Overview of DriveSize


This chapter tells you how to install and start the DriveSize program. It also provides

general information about using DriveSize.

DriveSize installation instructions

Note:Version-specific installation instructions for DriveSize are given in the readme file.

The file contains also hardware and system requirements. Read the readme file carefullybefore installing the software.

Program structure

DriveSize consists of a user interface with dimensioning functions and of productdatabases. The databases contain catalog motors and drives and the units/modules of

the drives. Dimensioning of customer-specific motors is based on ABB Sophi, which hasbeen developed by ABB Oy / Machines. The DriveSize installation package includes ABB

Sophi.

The program follows the common user interface guidelines of Microsoft Windows.

When you select first one of the AC drive product series, the associated productdatabase opens. The dimensioning cases are called projects. You can save the selectionresults for the project into their own project file (XML file). You can then generatetechnical reports in the MS Excel format and you can attach the reports to the project and

drive documentation.

Dimensioning


This chapter describes how to make dimensioning or retrieve a previously saved project

file.

Starting a new project

You can make a complete drive system design with DriveSize in many ways. The

following list is an overview of the tasks you can perform with DriveSize. Later on you willlearn shortcuts to perform the same tasks more quickly.

Double click a product family or select one and click Openin the New projectselection (See Figure 1: New project8.6cm).

You may enter project information. Select Project Infoon the Filemenu. (See Figure2: Project information).

If ambient conditions deviate from normal selectAmbient Condit ionson the Datamenu and set new ones. (See Figure 3: Ambient conditions).

If the network data, voltages and frequency deviate from your previous settingschange them from main window (See Figure 4: The main dimensioning window). InSystem configuration, highlight a network/transformer. (See Figure 5: Network data

and Transformer load definition).

In System configuration, highlight the motor and enter load definitions (See Figure

6: Motor load and specifications data). Let DriveSize to select the motor. If you wish tochange the motor, use the User selection functions.

Let DriveSize to select the drive or inverter once the motor/motors are known.MultiDrive systems normally contain many inverters and motors and DriveSize is able

with one shot select all. You can also select manually the drive or inverter.

14 Dimensioning

For a multidrives, the dimensioning of line supply unit is done when the inverters andmotors have been defined.

Note:The supply unit type has also effect on the motors.

In System configuration, use a toolbar icon or a menu command or press Ctrl+Dto

control the dimensioning for a selected unit. You can make dimensioning one by one(Ctrl+D) or dimension all units at same time (Ctrl+A).

Selecting a product series

When you start DriveSize without a project file, the Welcomewindow opens. If you are

starting a new project, you must select a product series first. Figure 1: New project8.6cmshows the Welcomewindow.

Figure 1: New project8.6 cm

Use Project Info on the Filemenu andAmb ient Condit ionson the Datamenu if you

wish to change the defaults. You can change this information later with menu commands.

Network and transformer data

The primary voltage does not have effect on motor and drive choices but if you select a

value that is too high it prevents you from selecting a transformer. The default systemfrequency is 50 Hz but it changes to 60 Hz if valid. The default system frequency has a

direct effect on possible secondary voltage levels as well as on the motor databases. Thelogic of DriveSize assumes that in the 60 Hz countries the standard motors are 60 Hzmotors. This limitation is not valid with the AC Drives.

Short-circuit power is essential when network harmonics are calculated. DriveSize has apractical upper limit for short-circuit power.

Figure 5: Network data and Transformer load definitionshows the Network dataandTransformer loaddialog.

DriveSize calculates the transformer load power from the motor base powers and

efficiencies and power factors. You can allow DriveSize to use these values, but inspecial cases you can use your own values.

The software includes Oil immersedand Vacuum Cast Coil Drytypes of transformers.

Entering motor speeds and loads

The Motor speedand Motor loadinput fields vary with different load types.

DriveSize does not accept gear information. If a gear is involved, convert the values tomotor speed manually or use an Excel sheet.

