Introduction Programming Guide

1.4.2 Technical Overview

PROFIBUS

PROFIBUS is an international standard for eldbus

communication in automation technology (IEC 61158 and

IEC 61784). The member companies of the PROFIBUS

International User Community support the standard.

For information about PROFIBUS and downloads for

PROFIBUS DP and the PROFIdrive prole, refer to

www.Probus.com.

PROFIBUS DP-V1

The PROFIBUS DP protocol enables communication

between PROFIBUS masters and slaves.

Congure communication via MCT 10 Set-up Software.

Cyclic/acyclic communication

•PLC communicates with telegrams of constant

length.

•Fits time-critical requirements.

•Cyclic transmission via PPO types.

•Extended diagnosis.

130BA078.11

PLC

Illustration 1.1 PROFIBUS DP-V0

Features of a master class 1 connection:

•Cyclic data exchange (DP-V0).

•Acyclic read/write on parameters.

•Extended diagnosis.

The acyclic connection is xed and cannot be changed

during operation.

Features of a master class 2 connection:

•Initiate/abort acyclic connection.

•Acyclic read/write on parameters.

The acyclic connection can be established (initiated) or

removed (aborted) dynamically even when a master class 1

is active on the network. Use the DP-V1 acyclic connection

for general parameter access as an alternative to the PCV

parameter channel.

PLC

Master class 1

PC tool

Master class 2

Illustration 1.2 PROFIBUS DP-V1

The PROFIBUS DP extension DP-V1 allows acyclic as well as

cyclic data communication. This feature can be used by a

DP master class 1, for example PLC, as well as a DP master

class 2, for example PC tool.

2 Safety

2.1 Safety Symbols

The following symbols are used in this manual:

WARNING

Indicates a potentially hazardous situation that could

result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation that could

result in minor or moderate injury. It can also be used to

alert against unsafe practices.

NOTICE

Indicates important information, including situations that

can result in damage to equipment or property.

2.2 Qualied Personnel

Correct and reliable transport, storage, installation,

operation, and maintenance are required for the trouble-

free and safe operation of the frequency converter. Only

qualied personnel are allowed to install and operate this

equipment.

Qualied personnel are dened as trained sta, who are

authorized to install, commission, and maintain equipment,

systems, and circuits in accordance with pertinent laws and

regulations. Also, the qualied personnel must be familiar

with the instructions and safety measures described in

these operating instructions.

2.3 Safety Precautions

WARNING

HIGH VOLTAGE

Frequency converters contain high voltage when

connected to AC mains input, DC supply, or load sharing.

Failure to perform installation, start-up, and maintenance

by qualied personnel can result in death or serious

injury.

•Only qualied personnel must perform instal-

lation, start-up, and maintenance.

WARNING

UNINTENDED START

When the frequency converter is connected to AC mains,

DC supply, or load sharing, the motor may start at any

time. Unintended start during programming, service, or

repair work can result in death, serious injury, or

property damage. The motor can start with an external

switch, a eldbus command, an input reference signal

from the LCP or LOP, via remote operation using MCT 10

Set-up Software, or after a cleared fault condition.

To prevent unintended motor start:

•Press [O/Reset] on the LCP before

programming parameters.

•Disconnect the frequency converter from the

mains.

•Completely wire and assemble the frequency

converter, motor, and any driven equipment

before connecting the frequency converter to

AC mains, DC supply, or load sharing.

WARNING

DISCHARGE TIME

The frequency converter contains DC-link capacitors,

which can remain charged even when the frequency

converter is not powered. High voltage can be present

even when the warning LED indicator lights are o.

Failure to wait the specied time after power has been

removed before performing service or repair work can

result in death or serious injury.

•Stop the motor.

•Disconnect AC mains and remote DC-link power

supplies, including battery back-ups, UPS, and

DC-link connections to other frequency

converters.

•Disconnect or lock PM motor.

•Wait for the capacitors to discharge fully. The

minimum duration of waiting time is specied

in the chapter Safety in the operating

instructions supplied with the frequency

converter.

•Before performing any service or repair work,

use an appropriate voltage measuring device to

make sure that the capacitors are fully

discharged.

Safety VLT®PROFIBUS DP MCA 101

WARNING

LEAKAGE CURRENT HAZARD

Leakage currents exceed 3.5 mA. Failure to ground the

frequency converter properly can result in death or

serious injury.

•Ensure the correct grounding of the equipment

by a certied electrical installer.

WARNING

EQUIPMENT HAZARD

Contact with rotating shafts and electrical equipment

can result in death or serious injury.

•Ensure that only trained and qualied personnel

perform installation, start-up, and maintenance.

•Ensure that electrical work conforms to national

and local electrical codes.

•Follow the procedures in this guide.

CAUTION

INTERNAL FAILURE HAZARD

An internal failure in the frequency converter can result

in serious injury when the frequency converter is not

properly closed.

•Ensure that all safety covers are in place and

securely fastened before applying power.

bus network have a unique station address.

Select the PROFIBUS address of the frequency converter

via:

•Hardware switches.

•Parameter 9-18 Node Address.

•The PROFIBUS command SSA (set station

address).

3.1.1 Setting the PROFIBUS Address using

the DIP Switches

To set the PROFIBUS address using the DIP switches:

1. Switch o the supply.

2. Select an address in the range 0–125. Factory

setting is 127.

3. For location of the DIP switches, refer to

Illustration 3.1 and Illustration 3.2.
