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.

Setting example

Node address 1:

Set the " " of X10(SW1) to "0" and the

" " of X1(SW2) to "1".

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.)

Node address 26:

Set the " " of X10(SW1) to "2" and the

" " of X1(SW2) to "6".
