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.

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 message that follow this symbol to avoid possible injury or death.

PLEASE NOTE

DANGER

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.

Product Related Information

UNINTENDED EQUIPMENT OPERATION

• Read and understand this manual before installing or operating the Altivar 212 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.

DANGER

6 S1A53844 01/2011

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

• Read and understand this manual before installing or operating the 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.

WARNING

DAMAGE 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 (1).

Failure to follow these instructions can result in death, serious injury, or equipment damage.

(1) For additional information, refer to NEMA ICS 1.1 (latest edition), “Safety Guidelines for the Application, Installation, and

Maintenance of Solid State Control” and to NEMA ICS 7.1 (latest edition), “Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems.”

Introduction

Data exchanges give access to all Altivar 212 functions:

• Control (start, stop, reset, setpoint),

• Monitoring (status, current, voltage, thermal state...),

• Diagnostics (alarms),

• Settings,

• Configuration.

The communication port has an RJ45 and an open style connector for the connection to the network. At the physical layer, it supports 2-wire RS485 and transmission speed at 9600 or 19200 bps.

4 Modbus functions are available:

• 3 (16#03) Read Holding Registers

• 6 (16#06) Write Single Register

• 16 (16#10) Write Multiple Registers

• 43/14 (16#2B/0E) Read Device Identification

Function 3 has a restricted implementation:

• with length 1 it permits to read any parameter of the drive, one by one, see page 33.

• with lengths 1 to 5 it permits to read a particular block of 1 to 5 indirect parameters. These 5 parameters

can be configured through the operation panel to relevant monitoring parameters, see page 34.

Function 16 has a restricted implementation:

• with length 1 it permits to write any writable parameter of the drive, one by one, see page 37.

• with length 1 to 2 it permits to write a particular block of 1 to 2 indirect parameters. These 2 parameters can

be configured through the operation panel to relevant control parameters, see page 38.

Protection Against Interference

•

Use the Schneider Electric cable with 2 pairs of shielded twisted conductors (reference: TSXCSA100, TSXCSA200, TSXCSA500).

• Keep the Modbus cable separated from the power cables (30 cm (11.8 in.) minimum).

• Make any crossovers of the Modbus cable and the power cables at right-angles, if necessary.

For more information, please refer to the TSX DG KBL E manual: “Electromagnetic compatibility of industrial networks and fieldbuses”.

Configuration of the communication interruption 28

The settings of communication-related parameters can be changed from the operation panel or from Modbus (PLC, computer or controller) or from graphic display option.

Topic Page

Note that there are two types of parameters: parameters whose settings take effect immediately after the setting and parameters whose settings do not take effect until the drive is turned back on or reset. In the table below, these 2 types are mentioned in the column "valid" by "After setting" and "After power cycle".

Notes:

• Baud rate and parity bit should be uniform inside the same network.

• Modbus address should not be duplicate inside the same network.

• Stop bit isn't configurable. ATV212 Tx is 2 stop bit, Rx is 1 or 2 stop bits. This permits a good comunication

with Master in 1 and 2 stop bits.

• F800 and F801 parameters are used to define the baudrate and parity of RJ45 port.

• F820 and F821 parameters are used to define the baudrate and parity of Open style connector port.

• F802 and F803 parameters are used to define the modbus address and communication time out for

both ports (RJ45 et Open style connector). Set F802 between 1 to 247 (address 0 is not active).

• F807 parameter enables to select the communication command channel: RJ45 or Open style connector.

The port not set as the communication command channel may be used for monitoring purposes to check that the setting change on F807 was effectively taken into account.
