 Equation in the Slave Terminal
<Equation>
The equation for the Unit power supply capacity in the Slave Terminal is as follows.
Unit power supply capacity in the Slave Terminal = The total power capacity from Unit power
supply on each block
The equation for the Unit power supply capacity on each block in the Slave Terminal is as follows.
Unit power supply capacity requirement for each block = ((A) + (B))/(C)
(A): The NX Unit power consumption of the Unit that supplies NX Unit power
(B): The total power consumption from the NX Unit power supply that is required by the NX Units that are connected to
the Unit that supplies NX Unit power
(C): The NX Unit power supply efficiency of the Unit that supplies NX Unit power
<Block>
The following shows the Unit that supplies NX Unit power and its supplying range. For example, the
Slave Terminal in the following diagram is configured with two blocks: the Communications Coupler
Unit block and the Additional NX Unit Power Supply Unit block.

The total Unit power supply capacity for these two blocks is the power supply capacity that the Slave
Terminal requires.
