Additional Information
Excess or insufficiency in the NX Unit power supply capacity can be easily checked when the
Unit configuration is created on the CPU and Expansion Racks Tab Page on the Sysmac Stu-
dio.
Use the following procedure to check the power supply capacity
.
On the CPU and Expansion Racks Tab Page on the Sysmac Studio, select the Unit to supply
NX Unit power. The power that is supplied by the NX Unit power supply (i.e., the total power
consumption) and the power supply capacity are displayed for the Supply Power/Available
Power parameter.
The following example is for when selecting the NX502 CPU Unit.
If the power to supply exceeds the NX Unit power supply capacity of the Unit that is selected to
supply the NX Unit power, a yellow warning icon is displayed by the first NX Unit for which there
is not suf
ficient capacity and also by all the remaining NX Units.
The Sysmac Studio does not consider the I/O power supply design conditions. When actually
designing the power supply
, refer to 4-3-2 Designing the I/O Power Supply from the NX Bus
on
page 4-15.
