Safety Instructions

Overview

Installation and Maintenance Safety

The complete safety instructions for the ACA 6xx in Safety and Product Information (EN code: 63982229) and for the ACS800-17 in Hardware Manual (EN code: 64638505) must be followed when installing,

operating and servicing the drives. Study the complete safety instructions carefully.

These safety instructions are intended for all who work on the ACA 6xx or the ACS 800-17. Ignoring these instructions can cause physical injury or death.

WARNING! All electrical installation and maintenance work on the drive should be carried out by qualified electricians.

Any installation work must be done with power off, and power is not to be reconnected unless the installation work is complete. Dangerous residual voltages remain in the capacitors when the disconnecting device is opened. Wait for 5 minutes after switching off the supply before starting work. Always ensure by measuring that the voltage between the terminals UDC+ and UDC- and the frame is close to 0 V and that the supply has been switched off before performing any work on the equipment or making main circuit connections.

If the main circuit of the inverter unit is live, the motor terminals are also live even if the motor is not running!

Open switch fuses of all parallel connected inverters before doing installation or maintenance work on any of them. These switch fuses are not included in the the ACS 800-17.

When joining shipping splits, check the cable connections at the shipping split joints before switching on the supply voltage.

If the auxiliary voltage circuit of the drive is powered from an external power supply, opening the disconnecting device does not remove all voltages. Control voltages of 115/230 VAC may be present in the digital inputs or outputs even though the inverter unit is not powered. Before starting work, check which circuits remain live after opening of the disconnecting device by referring to the circuit diagrams for your particular delivery. Ensure by measuring that the part of the cabinet you are working on is not live.

Safety Instructions

The control boards of the converter unit may be at the main circuit potential. Dangerous voltages may be present between the control boards and the frame of the converter unit, when the main circuit voltage is on. It is critical that the measuring instruments, such as an oscilloscope, are used with caution and safety as a high priority. The fault tracing instructions give special mention of cases in which measurements may be performed on the control boards, also indicating the measuring method to be used.

Live parts on the inside of doors are protected against direct contact. Special safety attention shall be paid when handling shrouds made of sheet metal.

Do not make any voltage withstand tests on any part of the unit while the unit is connected. Disconnect motor cables before making any measurements on motors or motor cables.

WARNING! Close switch fuses of all parallel connected inverters before starting the drive.

Automatic Resets

Do not open the drive section switch fuses when the inverter is running.

Do not use Prevention of Unexpected Start for stopping the drive when the inverter is running. Give a Stop command instead.

CAUTION! Fans may continue to rotate for a while after the

disconnection of the electrical supply.

CAUTION! Some parts like heatsinks of power semiconductors and toroidal cores on motor cables inside the cabinet remain hot for a while after the disconnection of the electrical supply.

WARNING! If an external source for start command is selected and it is ON, the drive will start immediately after fault reset.

Dedicated Transformer

Safety Instructions

WARNING! Frame size R11i and above must be supplied with a transformer dedicated to drives and motors or equipment of equal or higher power, or with a transformer equipped with two secondary windings, one of which is dedicated to drives and motors. Resonances might occur if there is capacitive load (e.g. lighting, PC, PLC, small power factor compensation capacitors) in the same network with the drive. The resonance current might damage some unit in the network.

Page A-13, Second Environment CHANGED:

The ACA 635 supply sections comply with the EMC Directive in industrial low-voltage network, and IT networks (unearthed mains) with the following provisions. For ACS800-17 units, refer to ACS800-17 Hardware Manual (EN code 64638505).

1. The motor and control cables are selected as specified in the

Hardware Manual.

2. The drive is installed according to the instructions given in the

Hardware Manual.

3. Maximum cable length is 100 metres.

WARNING! The drive may cause radio interference if used in a residential or domestic environment. The user is required to take measures to prevent interference, in addition to the requirements for CE compliance listed above, if necessary.

Note: It is not allowed to use EMC filters on an unearthed mains supply network, unless the filters are able to withstand the unearthed network. (EMC filters are used to minimise the RFI emission of the unit.)

Note: With cables longer than 100 metres, the ACA 635 supply sections comply with the EMC Directive in restricted distribution mode when the installation is described in an EMC plan (a template is available from the local ABB representative).

Contents

This chapter describes the intended audience and contents of this manual. It contains a table referring to tasks described in other manuals.

This manual is intended for people who plan the installation, commission, use and service the drive equipped with an IGBT supply. Read the manual before working on the drive. You are expected to know the fundamentals of electricity, wiring, electrical components and electrical schematic symbols.

The parameters of the IGBT Supply Unit (ISU) Program listed in this manual need not be set in a normal start-up procedure or in normal use. However, the ISU parameters can be viewed and

changed using the Control Panel.

This manual applies to the ACA 635 supply sections and ACS 800-17 drives which contain the IGBT Supply Unit.

The control program of the IGBT Supply Unit is described in the following chapters: Chapter 6 – Firmware Description, Chapter 7 –

Fault Tracing and Chapter 8 – Parameters.

Safety Instructions contain installation and maintenance safety

instructions.

Chapter 2 – Operation Basics describes the operation of the IGBT

Supply Unit.

Operation of ISU

Main Circuit Diagram

Supply network

The ISU is a four-quadrant switching-mode converter, i.e., the power flow through the converter is reversible. The AC current of the ISU is sinusoidal at a unity power factor. As a default, the ISU controls the DC link voltage to the peak value of the line-to-line voltage. The DC voltage reference can be set also higher by a parameter.

A diagram of the main circuit of the IGBT supply is shown below.

Control and Gate Drivers

Common DC bus

LCL Filter

Control

Converter

The control and modulation is based on the Direct Torque Control (DTC) method typically used in ACS 600 motor control. Two line currents and DC link voltage are measured and used for the control. The control boards are similar to the boards of the inverter.

Voltage and Current Waveforms

The high frequency switching and high du/dt slightly distorts the voltage waveform at the input of the converter. The depth of the voltage notches depends on the ratio of network inductance to total line inductance (network + LCL filter inductance).

Distortion

Spectrum of the Voltage

DIstortion

IGBT supply unit does not generate characteristic current/voltage overtones llike a traditional 6- or 12-pulse bridge does, because of the sinusoidal waveform of the line current. The Total Harmonic Distortion (THD) in voltage depends slightly on the Short Circuit Ratio in the Point of Common Coupling (PCC), refer to Appendix A – Technical Data.

A typical spectrum of the voltage distortion at the output of the transformer is shown below. Each harmonic is presented as a percentage of the fundamental voltage. n denotes the ordinal number of the harmonic.
