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 SSI Encoder Input Unit with the MC Func-
tion Module.
The functions of the MC Function Module are related to the information in the process data objects.
Use the default Sysmac Studio settings to use the SSI Input Unit with the MC Function Module.
