• 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.

• Set the node address switch to the switch number position correctly. If the switch
is set between numbers, normal data communication can not be established.
456
• If the node address switch is set to a value other than "1 to 64", it is invalid due to outside of setting
range. In this case, DEV LED of the option is lit red and E.OPT appears on the operation panel of the
inverter.
• You cannot set the same node address to other devices on the network. (Doing so disables proper
communication.)
• 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.
• Changes in the node address setting are applied only at the next power-ON. Therefore, if the node
address setting is changed, make sure to power OFF and ON the inverter power.

(2) Operation mode switching by the PU operation interlock signal (X12)
PU operation interlock is a function that forcefully changes the operation mode to the Network operation
mode at turn-OFF of the X12 signal (Bit 11), which gives operation commands through FL remote
communication.
This function prevents the operation mode from being accidentally unswitched from the PU operation
mode. If the operation mode left unswithced from the PU operation mode, the inverter does not reply to the
commands sent through FL remote communication.

CAUTION
• A communication line error [E.OP1 (fault data: HA1), E.OP2 (fault data:HA2), E.OP3 (fault data: HA3)] is an
error that occurs on the communication line, and an error of the communication option unit itself [E. 1 (fault
data: HF1), E. 2 (fault data:HF2), E. 3 (fault data: HF3)] is a communication circuit error in the option.
• The fault output indicates fault output signal (terminal ABC1) or fault bit output.
• When the setting was made to provide a fault output, the fault record is stored into the faults history. (The
fault record is written to the faults history when a fault output is provided.)
When no fault output is provided, the error record overwrites the fault indication of the faults history
temporarily, but is not stored.
After the error is removed, the fault record is reset and returns to the ordinary monitor, and the faults
history returns to the preceding fault indication.

Frequency and speed conversion specifications
When setting or monitoring a frequency through the FR-A7NF, the frequency is set or monitored in 0.01Hz
increments regardless of the Pr. 37 Speed display setting. When setting or monitoring a speed through the
FR-A7NF, the speed is calculated with Pr.144 Speed setting switchover as shown below.
Speed setting, monitoring (1r/min increments) = 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.

FL REMOTE COMMUNICATION FUNCTION
5.2
Types of data communication
FL remote data communication supports "cyclic transmission" which transmits data periodically (refer to
page 41) and "message transmission" which transmits data non-periodically (refer to page 58).

CYCLIC TRANSMISSION
Cyclic transmission transmits data periodically. Each node shares data through common memory. (Refer to
page 42 for common memory. )
Data of I/O area is updated periodically by cyclic transmission.
The master controls the inverter by setting run command (control input command, set frequency, etc.) in
the output data area.
The inverter sets the inverter status (output frequency, output current, various signals, etc.) in the input
data area and sends it to the master.

CYCLIC TRANSMISSION
6.1
Common memory
Concept of common memory is stated below.
(1) The common memory is used as a shared memory between nodes which perform cyclic transmission.
(2) The common memory has two areas which are "common memory area 1" and "common memory area
2".
Common memory area 1 is I/O data area. Common memory area 2 is the control information area.
Two different areas can be assigned to each node.
(3) When the area each node sends exceed the transmission size (1024 byte) by one frame, data is
transmitted by multiple frames.
(4) When receiving data which are divided into multiple frames as (3), common memory is not updated until
all frames sent from one node are received. Synchronism per node unit is guaranteed.
(5) Entire network has an area of 8k bit (0.5k word) + 8k word = 8.5k word.
The maximum send data capacity per one node is 8.5k word. (Note that one word is 2 byte.)

CYCLIC TRANSMISSION
(6) Among common memory, both common memory area 1 and common memory 2 can be set as a
transmission area of one node as desired within the maximum area.
(7) Each node on FL remote network can share the same data in the whole system by broadcasting data
at a constant period. In addition, each node has own transmission area which does not overlap each
other to exchange data. (For common memory function, the transmission area assigned to one node
is a receive area for other nodes.)

MESSAGE TRANSMISSON
Message transmission is a non-periodic data communication method to communicate to a specified node
when send request is given.
Basic function of message transmission is as follows.
(1) When a node receives a token, one frame can be sent before sending cyclic frame.
(2) The message frame size which can be sent at a time is 1024 byte maximum.
Message frame
1024 byte
(3) This method applies algorithm which controls refresh time not exceeding refresh cycle permissible
time.
(4) Two transmission functions are available. One is "one-to-one message transmission" to send to
specified nodes, and another is "one-to-n message transmission" to send to all nodes.
