supply OFF and wait for the time specified on the Option
Board front cover before performing wiring, maintenance or inspection. Not
doing so may result in electrical shock.
The OMRON 3G3AX-MX2-DRT-E DeviceNet Option Board is attached to an
MX2-A@Inverter. Dangerous voltage exists until the MX2-A@Inverter power
light is OFF.
!HIGH VOLTAGE Do not touch the conductive parts such as the internal PCB, terminals or con-
nector while power is being supplied. Doing so may result in electrical shock.
!WARNING Do not attempt to take an Option Board apart or touch any internal parts while
the power is being supplied. Doing so may result in electric shock.
!WARNING Do not attempt to disassemble, repair, or modify an Option Board. Any
attempt to do so may result in malfunction, fire, or electric shock.
!WARNING Provide emergency stop circuits, interlock circuits, limit circuits and similar
safety measures in external circuits (NOT in the Option Board). This ensures
safety in the system if an abnormality occurs due to malfunction of the Option
Board or another external factor affecting the Option Board operation. Not
doing so may result in serious accidents.
!WARNING Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes. Not doing so may result in
serious accidents.
!Caution Do not touch the Inverter during power on, and immediately after power off.
Hot surface may cause injury.

Installation Precautions
!Caution The product will be used to control an adjustable speed drive connected to
high voltage sources and rotating machinery that is inherently dangerous if
not operated safely. Interlock all energy sources, hazardous locations, and
guards in order to restrict the exposure of personnel to hazards. The adjust-
able speed drive may start the motor without warning. Signs on the equipment
installation must be posted to this effect. A familiarity with auto-restart settings
is a requirement when controlling adjustable speed drives. Failure of external
or ancillary components may cause intermittent system operation, i.e., the
system may start the motor without warning or may not stop on command.
Improperly designed or improperly installed system interlocks and permis-
sives may render a motor unable to start or stop on command.
3 Installation Precautions
!WARNING Always connect the grounding cable to one of the ground terminals of the
MX2-A@Inverter. Failure to abide could lead to serious or possibly fatal injury.
!Caution Failure to observe these precautions could lead to faulty operation of the
Option Board or the Inverter, or could damage either of the two. Always read
these precautions.
• Install external breakers and take other safety measures against short-cir-
cuits in external wiring. Not observing this may result in burning.
• Be sure that all cable connector screws are tightened to the torque speci-
fied in the relevant manuals. Incorrect tightening torque may result in mal-
function.
• Do not allow metal clippings to enter either Option Board or Inverter when
wiring or installing the unit.
• Follow the network configuration and wiring instructions provided in the
DeviceNet Operation Manual (Cat. No. W267):
• Wire the DeviceNet cables and connectors correctly. Incorrect wiring
may result in burning.
• Always connect a Terminating Resistor at the prescribed locations of
the DeviceNet network to ensure the quality of the transmission path.
Do not apply termination anywhere else.
• Be sure that the Option Board is mounted correctly. Improper mounting
may result in malfunction.

SECTION 1
Getting Started
1-1 Introduction
1-1-1 Main Features
The 3G3AX-MX2-DRT-E allows controlling, monitoring and parameterization
of an MX2-A@Inverter via a DeviceNet network. The 3G3AX-MX2-DRT-E
serves as a gateway that passes communicated register values from the
DeviceNet network to the MX2-A@Inverter and vice versa. The
3G3AX-MX2-DRT-E adheres to the DeviceNet / CIP AC Drive profile.
The following functions are available via DeviceNet communication by install-
ing the 3G3AX-MX2-DRT-E:
Cyclic Data Exchange The DeviceNet Master and 3G3AX-MX2-DRT-E can exchange data via a
DeviceNet Remote I/O connection:
• Output data (from DeviceNet Master to 3G3AX-MX2-DRT-E):
E.g. Run/stop, Reference frequency and Fault reset.
• Input data (from 3G3AX-MX2-DRT-E to DeviceNet Master):
E.g. Inverter status, Output frequency and Output current, etc.
Inverter Parameter Access The DeviceNet Master can read and write parameter data via the
3G3AX-MX2-DRT-E using the explicit message communication.
The inverter parameters are accessible in multiple ways:
• Access based on Function code
• Access based on the Modbus register address
Several AC Drive profile attributes can also be accessed using the explicit
message mechanism.
Simplified Start-up The 3G3AX-MX2-DRT-E can be set up easily, just by wiring the Unit, setting
the DeviceNet node address (P192) and the default connection path (P046)
and restarting the unit. The Unit’s configuration is read automatically when the
power is turned ON or after a reset. It is not necessary to make any settings
with a special Programming Device.
Simplified Replacement All parameters required by the 3G3AX-MX2-DRT-E are stored in the MX2-A@
Inverter. The 3G3AX-MX2-DRT-E can be replaced, requiring no re-configura-
tion.
Automatic Baud Rate
Recognition
The 3G3AX-MX2-DRT-E automatically detects the Master’s communication
baud rate, and no user configuration is required.
Note If the DeviceNet Master Unit’s baud rate changes, reset the Master Unit and
be sure to turn OFF and ON or reset the 3G3AX-MX2-DRT-E and other con-
nected Slave Units to detect the new baud rate.

1-3 Introduction to DeviceNet
1-3-1 Overview of DeviceNet
DeviceNet is a multi-bit, multi-vendor network that combines control and mon-
itoring on a machine/line-control level and that conforms to DeviceNet open
field network specifications. DeviceNet is a member of a family of networks
that implements the Common Industrial Protocol (CIP) at its upper layers.
Two types of communications are supported to provide a single point of con-
nection for both control and configuration:
1. Time-critical control remote I/O communications that automatically transfer
between the Master Unit/CPU Unit and the remote Slave Units, and
2. Explicit message communications that read/write messages, control oper-
ation, or perform other functions to the Slave Units. Message communica-
tions are achieved by executing specific instructions from the program in
the CPU Unit to which the Master Unit is mounted.

1-3-2 What is the AC Drive profile
Within DeviceNet/CIP standard, multiple device profiles have been defined.
Therefore the devices which adhere to a certain device profile are compatible
and replaceable in a multi-vendor environment.
The AC Drive device profile (profile code 0x02) supplements the DeviceNet/
CIP standard. It defines a unified behaviour and technique to access Inverter
and drive device data. All drives supporting the AC Drive profile respond the
same way to control instructions.
