a cable on the inverter front cover as shown below. If a cable for LONWORKS communication is passed
through inside the inverter front cover, the bending radius of the cable becomes small, stressing the
cable.
CAUTION
When wiring, take care not to subject the cable to stress.
After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or

Parameter values written by
communication are written to the RAM.
⋅ When changing the parameter values frequently, set "1" in Pr. 342 to write them to the RAM.
Performing frequent parameter write with "0 (initial value)" (EEPROM write) set will shorten the life of the
EEPROM.
REMARKS
• When "1" (write to RAM only) is set in Pr. 342, powering off the inverter will erase the changed parameter values.
Therefore, the parameter values available when power is switched on again are the values stored in EEPROM

REMARKS
• For detection of communication error, set Pr. 391 Receive time interval at heart beat and set the send time interval from the
other node shorter than the heartbeat receive time interval.
When data is not received for more than the heartbeat receive time interval after the first reception, it is considered as a

• A communication line error [E.OP1 (alarm data: HA1)] is an error that occurs on the communication line,
and an error of the communication option unit itself [E. 1 (alarm data: HF1)] is a communication circuit error
in the option.
• The alarm output indicates alarm output signal (ALM signal) or alarm bit output.
• When the setting was made to provide an alarm output, the error definition is stored into the alarm history.
(The error definition is written to the alarm history when an alarm output is provided.)
When no alarm output is provided, the error definition overwrites the alarm indication of the alarm history
temporarily, but is not stored.
After the error is removed, the alarm indication is reset and returns to the ordinary monitor, and the alarm
history returns to the preceding alarm indication.
• When the Pr. 502 setting is "1" or "2", the deceleration time is the ordinary deceleration time setting (e.g. Pr.
8, Pr. 44, Pr. 45).
• The acceleration time at a restart is the ordinary acceleration time setting (e.g. Pr. 7, Pr. 44).
• When the Pr. 502 setting is "2", the operation/speed command at a restart is the one given before the error
occurrence.
• When a communication line error occurs at the Pr. 502 setting of "2", removing the error during deceleration
causes acceleration to restart at that point. (Acceleration is not restarted if the error is that of the option unit
itself.)

REMARKS
• The variable is initialized to "HFF" at power-on or if it is not updated at the "heartbeat receive time interval
(nciRcvHrtBt)" (Refer to page 97).
• The inverter operates at value = 100% frequency even if "the value exceeding 100%" is set when state = "H1".
• Updating nviDrvSpeedScale resets the start command depending on the state of nviDrvSpeedStpt.

Speed adjustment (0.005% increments) (network input
SNVT_lev_percent nviDrvSpeedScale)
You can set the set frequency in 0.005% increments on the assumption that the frequency set in "reference
frequency setting (nciNmiFreq)" (Refer to page 101) is 100%.
⋅ When the state of nviDrvSpeedStpt is H1, the motor is placed in forward rotation status if nviDrvSpeed
Scale value is positive and placed in reverse rotation status if the value is negative.
⋅ When state of nviDrvSpeedStpt is H0, the motor is at a stop status.

⋅ Data acceptance timing ........... At network variable receive (nv_update_occurs event)
The frequency to be written to the inverter actually is as shown in the following formula.
Set frequency = | (reference frequency setting × speed adjustment × simple speed setting)|
For example, when "Reference frequency setting (nciNmlFreq)" = 60.0Hz, "Speed adjustment
(nviDrvSpeedScale)" = -150%, and "Simple speed setting (nviDrvSpeed Stpt.value)" = 50%, output
frequency is (60.00Hz × ( -150%) × 50%) = -45Hz.
Therefore, a reverse command of 45Hz is given.
REMARKS
• The variable is initialized to "100.00%" at power-on or if it is not updated within the set "heartbeat receive time
interval (nciRcvHrtBt)" (Refer to page 97).
• Control can not be exercised at less than the minimum frequency resolution (0.01Hz) of the inverter.
• To make the change of "reference frequency setting (nciNmlFreq)" reflected to the operation speed, a value is need
to be written to speed adjustment (nviDrvSpeedScale)

Output frequency is as shown in the following formula.
Output frequency = | (reference frequency setting × speed monitor × simple speed setting) *|
* Refer to page 101 for reference frequency setting and page 48 for simple speed setting.
For example, when "reference frequency setting(nciNmIFreq)" = 60.0Hz, "speed setting
monitor(nvoDrvSpeed)" = -150%, and "simple speed setting(nviDrvSpeedStpt.value)" = 50%, output
frequency is (60.0Hz × (-150%) × 50%) = -45Hz.
Therefore, a reverse rotation of 45Hz is given.

REMARKS
• The send time interval of one network variable is time set in Pr. 388 (Pr. 389) independently of the number of
monitors bound by network management packages such as LonMaker.
For example, when the speed monitor and output current monitor are bound, the send time interval of the speed
monitor is Pr. 388 (Pr. 389)s and the send time interval of the output current monitor is also Pr. 388 (Pr. 389)s.
In addition, the actual send time interval is 1.1s due to constraints of each data send time even when Pr. 388 Send
time interval at heart beat is set to 1.0s or less. (It takes 1.2s when monitor data is set.)

REMARKS
• Control can not be exercised at less than the minimum frequency resolution (0.01Hz) of the inverter.
• The value stored in the inverter is rounded up. For example, 1.005% is rounded up to 1.010%.
• When the inverter operation status has changed, e.g. from a stop to startup or from running to a stop, the monitor
value is output even when the value is within the event driven detection width.
(Example) when the output frequency monitor and Pr. 392 Event driven detection width = "100%",
Pr. 390 % setting reference frequency = "60Hz" (set frequency)
As the monitor is output once at starting from the stop status, the starting monitor output is 0.5Hz when the
starting frequency is set to 0.5Hz. Therefore, the second monitor output is equal to or more than "0.5Hz+60Hz
(Pr. 390 setting × Pr. 392 setting)" = "60.5Hz". (This is not the monitor output when the frequency reaches 60Hz.
Use the SU signal to detect output frequency, etc.)

APPENDIX
Setup Example
The following is an example of procedure to perform
LONWORKS communication with the FR-A7NL.
(1) Confirmation of installation and connection
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)
(2) Parameter setting of the inverter
(when the network operation mode is always set)
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)
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
Power on the inverter (inverter reset) again to change the
mode to network operation mode.
(4) Perform LONWORKS communication
setting
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.
(5) Check the
variables
status
of
the
network
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".)
(6) Setup is completed
105
APPENDIX
Example of Inverter Parameter Clear
The following shows procedure to make
LONWORKS communication again when inverter
parameter clear is performed from LONWORKS
communication.
(1) Perform parameter clear
Perform parameter clear via network or with the operation
panel or parameter unit.
When performing with the operation panel or parameter
unit, the procedure is the same as that of the inverter.
When performing via the network (LONWORKS), use the
command request "SNVT_str_asc nviInvCmdReq" (Refer
to page 77) of network variables.
Data set by command request:
Request flag = H01
Request code = H00FC
Request data = H5A5A, H55AA
⋅ Parameter for communication is also cleared when
H9696 and H9966 are set as request data.
(Refer to page 77)
⋅ When Pr. 79 = "2", resetting is necessary as the set
value is cleared.
106
(2) Check the
variables
status
of
the
network
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".)
(3) LONWORKS communication resetting is
complete
