SAFETY INSTRUCTIONS
•
••
•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 removed. Otherwise, you may
access the exposed high-voltage terminals and charging part and get an
electric shock.
•
••
•If power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric
shock.
•
••
•Before starting wiring or inspection, switch power off, wait for more than 10
minutes, and check for no residual voltage with a tester or the like.
•
••
•Any person who is involved in the wiring or inspection of this equipment
should be fully competent to do the work.
•
••
•Always install the option unit before wiring. Otherwise, you may get an
electric shock or be injured.
•
••
•Handle this option unit with dry hands to prevent an electric shock.
•
••
•Do not subject the cables to scratches, excessive stress, heavy loads or
pinching. Otherwise, you may get an electric shock.
•
••
•While power is on, do not move the station number and baud rate setting
switches. Doing so can cause an electric shock.

•
••
•Before starting operation, confirm and adjust the parameters. A failure to do
so may cause some machines to make unexpected motions.
•
••
•Do not modify the equipment.
•
••
•When parameter clear or all parameter clear is performed, each parameter
returns to the factory setting. Re-set the required parameters before starting
operation.
•
••
•For prevention of damage due to static electricity, touch nearby metal before
touching this product to eliminate static electricity from your body.
•
••
•Do not test the equipment with a megger (measure insulation resistance).
•
••
•Treat as industrial waste.

1.1 Unpacking and Product Confirmation
Take the option unit out of the package, check the unit name, and confirm
that the product is as you ordered and intact.
Note that the FR-A500/F500 series inverter and FR-V500 series inverter
have different functions when the option is fitted.
Please check the SERIAL number of the inverter when using the FR-V500
series.
•SERIAL number check
•This product maybe used with the FR-V500series manufactured in and
after May 2002. Any of the models may be used with this unit if its
SERIAL number indicated on the rating plate and package has
"!25!!!!!!" or later version. For details on the SERIAL number,
please contact your sales representative.
SERIAL is made up of 1 version symbol, 1 alphabet letter or numeric
character indicating month, and 7 numeric characters indicating year

2. INSTALLATION
2.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
2.2 Inverter Node Address Setting
Set the node address of the inverter on the Profibus network.
Set the inverter node address before switching on the inverter and do not
change the setting while power is on.
The node address may be set between 0Hand 7DH.
With input power on, do not install or remove the option unit.
Otherwise, the inverter and option unit may be damaged.
CAUTION
1. Do not set the node address to 7EHthrough FFH.
2. Depending on the master module, 0H, 1H, 2H, 7CH, 7DHmay not
be used.
3. The node address changed while powering on the inverter is not
made valid. The node address setting is made valid either after
power is reapplied or when the RES signal turns on.
4. You cannot set the same node address to other devices on the
network. (Such setting disables normal communication.)
$Set the arrow (%) of the corresponding switch to the
required numeral.
Example:
•For node address 1H:
Set (%) of SW1 to "0" and (%) of SW2 to "1".
•For node address 7DH:
Set (%) SW1 to "7" and the (%) SW2 to "D".
REMARKS
Set each node address switch to the
position of its numeral without error. If it is
set to any position between numerals,
normal data communication cannot be
made.

2.3 Installation and Removal Procedure
Mount the option unit to slot 3.
(1) Remove the front cover from the inverter and remove the DATA PORT
cover by pushing it from the back of the front cover.
(2) Securely insert the connector of the option unit far into the connector
of slot 3 in the inverter. At this time, fit the option fixing holes snugly.
For the position of slot 3, refer to the illustration below.
Also be sure tofit the unit into the option fixing hook (For the FR-A500/
FR-F500 series, it is available in Aug., 2000).
(3) Securely fix the option unit to the inverter on both sides with the
accessory mounting screws. If the screw holes do not line up, the
connector may not have been plugged snugly. Check for loose
plugging.
(4) Reinstall the front cover of the inverter. (Refer to the inverter manual.)
(5) Connect a Profibus communication cable to the Profibus connector
(Dsub9 pin connector) of the option. (Refer to page 7 for a
communication cable.)

REMARKS
Perform wiring after the option unit (FR-A5NPA) was fitted and the inverter front
cover was mounted.
The option unit (FR-A5NPA) is valid only if it is fitted in slot 3.
When two or more communication option units are mounted, "E.OPT" error is
displayed. Note that when the relay output/computer link unit (FR-A5NR) is
mounted, only relay output is activated.

3.2 Operation Mode
The inverter mounted with the option unit (FR-A5NPA) has the following
operation modes:
(1) PU operation [PU] .................Controls the inverter from the keyboard
of the operation panel (FR-DU04(-1)) or
parameter unit (FR-PU04(V)) (referred
to as the "PU") installed to the inverter.
(2) External operation [EXT] .......Controls the inverter by switching on/off
external signals connected to the
control circuit terminals of the inverter.
(3) Network operation [NET].......Controls the inverter with instructions
from the Profibus master module via the
option unit (FR-A5NPA).
(The operation signal and running
frequency can be entered from the
control circuit terminals depending on
the Pr.338 "operation control command
source" and Pr. 339 "speed command
source" setting.)

REMARKS
1. The Pr. 340 value may be changed from the PU in any operation mode.
2. Computer programming, which has stopped due to an instantaneous power
failure or like during network operation, remains stopped even if power is
recovered.
3. When Pr. 340 = "2":
When a start command is given from the network with restart enabled (Pr. 57
≠9999), a start command during power off (including instantaneous power
failure and power failure) is stored. Therefore, the inverter resumes operation
in the state before powering off at powering on again (power restoration).
