Important Information
The addition of this symbol to a Danger or Warning safety label indicates that an electrical hazard exists, which will result in
personal injury if the instructions are not followed.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow
this symbol to avoid possible injury or death.
NOTICE
Read these instructions carefully, and look at the equipment to become familiar with the device before trying to install, operate, or maintain
it. The following special messages may appear throughout this documentation or on the equipment to warn of potential hazards or to call
attention to information that clarifies or simplifies a procedure.
DANGER
DANGER indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury.
WARNING
WARNING indicates a potentially hazardous situation, which, if not avoided, can result in death, serious injury or
equipment damage.
CAUTION
CAUTION indicates a potentially hazardous situation, which, if not avoided, can result in injury or equipment
damage.
CAUTION
CAUTION, used without the safety alert symbol, indicates a potentially hazardous situation which, if not avoided,
can result in equipment damage.
PLEASE NOTE
The word "drive" as used in this manual refers to the controller portion of the adjustable speed drive as defined by NEC.
Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by
Schneider Electric for any consequences arising out of the use of this product.

Before you begin
Read and understand these instructions before performing any procedure with this drive.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Read and understand this manual before installing or operating the Altivar 312 drive. Installation, adjustment, repair, and
maintenance must be performed by qualified personnel.
• The user is responsible for compliance with all international and national electrical code requirements with respect to grounding of
all equipment.
• Many parts of this 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.
• Before servicing the drive:
- Disconnect all power, including external control power that may be present.
- Place a “DO NOT TURN ON” label on all power disconnects.
- Lock all power disconnects in the open position.
- WAIT 15 MINUTES to allow the DC bus capacitors to discharge.
- Measure the voltage of the DC bus between the PA/+ and PC/– terminals to ensure that the voltage is less than 42 Vdc.
- If the DC bus capacitors do not discharge completely, contact your local Schneider Electric representative. Do not repair or
operate the drive.
• Install and close all covers before applying power or starting and stopping the drive.
Failure to follow these instructions will result in death or serious injury.
DANGER
UNINTENDED EQUIPMENT OPERATION
• Read and understand this manual before installing or operating the Altivar 312 drive.
• Any changes made to the parameter settings must be performed by qualified personnel.
Failure to follow these instructions will result in death or serious injury.
WARNING
DAMAGED DRIVE EQUIPMENT
Do not operate or install any drive or drive accessory that appears damaged.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
WARNING
LOSS OF CONTROL
• The designer of any control scheme must
- consider the potential failure modes of control paths and, for certain critical control functions,
- provide a means to achieve a safe state during and after a path failure.
Examples of critical control functions are emergency stop and overtravel stop.
• Separate or redundant control paths must be provided for critical control functions.
• System control paths may include communication links. Consideration must be given to the implications of unanticipated
transmission delays or failures of the link.
a
Failure to follow these instructions can result in death, serious injury, or equipment damage.

Documentation structure
The following Altivar 312 technical documents are available on the Schneider Electric website (www.schneider-electric.com) as well as on
DVD-ROM (reference VW3A8200).
Installation manual
This manual describes how to install and wire the drive.
Programming manual
This manual describes the functions, parameters and use of the drive terminal (integrated display terminal, optional graphic display terminal
and optional remote terminal).
The communication functions are not described in this manual, but in the manual for the bus or network used.
Simplified manual
This manual is an extract from programming and installation manual. This manual is delivered with the drive.
Quick Start sheet
The Quick Start describes how to wire and configure the drive to start motor quickly and simply for simple applications. This document is
delivered with the drive.
Communication manuals: CANopen, DeviceNet, Modbus and PROFIBUS DP
These manuals describe the assembly, connection to the bus or network, signaling, diagnostics, and configuration of the communicationspecific parameters.
They also describe the protocol communication services.
Communication variables guide
This manual defines the drive control processes and the drive variables which can be accessed by the communication buses.

Introduction
Presentation
This guide contains information on installation and describes the PROFIBUS DP services available. The "communication variables" guide
describes the operating modes, as well as the Altivar 312 variables and parameters which can be accessed via the communication bus.
The PROFIBUS DP communication card (catalog number VW3 A312 07) is used to connect an Altivar 312 drive to a PROFIBUS DP bus.
Data is exchanged in order to make use of all the Altivar 312 functions:
• Configuring functions
• Uploading adjustment parameters
• Control-signaling
• Monitoring
• Diagnostics
The PROFIBUS DP card has an open style connector.
The cable for connection to the PROFIBUS DP bus must be ordered separately.
Drive terminal displays
The graphic display terminal menus, available with the remote graphic display terminal option, are shown in square brackets.
Example: [MOTOR CONTROL] (drC-).
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).
Formats
In this manual, hexadecimal values are written as follows: 16#.

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.
Installing the card in the drive
DANGER
UNINTENDED EQUIPMENT OPERATION
• Do not plug or unplug the terminal board while drive is powered.
• Check the tightening of the fixing screw after any manipulation on the terminal board.
Failure to follow these instructions will result in death or serious injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Do not touch the terminal board before:
• removing power on the drive,
• removing any voltage on input and output terminals.
Failure to follow these instructions will result in death or serious injury.

Hardware setup
Install the card in ATV312 as follows:
1. Open the ATV312 front cover.
2 & 3. Remove the terminal board fixing screw and take off the ATV312 standard terminal board.
(Be careful not to lose the terminal board fixing screw when removed since it may be used again.)
This step does not apply if you are using an ATV312.... B (product without standard IO terminal).
4. Install the PROFIBUS DP card and secure it with the board fixing screw
(M3 tapping screw tightening torque: 0.7 to 0.8Nm).
5. Stick the new cabling label above the PROFIBUS DP option card.
Stick the PROFIBUS DP card nameplate near the ATV312 nameplate. (Be careful not to cover slits on the ATV312 enclosure)
6. Perform wiring on the PROFIBUS DP card (see page 11
7. Wire and screw the EMC clamps for the PROFIBUS DP cables (and control wires if required).
Note: To install or remove the terminal board, make it slide in or out in parallel with board.
