1. Before you begin
Read and understand these instructions before performing any procedure with this drive.
DANGER
HAZARDOUS VOLTAGE
•Read and understand the Installation Manual before installing or operating the Altivar 71 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 boards, 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 present.
•DO NOT short across terminals PA and PC or across the DC bus capacitors.
•Install and close all the 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
DAMAGED EQUIPMENT
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 Modbus Plus communication card (catalog number VW3 A3 302) is used to connect an Altivar 71 drive to a Modbus Plus network.
The data exchanges permit full drive functionality:
•PeerCop control and adjustment
•Monitoring using the Global Data service
•Configuration, adjustment and diagnostics using the Modbus message handling service
If the Peer Cop service is not used for control, the drive can be controlled using the Modbus message handling service.
The card has a 9-way female SUB-D connector for connection to the Modbus Plus network.
The address of the drive is configured using the switches on the card.
The graphic display terminal on the drive can be used to access numerous functions for communication diagnostics.
The cable and accessories for connection to the Modbus Plus network must be ordered separately.
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 are displayed on the graphic display terminal in square brackets.
Example: [Fallback speed]
Parameter codes are displayed on the integrated 7-segment display terminal in round brackets.
Example: (LFF).

4. 4. Configuring the switches
The switches are used to configure the mode (normal or Altivar 58/58F migration) and the address on the network.
The correspondence between the drive and the position of the switch is as follows:
•0 = OFF = Switch in upper position
•1 = ON = Switch in lower position
The switch on the right-hand side is used to configure the Modbus Plus card mode:
•0 = OFF = normal mode
•1 = ON = Altivar 58/58F migration mode This manual only describes normal mode.
To find out about Altivar 58 migration mode, refer to the Altivar 58/58F Migration Manual.
The table below indicates the positions of the switches for all configurable addresses (1 to 64) in normal mode:
