3-1 Inverter Configuration
To use the DeviceNet Communications Unit, you need to configure node addresses and the necessary
Remote I/O and other functions
The configuration of the DeviceNet Communications Unit is all done through parameters built into the
MX2-series inverter.
This section describes the inverter parameters that must be configured to use the DeviceNet
Communications Unit.
Because the settings of the DeviceNet Communications Unit vary depending on the type of the Remote
I/O function to be used, information in this section is described for each of the following three types of
Remote I/O.
Precautions for Correct UsePrecautions for Correct Use
For details about the Remote I/O function, refer to Section 4 Remote I/O on page 4-1.
Parameter configuration is required if you are installing the DeviceNet Communications Unit
on an MX2-series inverter for the first time.

retained and thus parameter configuration is not required.
Normally, Inverter operation can be controlled using the Basic Speed I/O or Extended Speed I/O function
included as standard in DeviceNet.
To set the acceleration/deceleration time, however, you need to use OMRON's unique Extended Speed
and Acceleration Control function.
This section explains how to configure these three types of Remote I/O.
Inverter parameters can be configured using the Digital Operator, CX-Drive, or a DeviceNet EDS file (in
