·
When repeating actions to give the RUN command and frequency reference to the
Inverter and read the status of the Inverter, for example, the actions can be registered
as one sequence, or more than one if necessary. In
7-9-4 Creating a Project File
, an
example is shown with all actions registered as a single sequence.
·
A sequence may include the following parameters.
Parameter
Description
Transmission
control parameter
Set the method of control, such as flow control.
Note
Select only model control for communications with the 3G3MV.
Link word

Controller and Communications Board.
Note
In
7-9-4 Creating a Project File
, an example is shown without
such an area set.
Monitor time
Set the periods to monitor the transmission and reception steps with
timers Tr, Tfr, and Tfs.
Note
Set a period of approximately 0.5 s each for communications
with the 3G3MV.
