6-8-3 Setting Examples
The default settings for the above parameters are for a general input and N.O. (normally open), respec-
tively.
Change the input function and input logic settings to use latching with the MC Function Module or in
other cases.
Refer to 6-9-9 External Input Function Selection on page 6-62 for information on external input signals.
This section describes I/O entry mapping to control encoder axes from the MC Function Module.
You must map the objects that are required for the motion control functions that you will use to process
data communications.
The I/O entry mapping is a list of required objects that is prepared in advance.
You select the I/O entry mappings to use in the Edit I/O Allocation Settings area of the Slave Terminal
Tab Page in the Sysmac Studio.
The following I/O entry mappings are selected by default in the Sysmac Studio.
Refer to A-2 Object Lists on page A-28 for details on each object.
Use the default Sysmac Studio I/O entry mappings to use the Incremental Encoder Input Unit with the
MC Function Module.
The functions of the MC Function Module are related to the information in the process data objects.
Use the Sysmac Studio defaults to use the Incremental Encoder Input Unit with the MC Function Mod-
ule.
