2.3 HEAT DISSIPATION
The heat dissipation values for the Ethernet board and Fast data server
are listed in the table below. For the heating values of the system unit
of the CNC or other option units, refer to the connection manual
supplied with the CNC.
Fast Ethernet board Fast data server
Board only 6 W 6 W (Note 1)
ATA flash card - 0.3 W (Note 2)
Total 6 W 6.3 W
NOTE
1 Some Fast data severs for stand-alone type control
units (Series16i/18i-A/B) have the RISC option
implemented on a printed circuit board. The
dissipation values shown above do not include that
for the RISC option. For details of the RISC option,
refer to the connection manual supplied with the
CNC.
2 The dissipation value of the ATA flash card may
vary, depending on whether a large-capacity card is
used or whether the card specification has been
modified.
