Description
Unit power sup-
ply
This is the power supply for generating the NX Unit power supply required for the Slave Termi-
nal to operate.
This is connected to the Unit power supply terminal on the Communications Coupler Unit or on
the Additional NX Unit Power Supply Unit.
The internal power supply circuit in the Communications Coupler Unit or the Additional NX Unit
Power Supply Unit generates the NX Unit power supply from the Unit power supply.
The internal circuits of the Communications Coupler Unit and NX Units operate by the NX Unit
power supply.
The NX Unit power supply is supplied to the NX Units in the Slave Terminal through the NX bus
connectors.
I/O power sup-
ply
This power supply provides power to drive the I/O circuits of the Position Interface Units and it
provides power to external devices such as external encoders and sensors.
There are the following two I/O power supply methods. Either supply method used depends on
each model of NX Unit.
• Supply from the NX bus
• Supply from external source
Refer to
4-3-2 Supplying Each Power Supply and Wiring
on page 4-15 for the details on the
power supply methods.
