SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
• While power is ON or when the inverter is running, do not
open the front cover. You may get an electric shock.
• Do not run the inverter with the front cover or wiring cover
removed. Otherwise, you may accidentally touch the exposed
high-voltage terminals and charging part and get an electric
shock.
• Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may accidentally touch the
charged inverter circuits and get an electric shock.
• Before wiring or inspection, power must be switched OFF. To
confirm that, LED indication of the operation panel must be
checked. (It must be OFF.) Any person who is involved in
wiring or inspection shall wait for at least 10 minutes after the
power supply has been switched OFF and check that there
are no residual voltage using a tester or the like. The
capacitor is charged with high voltage for some time after
power OFF, and it is dangerous.
• Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
• The plug-in option must be installed before wiring. Otherwise,
you may get an electric shock or be injured.
• Do not touch the plug-in option or handle the cables with wet
hands. Otherwise you may get an electric shock.
• Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an electric
shock.

2. Injury Prevention
3) Usage
WARNING
CAUTION
• The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst, damage,
etc. may occur.
• The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
• Polarity must be correct. Otherwise burst, damage, etc. may
occur.
• While power is ON or for some time after power-OFF, do not
touch the inverter as they will be extremely hot. Doing so can
cause burns.
3. Additional Instructions
Also the following points must be noted to prevent an accidental
failure, injury, electric shock, etc.
• Do not modify the equipment.
• Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the inverter.
CAUTION
• When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting operations
because all parameters return to the initial value.
• Static electricity in your body must be discharged before you
touch the product. Otherwise the product may be damaged.
4) Maintenance, inspection and parts replacement
1) Transportation and mounting
CAUTION
• Do not install or operate the plug-in option if it is damaged or
has parts missing.
• Do not stand or rest heavy objects on the product.
• The mounting orientation must be correct.

(1) Strip off the sheath of the cable for LONWORKS communication. If the length of the sheath peeled is
too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come
off.
Use the recommended cables. (Refer to page 6)
Wire the stripped cable after twisting it to prevent it from becoming loose.
(Do not solder it.)

⋅ Communication line error [E.OP1 (fault data: HA1), E.OP2 (fault data: HA2) and E.OP3 (fault data: HA3)] are
errors that occur on the communication line. Communication option error [E. 1 (fault data: HF1), E. 2 (fault
data: HF2) and E. 3 (fault data: HF3)] are errors that occur in the communication circuit inside the option.
⋅ Fault output indicates the fault output signal (ALM signal) and fault bit output.
⋅ When the fault output setting is active, fault records are stored in the faults history.
When the fault output setting is not active, fault record is overwritten to the faults history temporarily but
not stored.
After the error is removed, the fault indication is reset, changing the display back to normal, and the last
fault is displayed in the faults history.
⋅ 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.)

Frequency and speed settings
Frequency setting, monitoring, and parameter setting via FR-A7NL are always performed in 0.01Hz
increments regardless of the Pr. 37 Speed display setting.
The set speed and monitored values via FR-A7NL are converted to rotations per minute according to the
Pr. 144 Speed setting switchover setting as shown below.
Speed or monitored value (1r/min) = frequency × 120/number of motor poles (Pr.144*)
∗ When Pr. 144 = "102 to 110," the formula is calculated with the value of (Pr.144 - 100). When Pr. 144 = "0", the formula is calculated
with 4 poles.
REMARKS
⋅ Refer to the Instruction Manual of the inverter for the details of Pr.37 and Pr.144.

FUNCTION OVERVIEW
5.1 XIF file
Using the configuration software, network setting is easily done.
To use the configuration software, an XIF file is necessary. XIF file is used to recognize device features and
functions. For details of installation and XIF file usage, refer to the configuration software manual.
XIF file can be downloaded from
Mitsubishi Electric FA Network Service MELFANS web
http://www.MitsubishiElectric.co.jp/melfansweb or obtained from your sales representative.
CAUTION
⋅ Check the manufactured date of your FR-A7NL, and use the appropriate XIF file. (For how to find the SERIAL
number (manufactured date), refer to page 2.) An incorrect XIF file will disrupt normal operation. For details, refer to
MELFANS web or contact your sales representative.
⋅ Since memory for write enable application is not installed in the inverter, Mitsubishi does not provide application files
(file extensions such as .nxe, .apb).

You can set "start/stop" and "simple setting of set frequency".
⋅ Set start/stop in state.
The rotation direction (forward/reverse rotation) is determined by whether "speed adjustment
(nviDrvSpeedScale)" is positive or negative. (Refer to page 50)
⋅ Set simple speed setting in value.
As the set frequency, set its ratio to "speed adjustment (nviDrvSpeedScale)" (0.5% increments).

You can set the set frequency in 0.005% increments on the assumption that the frequency set in "reference
frequency setting (nciNmiFreq) is 100%. (Refer to page 107)
⋅ 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.

⋅ 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) |
Example:
When "Simple speed setting (nviDrvSpeed Stpt.value)" = 50%, "Reference frequency setting (nciNmlFreq)"
= 60.0Hz, and "Speed adjustment (nviDrvSpeedScale)" = -150%, 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 103)
⋅ 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 107 for reference frequency setting and page 49 for simple speed setting.
Example:
When "reference frequency setting (nciNmIFreq)" = 60.0Hz and "speed setting monitor (nvoDrvSpeed)" =
-150%, "simple speed setting (nviDrvSpeedStpt.value)" = 50%, output frequency is (60.0Hz × (-150%) ×

Therefore, a reverse rotation of 45Hz is given.

REMARKS
⋅ The Pr. 388 (Pr. 389) setting determines the time interval between a network variable transmissions. The number of
monitors selected by a network administration tool, such as LonMaker, does not affect the time interval.
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 the Pr. 388
Send time interval at heart beat is set to 1.0s or less. (It takes 1.2s when monitor data is set.)

⋅ Control cannot be executed 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 output frequency monitor = "100%", Pr. 392 Event driven detection width = "100%",
and Pr. 390 % setting reference frequency = "60Hz" (set frequency)
As the monitor is output once when 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 9)
2) Check that the twisted pair cable is connected to
NET_A and NET_B of the terminal block supplied
securely. (Refer to page 12)
3) Check that the terminating resistor is connected with a
LONWOKRS cable. (Please fabricate a terminating
resistor.) (Refer to page 11)
(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 19)
3) Set "0 or 2" in Pr. 79 Operation mode selection.
(Refer to page 19)
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
setting
LONWORKS communication
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 status of the network variables
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".)

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 79) 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 83)
⋅ When Pr. 79 = "2", resetting is necessary as the set
value is cleared.
