A-3-2 Settings for Encoder Input Terminals
There are two counter channels, and there are two external latches for each channel. Wire the input
signals that are required for your application.
Refer to the GX-series EtherCAT Slave Units User’s Manual (Cat. No. W488) for input signal wiring
methods.
This section describes mapping PDOs 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 PDO map is a list of required objects that is prepared in advance.
You select the PDOs to use in the Edit PDO Map Settings Window of the EtherCAT Tab Page in the
Sysmac Studio.
The following PDOs are mapped by default in the Sysmac Studio.
If you use the recommended Encoder Input Terminals (GX-EC0211/EC0241, version 1.1 or
later), then it is not necessary to change the default PDO map on the Sysmac Studio.
