APPENDIX
Setup Example
The following is an example of procedure to perform
LONWORKS communication with the FR-A7NL.
1) Check that the FR-A7NL is mounted on the option
connector of the inverter. (Refer to page 7)
2) Check that the twisted pair cable is connected to
NET_A and NET_B of the terminal block supplied
securely. (Refer to page 15)
3) Check that the terminating resistor is connected with a
LONWOKRS cable. (Please fabricate a terminating
resistor.) (Refer to page 13)
1) Set "0" (simple mode+extended parameters display) in
Pr. 160 User group read selection.
2) Set a value other than "0" in Pr. 340 Communication
startup mode selection. (Refer to page 21)
3) Set "0 or 2" in Pr. 79 Operation mode selection.
(Refer to page 21)
Power on the inverter (inverter reset) again to change the
mode to network operation mode.
Perform LONWORKS communication setting with
software necessary for LONWORKS communication
such as "LonMaker for Windows, Visio 2000". (For a
setting method, refer to the manual of software used.)
Communication setting is complete if "SERVICE" LED of
the FR-A7NL is not flickering.
1) Power on the inverter (inverter reset) again and reflect
the current network variables of the inverter to
LonMaker Browser.
2) Set LonMaker Browser to "Monitor All On" to turn on
monitoring of the inverter network variables.
(When "Monitor All Off" is set, only the initial value of
network variables the inverter sent to LonMaker
Browser can be referred. To always check network
variables, set "Monitor All On".)
(1) Confirmation of installation and connection
(2) Parameter setting of the inverter
(when the network operation mode is always set)
REMARKS
• By making parameter setting of 2) and 3) above, the
inverter operates in network operation mode when
the inverter power is switched on. (It is not necessary
to change the operation mode with network
variables.)
(3) Switch on the inverter power from off
(4) Perform LONWORKS communication
setting
(5) Check the status of the network
variables
(6) Setup is completed
