Chapter 3 INSTALLATION AND REMOVAL OF THE CC-Link COMMUNICATIONS

CARD

Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters with a
capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or above. Make
sure that the LED monitor and charging lamp are turned OFF. Further, make sure, using a multimeter or a
similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the
safe level (+25 VDC or below).

Otherwise, electric shock could occur.

• Do not use the products that are damaged or lacking parts.

Doing so could cause a fire, accident, or injury.

• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter and the communications card.

Otherwise, a fire or an accident might result.

• Incorrect handling in installation/removal jobs could cause a failure.

A failure might result.

Before mounting the communications card, perform the wiring for the main circuit terminals and control
circuit terminals.

3.1 Installing the Communications Card

(1) Remove the front cover from the inverter and expose the control printed circuit board (control PCB). As

shown in Figure 3.1, the communications card can be connected to the A-port only, out of three option
connection ports (A-, B-, and C-ports) on the control PCB.

To remove the front cover, refer to the FRENIC-MEGA Instruction Manual, Chapter 2, Section 2.3. For
inverters with a capacity of 30 kW or above, open also the keypad enclosure.

(2) Insert connector CN1 on the back of the communications card (Figure 1.1) into the A-port (CN4) on the

inverter's control PCB. Then secure the communications card with the two screws that come with the
communications card. (Figure 3.3)

Check that the positioning cutout (shown in Figure 1.1) is fitted on the tab ( in Figure 3.2) and
connector CN1 is fully inserted ( in Figure 3.2). Figure 3.3 shows the communications card
correctly mounted.

(3) Perform wiring on the communications card.

Refer to Chapter 4 "WIRING AND CABLING."

(4) Put the front cover back into place.

To put back the front cover, refer to the
FRENIC-MEGA Instruction Manual, Chapter 2,
Section 2.3. For inverters with a capacity of 30 kW or
above, close also the keypad enclosure.

Chapter 4 WIRING AND CABLING

• Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters with
a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or above.
Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure, using a
multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has
dropped to the safe level (+25 VDC or below).

• Qualified electricians should carry out wiring.

Otherwise, an electric shock could occur.

• In general, the covers of the control signal wires are not specifically designed to withstand a high voltage
(i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with
a live conductor of the main circuit, the insulation of the cover might break down, which would expose the
signal wire to a high voltage of the main circuit. Make sure that the control signal wires will not come into
contact with live conductors of the main circuit.

Failure to observe this precaution could cause an electric shock or fire.

Noise may be emitted from the inverter, motor and wires. Take appropriate measures to prevent the nearby
sensors and devices from malfunctioning due to such noise.

An accident could occur.

4.2 Wiring for CC-Link Terminal Block

(1) To connect this communications card to a CC-Link network, use a CC-Link dedicated cable complying with

the CC-Link specifications. Using a cable other than a CC-Link dedicated cable does not assure the
CC-Link system performance. Also observe the wiring lengths specified in the CC-Link version 1.10
specifications.

The recommended CC-Link cable is FANC-110SBH made by Kuramo Electric Co., Ltd.

For details about wiring for CC-Link, refer to the CC-Link Master Use's Manual or CC-Link Cable Wiring

Manual published by the CC-Link Partner Association. The CC-Link Cable Wiring Manual is available as a
free download from the CC-Link Partner Association's website at:
http://www.cc-link.org/eng/t_html/siryo.html

(2) Wiring around the CC-Link terminal block
The terminal block uses a pluggable 5-pin connector as shown in Figure 4.2. Table 4.1 shows the

correspondence between the pin numbers and the ID colors.

A typical connector that matches this terminal block is Phoenix Contact MCVW 1.5/5-STF-3.5.

Chapter 9 LIST OF INVERTER ALARM CODES

Through CC-Link, the master can monitor the information on alarms (in Table 9.1) that have occurred in the
inverter, by using the following procedure.

(1) Specify which alarm code--latest, last, 2nd last, or 3rd last--should be read out, into the remote register

RWw8. (The alarm code will be stored in RWr8.)

(2) Specify command codes 0074H and 0075H (in remote registers RWw2, 10, 12, 14, 16, or 18) to read out

alarm codes.

(3) Use inverter's communication dedicated function codes M16 to M19 to read out the latest, last, 2nd last, and

3rd last alarm codes, respectively.
