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 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 meter etc.
!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.
!Operate the switches 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.
2. Injury Prevention
CAUTION
!Apply only the voltage specified in the instruction manual to each terminal to prevent damage, etc.
!Ensure that the cables are connected to the correct terminals. Otherwise, damage, etc. may occur.
!Always make sure that polarity is correct to prevent damage, etc.
!While power is on or for some time after power-off, do not touch the inverter as it is hot and you may get burnt.

!Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make
unexpected motions.
(3) Usage
WARNING
!Do not modify the equipment.

A - 4
CAUTION
!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.
(4) Maintenance, inspection and parts replacement
CAUTION
!Do not test the equipment with a megger (measure insulation resistance).
(5) Disposal
CAUTION
!Dispose of this product as general industrial waste.
(6) General instruction
All illustrations given in this manual may have been drawn with covers or safety guards removed to provide in-depth
description. Before starting operation of the product, always return the covers and guards into original positions as
specified and operate the equipment in accordance with the manual.

(1) Remove the front cover and option wiring port cover. (Refer to the inverter manual.)
(2) Remove the sponge from the inboard option connector, align the option unit connector with the inboard option connector
of the inverter, and securely insert it far enough into the inverter.
(3) Securely fix the top and bottom of the option unit to the inverter with the accessory mounting screws. If the screw holes do
not match, check for insecure connector insertion. The connector may not have been inserted securely.
(4) Reinstall the front cover to the inverter. (Refer to the inverter manual.)
Note:1. While the inboard option is plugged in, store the option wiring port cover carefully.
2. When this option is plugged in, the protective structure of the inverter is the open type (IP00).
3. If the inverter cannot recognize the plugged-in option, the E.OPT error appears. (Refer to the inverter manual.)

2.4 System Configuration Example
(1) PLC side
Load the "AJ61BT11", "A1SJ61BT11", "AJ61QBT11" or "A1SJ61QBT11" "Control & Communication Link system
master/local module" on the main or extension base unit having the PLC CPU used as the master station.
(2) Inverter side
Mount the "CC-Link unit (FR-E5NC)" on the inverter.
(3) Connect the PLC CC-Link unit master station and the FR-E5NC with the CC-Link dedicated cable.
If the cable used is other than the CC-Link dedicated cable, the performance of the CC-Link system is not guaranteed.
For the specifications and availability of the CC-Link dedicated cable, refer to the CC-Link catalog L (NA) -74108143E.

(4) When the CPU has automatic refresh function (example: QnA series CPU)
Through communication with the corresponding devices using sequence ladder logic, data is automatically transferred to
the refresh buffer of the master station at the execution of the END instruction to perform communication with the remote
devices.
(5) When the CPU does not have automatic refresh function (example: AnA series CPU)
Data is transferred to the refresh buffer of the master station directly by sequence ladder logic to perform communication
with the remote devices.

3.1 Pre-Operation Setting
3.1.1 Inverter station number setting
Set the inverter station number before switching on the inverter and do not change the setting while power is on.
When setting the station number, the following points should be taken into consideration:
1) The station number may be set between 1 and 64.
Fully note that if the station number is changed during operation, data communication cannot be made with the new
station number.
2) Setting method
zSet the arrow (×) of the corresponding switch to the required numeral.
Example:
yFor station number 1: Set (×) of ×10 to "0" and (×) of ×1 to "1".
yFor station number 26: Set (×) ×10 to "2" and (×) ×1 to "6".

(If the same station number is repeated, proper communication cannot be made.)
zSet each station number switch to the position of its numeral without error. If it is set to any
position between numerals, normal data communication cannot be made.

3.2 Operation Modes of the Inverter
The inverter mounted with the CC-Link unit (FR-E5NC) has the following operation modes:
(1) PU operation mode............... Controls the inverter from the keyboard of the operation panel (FR-PA02-02) or parameter
unit (FR-PU04) installed to the inverter.
(2) External operation mode....... Controls the inverter by switching on/off external signals connected to the control circuit
terminals of the inverter.
(3) CC-Link operation mode....... Controls the inverter in accordance with the PLC program via the CC-Link unit (FR-E5NC).
3.2.1 Operation mode switching
(1) Operation mode switching conditions
Before switching the operation mode, check that:
1) The inverter is at a stop;
2) Both the forward and reverse rotation signals are off; and
3) The Pr. 79 "operation mode" setting is correct.
(For setting, use the inverter's operation panel or optional parameter unit.)
Pr. 79 Setting Operation Mode Selection Switching to CC-Link Operation Mode
0 PU or external operation Disallowed when the PU mode is selected. Allowed when the
external mode is selected.
1 PU operation mode Disallowed
2 External operation mode Allowed
3, 4 External/PU combined operation mode Disallowed
6 Switch-over Allowed
7 External operation (PU operation interlock) Allowed only in the external operation mode when the output shut-
off signal (MRS) is off.
8 PU or external (signal switching) Allowed only in the external operation mode (X16 on).