DriveSize does not consider dynamic torque when it accelerates inertias up and down.When remarkable dynamic torque exists, include it as short term overloads.

Base speed

Base speed is the minimum mechanical speed of a motor where the base power isrequired.

Note: Use exact values for base speed. Use 1456 (not1500) because the rated speedsof motors are also exact.

Base power

Base power is the mechanical power of a motor. This is used as the base value for alloverloads. Note that motor thermal dimensioning is based on worst 10 min RMS by

default. For motor selection there is an option to skip RMS computing. Select Skip RMS-

computing of overloadsfrom Toolsmenus Options. You can use a round number like10 kW, 50 kW or 100 kW and type in overloads based on the base value you select. Basepower is normally positive but negative values are acceptable.

Fill in the required load that is on the shaft notthe rated power of the motor. Specify thereal required shaft power of the loading machine. In VSD applications, the motors arealways slightly derated.

Base overload

Base overload defines the maximum required power together with base power for theoverload time. The power is overload in percent x base power. Overload in percent is

normally positive but a negative value means that the overload has a different sign thanthe base power.

Min speed

If the minimum speed is too low, DriveSize selects for the motors and drives a size that islarger than necessary. In DriveSize, the minimum speed is not exactly the minimumspeed of the motor but a speed that is used without interruptions of, for example,

30 minutes. DriveSize assumes that the duty cycle continues without stopping and

DriveSize selects the motor and drive accordingly. If the minimum speed is critical, youcan see it from the results/graphs. The default minimum speed is 300 rpm or 400 rpm.

Max speed

A maximum speed that is too high can have a negative impact on the motor size. If themaximum speed is much higher than the base speed and the overload in percent is high,

the absolute maximum torque of the motor can be a limiting factor.


22/59

22 Dimensioning

Overload at max speed

Due to the reasons stated above, the overload in percent at maximum speed can be

given a different normally lower - value than the overload in percent at base speed. Thisis valid for constant power load types.

Figure 6: Motor load and specifications data


23/59

23

One-time overload at start

Figure 7: Motor input datashows where you select the values forOne-time overload at

start.OL[%]

The starting torque is OL% x base torque. The base torque is calculated from the basepower and base speed. The valid range for OL% is from 1% to 1000%.

OL timeis the duration of the starting overload in seconds.

OL max speedtells DriveSize at which speed the overload ceases. Use low values. Ifthe OL maximum speed is equal to the base speed and OL% is high, the power limit of

the inverter can force DriveSize to select a larger drive.

torque cases where the minimum speed is very low.

For large motors there are other selections available.

Max speed rule Standard= Standard maximum speeds is used.

Metal fan= The higher speed limit of the metallic fan is used.

Separate fan= Higher maximum speed is available when force ventilated.

temperature class given in motor catalogues.

Tmax margin 43%, 30% or 20%.Motor catalogues give rough maximum torque values andsome margin has to be provided. The margin from actual overload torque to


25/59

25

Tmax must be 43%, 30% or 20%.

Motor selection in general and User selection

DriveSize usually selects the most suitable motor from the technical point of viewconsidering specification. However, sometimes you may want to select another motor. In

these cases, you can choose an optional motor from the User selection list. Figure 20:User selection view for motorshows the alternative selections.

Addit ional derating requirements

Terminal box mounting and possible special winding insulation have an effect on thetemperature rise of the motor. DriveSize does not take these extra deratings into account.It is assumed that standard insulation and a top-mounted terminal box are used. If not,some extra margin must be reserved. The necessity of derating can also be a sum of

these both items.

Reinforced insulation

Reinforced insulation is recommended when motor voltage is higher than 500 V. Aboutthree per cents (3%) additional derating of the continuous loadability curve is required

when reinforced windings are used. Reserve at least 3% margin in DriveSize for this

purpose.

