Description
(A)
Support Software (Sysmac Studio)
(B)
Connection to the peripheral USB port or built-in EtherNet I/P port on an NJ/NX-series CPU Unit
(C)
EtherCAT master (NJ/NX-series CPU Unit)
(D)
EtherCAT communications cable
(E)
EtherCAT Coupler Unit
(F)
Pulse Output Unit
(G)
Digital Input Unit
(H)
External inputs
*1
(positive limit input, negative limit input, home proximity input, and immediate stop
input)
*1. When the Unit is connected to an NJ/NX-series CPU, you can use these inputs by adding a Digital Input Unit
and assigning MC Function Module functions. For information on Digital Input Units, refer to the
NX-series
Digital I/O Units User’s Manual
(Cat. No. W521).
(I)
Latch inputs (Latch input 1 and latch input 2)
(J)
Current-limiting resistor
*2
*2. The pulse output from a Pulse Output Unit is a 24-VDC open collector output. Connect an external current-lim-
iting resistor according to the input specifications of the connected motor drive.
Example: For a G5-series Servo Drive, connect a 2-k
Ω
(1/2-W) resistor in series.
