*1. The I/O refreshing method is set according to the connected Communications Coupler Unit and CPU Unit.
*2. You can use the external input 0 as a latch input.
*3. You can use the external output 0 as an error counter reset output.
*4. These functions are supported when you also use the MC Function Module in the NJ/NX-series CPU Unit or the
      NY-series Industrial PC.
      For details, refer to the motion control user’s manual for the connected CPU Unit or Industrial PC.
      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.
