INSTALLATION
2.3 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 or Class 0x03 Instance 1 Attribute 1 to "63 (initial value)".
Set the arrow (×) of the corresponding switches to the number to set a desired address.
z 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.)
