CPU Unit
Accessories
The following accessories come with the CPU Unit.
Power Supply Units
One Power Supply Unit is required for each Rack.
Note: Power supply units for the CJ-Series cannot be used as a power supply for a CPU rack of the NJ system or as a power supply for an expansion rack.
Expansion Racks
CJ-Series I/O Control Unit (Mounted on CPU Rack when Connecting Expansion Racks)
Note: Mounting the I/O Control Unit in any other location may cause faulty operation.
CJ-Series I/O Interface Unit (Mounted on Expansion Rack)
Note: Mounting the I/O Interface Unit in any other location may cause faulty operation.
I/O Connecting Cables
Automation Software Sysmac Studio
The Sysmac Studio is the software that provides an integrated environment for setting, programming, debugging and maintenance of machine automation controllers including the NJ/NX-series CPU Units, NY-series Industrial PC, EtherCAT Slave, and the HMI.
For details, refer to your local OMRON website and Sysmac Studio Catalog (Cat. No. P138).

Typical Models
Recommended EtherCAT and EtherNet/IP Communications Cables
• Use a straight STP (shielded twisted-pair) cable of category 5 or higher with double shielding (aluminum tape and braiding) for EtherCAT.
• For EtherNet/IP, required specification for the communications cables varies depending on the baud rate.
• For 100BASE-TX/10BASE-T, use a straight or cross STP (shielded twisted-pair) cable of category 5 or higher.
• For 1000BASE-T, use a straight or cross STP cable of category 5e or higher with double shielding (aluminum tape and braiding).

Optional Products and Maintenance Products
There are restrictions on the combination of CPU Unit version and memory card. Refer to NJ/NX-series CPU Unit Software User’s Manual (W501) 8-5-2 Specifications of Supported SD Memory Cards, Folders, and Files for details.
General Specifications
1. This is the value when the power ON time rate is 0% (power OFF).
2. Consult your OMRON representative for the most recent applicable standards for each model.
3. Supported only by the CPU Units with unit version 1.01 or later.
Performance Specifications
1. When the hardware revision for the Unit is A or B.
2. When the hardware revision for the Unit is A.
3. This is the capacity for the execution objects and variable tables (including variable names).
4. Words for CJ-series Units in the Holding, DM, and EM Areas are not included.
5. The number of variables of the CPU Unit version 1.19 or earlier is 90,000.
6. The number of variables of the CPU Unit version 1.18 or earlier is 22,500.
7. Words for CJ-series Units in the CIO and Work Areas are not included.
8. When the Spool function of the NJ501-[][]20 is enabled, the DB Connection Service uses E9_0 to E18_32767 (NJ501-1[]20). When the Spool function of the NJ101-[][]20 is enabled, the DB Connection Service uses E1_0 to E3_32767 (NJ101-[][]20).
9. This number of axes is achieved in a combination of a CPU Unit with unit version 1.06 or later and Sysmac Studio version 1.07 or higher. In other combinations, the maximum number of controlled axes is 8 axes (NJ301-1200) or 4 axes (NJ301-1100).
10. Data is updated on the line in the specified interval regardless of the number of nodes.
11. The Packet interval of the CPU Unit version 1.02 or earlier is 10 to 10,000 ms in 1.0-ms increments.
12. Means packets per second, i.e., the number of communications packets that can be sent or received in one second.
13. The Permissible Communications Band of the CPU Unit version 1.02 or earlier is 1,000 pps.
14. An IGMP client is mounted for the EtherNet/IP port. If an ethernet switch that supports IGMP snooping is used, filtering of unnecessary multicast packets is performed.
15. The Maximum number of TCP socket service of the CPU Unit version 1.02 or earlier is 16.
16. Roles can be set for the unit versions 1.62 or later of CPU Units.
17. Ring topology is supported with the project version 1.40 or later of NJ[]01-[][]00. Slaves on a ring topology should support a ring topology. If Omron slaves, please see the user’s manual of slaves.
18. For project unit version earlier than 1.40, the data must be within four frames.
19. The Maximum Communications Cycle of the NJ301 CPU Unit version 1.02 or earlier and NJ501-R[][][] are 1,000/2,000/4,000 μs. The EtherCAT communications cycle of NJ501-4[][]0 for robot control is 1 ms or more.
Note: For robot control by NJ501-4[][]0, use the G5 series/1S series AC Servo Drive with built-in EtherCAT communications, absolute encoder, and brake.
