ABB ACS850 machinery drives

Introduction to ACS850

ABB machinery drives are designed to meet the production

and performance needs of machine builders, system

integrators, panel builders and end users in a broad range

of applications. ACS850 drives are ideal for applications like

cranes, extruders, conveyors, winders, pumps, fans and

mixers in industries such as material handling, plastic and

rubber, food and beverage, textile and metals.

The drives can be configured to meet the precise needs

of industries and order-based configuration is an integral

part of the offering. Covering a wide power and voltage

range with standard and optional features, the drives are

readily programmable, making their adaptation to different

applications easy.

Wide range of options

ACS850 drives offer a wide range of built-in options such

as different I/O and communications. A wide selection of

external accessories is also available. The flexibility and

programmability of the drives make them suitable for many

applications in different industries.

Based on direct torque control technology, the ACS850

offers highly advanced features. The ACS850 standard

control program provides solutions to virtually all AC drives

applications such as mixers, separators, extruders and

conveyors.

Fast and easy commissioning

The ACS850 standard control program offers flexibility and

extensive parameter settings. It consists of a simple, readymade program that can easily be modified to meet specific

application needs. Commissioning is also simplified by several

standard software features.

Pre-programmed protection functions

A wide range of features provide protection for the drive,

motor and the process:

− Ambient temperature

− DC overvoltage

− DC undervoltage

− Drive temperature

− Input phase loss

− Overcurrent

− Power limits

− Short circuit

Programmable protection functions:

− Adjustable power limits

− Control signal supervision

− Critical frequencies lock-out

− Current and torque limits

− Earth fault protection

− External fault

− Motor phase loss

− Motor stall protection

− Motor thermal protection

− Motor underload protection

− Panel loss

Program customization

In addition to standard control program functionalities the

ACS850 offers function block programming which makes it

possible to replace relays or even a PLC.

Removable memory unit

A removable memory unit provides easy maintenance by

storing the complete firmware including all user settings

and motor data. Thus, if the power unit or control unit is

replaced, the drive can be re-commissioned without any

reprogramming, just by moving the memory unit.

The removable memory unit:

− Stores the drive software and parameter settings

− Allows fast and easy recommissioning

− Enables software and parameter configuration at workshop

instead of doing it on-site

The features of ACS850 drives are designed to enhance their

reliability and durability as well as the easiness of use. Also

several advanced functions make the drives easy to use.

These functions can be accessed either via the user-friendly

assistant control panel or DriveStudio PC tool.

Macros

Several macros which have pre-set, application-specific

parameter settings are available as standard in each drive.

These pre-programmed parameter settings enable fast and

easy commissioning by adjusting all the relevant parameters

in just a couple of clicks.

Startup assistant

The intelligent and intuitive startup assistant allows first time

users to quickly get up to speed and customize the drive

according to their needs. This is complemented by a built-in

help function to make parameter-by-parameter setting easy.

This way the drive can be quickly commissioned, even without

manuals.

Maintenance assistant

The maintenance assistant reminds the user about the

drive’s preventive maintenance schedule or routine, or that

of its associated components such as motor, cabinet air

inlet filters and input contactors. It reminds users of planned

maintenance needs based on running hours, operating hours

or relay switching to reduce unplanned process interruptions.

Diagnostic assistant

Each ACS850 drive is equipped with a diagnostic assistant

that helps in locating the cause of any disturbance to the drive

and even suggests possible remedies. This reduces process

downtime by making repair or adjustments quicker and easier.

Energy saving features

− A calculator showing the used and saved energy, displayed

in kWh, currency (€ or $) or volume of CO2 emission. Data

is calculated by reference values stored in the drive by the

user.

− An energy efficiency optimizer that adjusts the motor flux in

such a way that the total efficiency is maximized.

− A load analyzer showing the load profile of the drive.

Short/long menus

The user interface can be configured so that it displays only

Standard I/O connections

ACS850 drives have one of the most extensive offerings of

standard I/Os on the market. Analog and digital I/O channels

are used for different functions such as control, monitoring

and measurement purposes (eg, motor temperature).

− Control voltage supply: external supply (24 V DC) input for

the control unit

− Digital I/O: 6 x DI, 2 x DI/O (can be used also for pulse train

inputs or outputs, max 32 kHz), 3 x RO

− Analog I/O: 2 x AI (mA or V), 2 x AO (mA)

− Thermistor input: motor thermistor (PTC)

− Start interlock: drive interlock input

− Embedded Modbus link as standard, galvanically isolated

for trouble-free operation and can be alternatively

configured as a high speed drive-to-drive link for masterfollower operation

− Safe torque off (STO): designed for Safety Integrity Level 3

(SIL 3) according to IEC 61508

− Control panel connection: PC tools and control panel

connection (RJ45)

− Memory unit connection: complete drive configuration and

settings are stored in the removable memory unit
