!Caution
This section provides some common usage examples to help you get started.
Unless otherwise specified, all usage examples make use of the Extended
Speed IO format as the default connection path (Refer to section 3-1 Installa-
tion of EDS files, Step 2). Prepare the Inverter and Option Board before start-
ing with the usage examples:
Initialize the Inverter mode to Std. IM by first setting b171 = 1 and then
b180 = 1 (Refer to MX2 User's manual (Cat. No. I570) section 3-6-24).
Set the Inverter rating to CT (constant torque) by setting b049 = 0 (Refer to
the MX2 User's manual section 3-2-5).
Configure the Option Board and Network as explained in sections 3-1 Installa-
tion of EDS files and 3-2 Configuring the Option Board with Extended Speed
IO (Output assembly 21, Input assembly 71). There are two options:
• When using Fixed allocation method of configuring the master, select
P046 = 1.
• When using User-set allocation, select the two Extended Speed IO
assemblies.
If you configured everything correctly, your output and input I/O words should
contain the following data:

Check the Inverter settings for proper Inverter behaviour before actually oper-
ating the Inverter remotely via the network.
