The following CNC–related units require an input power supply that
satisfies the indicated current capacities with a power supply voltage of
24 VDC "10%. Here, note that momentary voltage changes and ripples
are also within "10% of the power supply voltage.

NOTE
1 The liquid–crystal display and MDI unit are included. Option
boards are not included.
2 For other peripheral units (such as I/O units), see Table
3.2.1 (b) and also refer to the relevant manuals.
3 When you select the input DC power supply for the CNC
control section, consider the restrictions other than the
power supply capacity. Be sure to see also Subsection
4.4.2.
4 When an RS–232–C device using power from NC is
connected to the RS–232–C port, the power capacity
increases by one ampere.
