Node Address Setting
(1) Setting with node address switch
Set the node address between "0 to 63" using node address switches on the FR-A7ND
(refer to page 3).
The setting is reflected when power turns on next or the inverter is reset.
Set
Pr. 345

Setting example
Node address 1:
Set the "
×
" of X10(SW1) to "0" and the
"
×
" of X1(SW2) to "1".
Node address 26:
Set the "
×
" of X10(SW1) to "2" and the
"

" of X1(SW2) to "6".
CAUTION
• Set the inverter node address before switching on the inverter and do not change
the setting while power is on. Otherwise you may get an electric shock.
• Set the node address switch to the switch number position correctly. If the switch
is set between numbers, normal data communication can not be made.
• When the node address switch is set to values other than "0 to 63", they are regarded as "63".
• You cannot set the same node address to other devices on the network. (If different devices have the
same node address, the communication cannot be established properly.)
