Introduction to the manual

What this chapter contains

This chapter gives basic information on the manual.

Applicability

The manual is applicable to the cabinet-installed ACS880-207 IGBT supply units that form

a part of an ACS880 multidrive system.

Safety instructions

Follow all safety instructions delivered with the drive.

• Read the complete safety instructions before you install, commission, use or

service the drive. The complete safety instructions are given in ACS880 multidrive and

multidrive modules safety instructions (3AUA0000102301 [English]

• Read the software-function-specific warnings and notes before changing the

default settings of the function. For each function, the warnings and notes are given in

the section describing the related user-adjustable parameters.

• Read the task-specific safety instructions before starting the task. See the section

describing the task.

Target audience

This manual is intended for people who install, start-up and service multidrives. Read the

manual before working on the drive. You are expected to know the fundamentals of

electricity, wiring, electrical components and electrical schematic symbols.

10 Introduction to the manual

Purpose of the manual

This manual helps in installing, commissioning, using and maintaining a multidrive with

and IGBT supply unit.

Contents of the manual

• Introduction to the manual

• Operation principle and hardware description

• Electrical installation

• Installation checklist

• Start-up

• Maintenance

• Technical data

• The control unit.

Related documents

The multidrive user documentation consists of technical drawings and a set of manuals.

The technical drawings are tailor-made for each drive. The composition of the manual set

depends on the composition of the drive, eg, which supply unit type, options and inverter

control program has been ordered by the customer. The main manuals have been listed

on the back of the front cover.

Categorization by frame size, option code and item

designation

The instructions and technical data which concern only certain unit or frame sizes are

marked with the size identifier.

The unit size can be identified from the basic code visible on the type designation label, for

example, ACS880-207-0420A-3 where 0420A is the unit size. The option codes of the unit

are listed after the plus sign. Section Type designation keys on page 35 explains the type

designation code in detail.

The frame size of the IGBT supply module is, for example, R8i. The Ratings table on

page 109 lists the frame sizes.

Some device names in the manual include the item designations in brackets, for example

[Q2] to make it possible to identify the components in the circuit diagrams of the drive.

Term/Abbreviation Description

Operation principle and hardware description 13

Operation principle and

hardware description

What this chapter contains

This chapter describes the operation basics and the hardware of the IGBT supply unit

(ACS880-207).

Operation principle

IGBT supply unit rectifies three-phase AC current to direct current for the intermediate DC

link of the drive. The intermediate DC link supplies the inverters that run the motor. There

can be one inverter unit only (single drives) or several inverter units (multidrives)

connected to the intermediate circuit.

The

LCL filter is an essential part of the IGBT supply unit. It suppresses the AC voltage

distortion and current harmonics. The high AC inductance smooths the line voltage

waveform distorted by the high-frequency switching of the converter. Capacitive

component of the filter effectively filters the high-frequency (over 1 kHz) harmonics.

14 Operation principle and hardware description

 Main circuit diagram

The following figure shows the simplified main circuit diagram of the rectifier.

 Charging

Charging is always needed to power up the DC link capacitors smoothly. Discharged

capacitors cannot be connected to the full supply voltage. The voltage must be increased

gradually until the capacitors are charged and ready for normal use. In ACS880-207 IGBT

supply units, a resistive charging circuit consisting of fuses, a contactor and charging

resistors, is used. The resistive charging circuit is in use after power-up as long as DC

voltage has risen to a predefined level.

The IGBT supply control program has a function for controlling the charging circuit in the

IGBT supply unit. For further information, see the firmware manual.
