(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 card.
(Figure 3.3)

Check that the positioning cutout (shown in Figure 2.1) 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 to the communications card.

For details, refer to Chapter 4 "WIRING AND

CABLING."

(4) Put the front cover back into place.

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 an accident.

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.

Chapter 6 ESTABLISHING A T-Link COMMUNICATIONS LINK

6.1 Starting Procedure

After confirming that wiring to the T-Link has been completed, establish a T-Link communications link between
the MICREX and the inverter and start T-Link communication, using the procedure given in this chapter.

T-Link communication enables the MICREX to issue run commands and monitor the inverter's operation.

For details, refer to Chapter 7 "COMMUNICATIONS FORMAT."

(1) Configure the MICREX.

- Set a station address of the T-Link communications card (e.g., 00) using the MICREX loader. The relay
area should not be double assigned by any other T-Link station address.

- Allocate read and write areas on the T-Link communications card. Each of those areas is 4 words in

length, regardless of the format.

- In the I/O group setting, register the T-Link communications card as both input and output devices.

For details about the relay area to be occupied, refer to Chapter 6, Section 6.2 "I/O Relay Area

Occupied."

For details about configuring MICREX, refer to the MICREX user's manual.

(2) Configure the station address switches (RSW1 and RSW2) on the communications card. (Refer to Section

2.2.)

- Before accessing the station address switches, make sure that both the inverter power and the T-Link
communications card power are turned OFF.

- Set the station address switches to the station address that matches the one specified by the loader.

(3) Turn the inverter power ON and configure the inverter's function codes.

- Select the communications format with the inverter's function code o30.

- Configure the inverter's function codes o27, o28, and y98, if necessary.

For details about the communications format, refer to Chapter 7 "COMMUNICATIONS FORMAT."

(4) Power ON the MICREX and send a T-Link connection request to the inverter.

For details about how to send a connection request from the MICREX, refer to the MICREX user's

manual.

(5) Start I/O data exchange.
In response to the connection request from the MICREX, the T-Link communications link will be established

if the MICREX and the T-Link communications card have been properly configured and wiring between
them is correct.

The MICREX exchanges data with the inverter in accordance with the communications format selected,

making it possible to control the inverter.

When the error LED on the MICREX T-Link module is ON, no T-Link communication is possible.

13

6.2 I/O Relay Area Occupied

T-Link communication uses a consecutive eight-word area per inverter in the I/O relay area as shown below.
The two-digit address (** in WB00**) should be configured with rotary switches RSW1 and RSW2 on the
communications card.
