     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.
