1. Before you begin

Read and understand these instructions before performing any procedure with thi s drive.

DANGER

HAZARDOUS VOLTAGE

• Read and understand the Installation Manual before installing or operating the ATV71 drive. Installation, adjustment,
repair, and maintenance must be performed by qualified personnel.

• The user is responsible for compliance with all international and national electrical standards in force concerning
protective grounding of all equipment.

• Many parts of this variable speed drive, including the printed circuit board s, operate at the line voltage. DO NOT TOUCH.
Use only electrically insulated tools.

• DO NOT touch unshielded components or terminal strip screw connections with voltage prese nt.

• DO NOT short across terminals PA/+ and PC/- or across the DC bus capacitors.

• Install and close all covers before applying power or starting and stopping the drive.

• Before servicing the variable speed drive

- Disconnect all power.

- Place a “DO NOT TURN ON” label on the variable speed drive disconnect.

- Lock the disconnect in the open position.

• Disconnect all power including external control power that may be present before servicing the drive.
WAIT 15 MINUTES to allow the DC bus capacitors to discharge. Then follow the DC bus voltage measurement
procedure given in the Installation Manual to verify that the DC voltage is less than 45 VDC. The drive LEDs are not
accurate indicators of the absence of DC bus voltage.

Electric shock will result in death or serious injury.

CAUTION

EQUIPMENT DAMAGE

Do not install or operate any drive that appears damaged.

Failure to follow this instruction can result in equipment damage.

3. Introduction

3. 1. Presentation

The communication card (catalog number VW3 A3 303) is used to connect an Altivar 71 drive to a Uni-Telway or Modbus bus.
This manual only describes how to connect and use the Altivar 71 with a Uni-Telway bus.
The exchanges possible:

• Control

• Monitoring

• Adjustment

• Diagnostics

• Downloading of configuration and adjustment parameters
The card has a 9-way female SUB-D connector for connection to the Uni-Telway bus.
The cables and Uni-Telway bus connection accessories should be ordered separately.
The drive address is configured using the switches on the card.
The graphic display terminal or the integrated display terminal can be used to access numerous functions for communication diagnostics.

3. 2. Notation

Drive terminal displays

The graphic display terminal menus are shown in square brackets.
Example: [1.9 COMMUNICATION]

The integrated 7-segment display terminal menus are shown in round brackets.
Example: (COM-)

Parameter names displayed on the graphic display terminal are shown in square brackets.
Example: [Fallback speed]

Parameter codes displayed on the integrated 7-segment display terminal are shown in round brackets.
Example: (LFF)

Formats

Hexadecimal values are written as follows: 16#
Binary values are written as follows: 2#

4. 1. Receipt

Check that the card catalog number marked on the label is the same as that on the delivery note corresponding to the purchase order.
Remove the option card from its packaging and check that it has not been damaged in transit.

4. 2. Hardware description

4. 3. Installing the card in the drive

See the Installation Manual.

4. Hardware setup

Address 11 = 2#0000 1011

Address 34 = 2#0010 0010

4. 4. Switch coding

b Choosing polarization

Set both switches to the lower position.

Polarization of the RS 485 line at 4.7 kΩ.

b Coding the address

The switches are used to encode the address (1 to 127) of the drive on the bus.
The switch settings can only be changed when the drive is turned off.
The correspondence between the value and the position of the switch is as follows:

• 0 = OFF = Switch in upper position

• 1 = ON = Switch in lower position
The address is binary-coded.
