• Up to 63 NX-IO Units can be connected to one EtherCAT Coupler Unit. Standard and high-performance units can be mixed.*1
• High-speed remote I/O control is possible at the fastest communication cycle of 125 us.*2
• Each Coupler plus its I/O form just a single EtherCAT node on the network.
• I/O control and safety control can be integrated by connecting Units for safety.
• The Coupler supports the EtherCAT Distributed Clock (DC) and propagates this to synchronous I/O units.
• The node address can be fixed by rotary switches, or set by software. Choose the method that best suits your way of engineering.
• Slave configuration by Sysmac Studio can be done centrally via the controller, or on-the-spot using the Coupler's built-in USB port.
*1 Input per Coupler Unit: Maximum 1024 bytes, Output per Coupler Unit: Maximum 1024 bytes

*1. Refer to the NX-series Safety Control Units User’s Manual (Cat. No. Z930) for the number of Safety Control Units that
can be connected.
*2. This function was added or improved for a version upgrade. Refer to the NX-series EtherCAT Coupler Unit User’s
Manual (Cat. No. W519) for information on version upgrades.
*3. The range of node addresses that can be set depends on the model of the built-in EtherCAT port. For the node address
ranges that can be set for a built-in EtherCAT port, refer to the user's manual for the built-in EtherCAT port on the
connected CPU Unit or Industrial PC.
*4. This depends on the specifications of the EtherCAT master. For example, the values are as follows when the EtherCAT
Coupler Unit is connected to the built-in EtherCAT port on an NJ5-series CPU Unit: 500 μs, 1,000 μs, 2,000 μs, and
4,000 μs. For the specifications of the built-in EtherCAT port, refer to the user's manual for the built-in EtherCAT port
on the connected CPU Unit or the Industrial PC.
*5. This depends on the Unit configuration.
*6. There are restrictions in the communications cycles that you can set for some of the NX Units. If you use any of those
NX Units, set a communications cycle that will satisfy the specifications for the refresh cycles that can be executed by
the NX Unit. Refer to the appendix of the NX-series Data Reference Manual (Cat. No. W525-E1-07 or later) to see if
there are restrictions on any specific NX Units. For information on the communications cycles that you can set, refer to
the user’s manuals for the NX Units.
*7. Refer to the NX-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519) for procedures for designing the Unit
power supply system and I/O power supply system.
*8. Use a voltage that is appropriate for the I/O circuits of the NX Units and the connected external devices.
