System Configurations
Connected to a CPU Unit
The following figure shows a system configuration when NX Units are connected to an NX-series CPU Unit.
Connected to an EtherCAT Coupler Unit
The following figure shows an example of the system configuration when an EtherCAT Coupler Unit is used as a Communications Coupler Unit.
*1. The connection method for the Sysmac Studio depends on the model of the CPU Unit or Industrial PC.
*2. An EtherCAT Slave Terminal cannot be connected to any of the OMRON CJ1W-NC@81/@82 Position Control Units even though they can
operate as EtherCAT masters.
Note: To check whether NX Units can be connected to your CPU Unit or Communications Coupler Unit, refer to the version information.

Applicable Wires
Using Ferrules
If you use ferrules, attach the twisted wires to them.
Observe the application instructions for your ferrules for the wire stripping length when attaching ferrules.
Always use plated one-pin ferrules. Do not use unplated ferrules or two-pin ferrules.
The applicable ferrules, wires, and crimping tool are given in the following table.
*1. Some AWG 14 wires exceed 2.0 mm2 and cannot be used in the screwless clamping terminal block.
When you use any ferrules other than those in the above table, crimp them to the twisted wires so that the following processed dimensions are
achieved.
Using Twisted Wires/Solid Wires
If you use the twisted wires or the solid wires, use the following table to determine the correct wire specifications.
*1 Secure wires to the screwless clamping terminal block. Refer to the Securing Wires in the USER'S MANUAL for how to secure wires.
*2 With the NX-TB@@@1 Terminal Block, use twisted wires to connect the ground terminal. Do not use a solid wire.
<Additional Information> If more than 2 A will flow on the wires, use plated wires or use ferrules.

The cable length from the Unit to an external device connected through the Connector-Terminal Block Conversion Units should not be longer than
the specified cable length for the Unit.
Refer to the Specification for each units.
Connector-Terminal Block Conversion Unit
The table below shows applicable Connector-Terminal Block Conversion Units.
Each of NX-PG0232-5 and NX-PG0242-5 has one MIL connector. Therefore, one Connector-Terminal Block Conversion Unit is required.
Each of NX-PG0332-5 and NX-PG0342-5 has two MIL Connectors. Therefore, two Connector-Terminal Block Conversion Units are required.

*1. The I/O refreshing method is automatically set according to the connected Communications Coupler Unit and CPU Unit.
Refer to information on the I/O refreshing methods in the W524 manual for the communications cycles for each model.
*2. The maximum transmission distance for an SSI Input Unit depends on the baud rate due to the delay that can result from the responsiveness
of the connected encoder and cable impedance. The maximum transmission distance is only a guideline. Review the specifications for the
cables and encoders in the system and evaluate the operation of the equipment before use.

*1. When the Unit is connected to an NJ/NX-series CPU, you can use these inputs by assigning MC Function Module functions to external inputs inside
a Pulse Output Unit or to inputs of a Digital Input Unit that is added. For information on Digital Input Units, refer to the
NX-series Digital I/O Units User’s

inputs that can be used in always ON status is restricted by ambient operating temperature and installation orientation.
*2. The pulse output from a Pulse Output Unit is a 24-VDC open collector output. When it is used as a control output for a motor drive such as an
error counter reset output, connect an external current-limiting resistor according to the input specifications of the connected motor drive. A
line drive output does not need a current limiting resistor.

Pulse Output Unit (Line driver output, PNP type) 2 channels NX-PG0242-5
*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.
