Node Address Setting - Mitsubishi Electric FR-A7ND Instruction Manual

2.4

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 2).
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 ×10(SW1) to "0" and the
" " of ×1(SW2) to "1".
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 "0 to 63", they are
regarded as "63".
(2) Set with parameter (Pr. 345)
Use parameter (Pr. 345) 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)
(3) Setting with master
Use Class 0x03 Instance 1 Attribute 1 to set from the master. The setting change is reflected to Pr. 345.
Setting node address from the master makes the node address switch setting invalid. (Refer to page 39)
All connections are released and a set value is immediately reflected.
Node address 26:
0 0
Set the " " of ×10(SW1) to "2" and the
" " of ×1(SW2) to "6".
