*1. The I/O refreshing method is automatically set according to the connected Communications Coupler Unit and CPU Unit.
*2. These functions are supported when you also use the MC Function Module in the NJ/NX-series CPU Unit.
Refer to the NJ/NX-series CPU Unit Motion Control User’s Manual (Cat. No. W507) for details.
A Pulse Output Unit only outputs pulses during the control period based on commands received at a fixed period.
Target position calculations (distribution calculations) for acceleration/deceleration control or for each control period must
be performed on the Controller that is connected as the host.
