3.2 POWER SUPPLY CAPACITY
3.2.1 Power Supply Capacities of CNC-related Units
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.

2 When an RS-232C unit (with power supplied from
the NC) is connected to the RS-232C port, +0.2 A
is further required.
3 Use memory cards that consume no more than 2
W.
4 For the PANEL i, see Chapter 13.
5 For the FS300i/310is/320is, see Chapter 11.
6 For other peripheral units (such as I/O units), see
Table 3.2.1 (b) and also refer to the relevant
manuals.
7 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.
