Limitations Caused by Inverter Mode and Rating Selection
The Inverter mode and rating selection directly affects several aspects of the
Option Board usage. Refer to the MX2 User’s manual section 3-6-24. The fol-
lowing table lists the most common consequences of the various Inverter
modes and ratings:
Note 1
The Inverter will trip due to a cyclic mapping fault if you use torque-related
registers in the process area when not available.

Monitoring additional Inverter status using COS
Typically the default DeviceNet Poll connection is used for controlling and
monitoring the main functions of the Inverter. For specific monitoring of
Inverter states, a second connection Change of State (COS) can be added.
We will use the Flexible format for this connection.
The following steps are based on configuration of the OMRON CJ1W-DRM21
Master Unit using CX-Integrator tool. The configuration must be done using
the user-set allocation method.
Step 1
Configure the Option Board and Network as explained in sections
3-1 Installa-
tion of EDS files
and
3-2 Configuring the Option Board
. Use the Advanced
Setting for the Slave to select both the Poll connection as the specific COS
connections.
Note 1
The output assembly of the COS connection is the same as for the Poll con-
nection, in this case assembly 21 Extended Speed Control.
Note 2
The default length of the 159 Flexible input is 20 bytes, you can change this as
explained in the next step.
