2.3 Node address switch setting
Set the node address between "H00" and "H7D" using the node address switches on the FR-A8NP board. (Refer to
.)
The setting is applied at the next power-ON.
Set the arrow (
) of the corresponding switches to a number or an alphabet to set a desired address.
• Setting example
NOTE
• 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 (alphabet) position correctly. If the switch is set between numbers,
normal data communication cannot be established.
• When the node address switches are set to any of H7E to HFF, the node address is recognized as H7D.
• The node addresses, H00, H01, H02, H7C, and H7D, may not be available for some master modules.
• You cannot set the same node address to other devices on the network. (Doing so disables proper communication.)
Node address 1:
Set the "
" of X16 (SW3) to "0" and the "
" of X1
(SW2) to "1".
Node address 38 (H26):
Set the "
" of X16 (SW3) to "2" and the "
" of X1
(SW2) to "6".
