8 Pulse Output Units
8 - 30
NX-series Position Interface Units User’s Manual (W524)
Set the parameters and assign I/O data for the user program from the Sysmac Studio.
Assign the I/O data in the NJ/NX-series Controller as device variables for the Unit.
Refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) for details.
Connect the Unit after the EtherCAT Coupler Unit, even if you do not use the MC Function Module.
The following table lists the usage restrictions for functions based on their combination with the Ether-
CAT Coupler Unit.
Yes: Can be used, Partial: Can be used with restrictions, No: Cannot be used
Precautions for Correct Use
• Connect the Unit after the EtherCAT Coupler Unit, even if you do not use the MC Function
Module.
• If you do not use the MC Function Module, operations related to the Position Interface Units,
such as latching, must be performed from the user program.
For Pulse Output Units, other tasks must be performed on the Controller in addition to position
management, such as velocity profile generation and control status management.
If you want to use a pulse output, we recommend that you use the MC Function Module
because it can automatically handle this control for you.
The Pulse Output Unit cannot be connected to other controllers.
