Node Address Setting
(1) Setting with node address switch
Set the node address between "1 to 127(7Fh)" using node address switches on the FR-A7NCA
(refer to
page 4).
The setting is reflected when power turns on next or the inverter is reset.
Set the node address switch to node address (SW1 setting
×
16 + SW2 setting).
Set
Pr.347 CANopen address
to "0 (initial value)".
Set the arrow (
×
) of the corresponding switches to the number to set a desired address.

Setting example
(2) Set with parameter
(Pr. 347)
Use parameter
(Pr. 347)
of the inverter to set. Setting node address with parameter makes the node
address switch setting invalid. The setting is reflected at the next power-on or inverter reset.
(Refer to
page 15)
Node address 1:
Set the "
×
" of SW1 to "0" and the "
×
" of
SW2 to "1".
Node address 127:
Set the "
×
" of SW1 to "7" and the "
×
" of
SW2 to "F".
CAUTION
1. 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.
2. When the node address switch is set to values other than "1 to 127", they are
regarded as "127".
