1.3 Node Address Setting
•Setting with node address switch
Set the node address between "0Hto 7DH" using node address switches on the FR-A7NP (refer to page 4).
The setting is reflected at the next power-on or inverter reset.
Set the arrow (×) of the corresponding switches to the number and alphabet to set a desired address.
•Setting example
Node address 1:
Set the "×" of x16(SW3) to "0" and the
"×" of x1(SW1) to "1".
Node address 26:
Set the " ×" of x16(SW3) to "2" and the
"×" of x1(SW1) to "1".
CAUTION
1. Set the node address switch to the switch number (alphabet) position correctly.
If the switch is set between numbers, normal data communication can not be
made.
2. Do not set the node address to 7EHthrough FFH.
3. Depending on the master module, 0H, 1H, 2H, 7CH, 7DHof node address may not
be used.
4. You cannot set the same node address to other devices on the network. (Doing so disables proper
communication.)
5. 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.

WIRING
REMARKS
⋅When the hook of the inverter front cover is cut off for wiring, the protective structure (JEM1030) changes to open
type (IP00).
When performing wiring using the space between the inverter front cover and control circuit
terminal block, take care not to subject the cable to stress.
After wiring, wire offcuts must not be left in the inverter. They may cause an error, failure or
malfunction.