Terminal boxes

Terminal boxes are mounted either on the top of the motor or on the left or right side.Availability of the terminal box mounting options depends on the type of the motor and

the motor frame size. Three per cents (3%) additional derating is needed for thecontinuous loadability curve when the terminal box is mounted on the side of the motor oron the ND end of the motor. As standard, terminal boxes are mounted on the top of the

motor and extra margin is unnecessary. Reserve at least 3% margin in DriveSize for this

purpose.

Note: Check the availability of force ventilation and accessories from the motor

manufacturer.

Inverter input data

This section describes how to enter the drive/inverter data. Figure 8: Inverter input data

shows the inverter input data.

Entering inverter loadThe load of the inverter consists of the motor currents and frequencies. DriveSize

calculates the load currents based on the selected motor characteristics (power factor,

efficiency, pole pairs), shaft loads, shaft speeds and motor voltage.

You can change the inverter load value by entering new currents. In this case, DriveSize

uses the currents you have given manually instead of the calculated currents. The rest ofthe data that DriveSize uses in calculation is based on the motor. If you have not selectedthe motor characteristics, DriveSize uses the default values of the software.

available: the braking voltage and motor voltage. These parameters are mutually

exclusive.

Selecting liquid cooled supply unit

When you select the liquid cooled (LC) supply option in the Coolingspecification, two

new specifications Glycol concentration and Liquid temperature appear. Thesespecifications determine also all the inverters connected to that supply unit. The coolingmethod of line supply unit is valid also for all the inverters connected to that line supplyunit.

This option determines also the cooling method for all the inverters

connected to that line-up.

Pulse 6-pulse, 12-pulse, 18-pulse, 24-pulse (DSU, TSU). When the 12-pulse

option is selected, the transformer must be of a three-winding type.

Braking Voltage (%) 85, 90, 100 (TSU)

A lower braking voltage means that prior to braking, the DC voltage is

reduced.

Note:A lower DC voltage means that there is less available motor voltageand therefore the maximum torque a motor produces is also lower. This

setting has to be understood so that TSU makes a lower than nominal DC

voltage and the motor voltages are also lower. In this case, TSU can quickly

change from motoring to regenerating.

Motor Voltage (V) 380, 400, 415, 500, 525, 660, 690, 830 for 50 Hz and 380, 440, 460, 480,

Customer-specific motors

Some motors are called customer-specific because they are not picked from any list but

the rated power and frequency are computed from load requirements. When youdimension a customer-specific motor like HXR, AMA or AMI, ABB Sophi automaticallyselects the number of poles and the field weakening point (Fwp frequency). After theautomatic selection you can alter the value of field weakening frequency between the

given limits. The minimum and maximum limits for field weakening are shown in theselected motor data. Additionally, there is also a value for the recommended maximum(Rec). Before you change the value ofFwp frequency,select the pole number. When

Existing motors

You can define an existing motor in the Existing Motordialog. It automatically opens

when you select the Existing motor type. Figure 15: Existing Motor dialog boxshows

the dialog for an existing motor. The loadability curves of the ABB standard motors areused for existing motors. DriveSize assumes that the existing motor is already installed

and driving the load. The loadability of an existing motor is not checked, but the graphsshow if it is undersized according to the rules for standard motors.

Figure 15: Existing Motor dialog box

User motorsYou can make dimensioning for motors from your own motor list. This section describes

how you can import your own motor database into DriveSize.

The format of the motor list is an Excel worksheet with specified column headers and one

row for the information of one motor. The motor list is expected to start on the firstworksheet in the book and the upper right corner is cell A1. Before you can use the motorlist, import it to a UserMotor database in DriveSize. The import is always a full import and

all previously existing user motors are removed when you import a new list.

User motors are used independently from supply frequency but the motor voltage mustmatch the supply voltage. The rating value conversion from one voltage to another is not

done for user motors (You can make the conversion yourself in Excel.) Different voltagesmust have separate rows in the database.

Creating a user motors fi le

Enter the motor data and loadability curves in UserMotors.xls. By default, you can findthis file in your working directory in

C:\\ProgramFiles\DriveWare\DriveSize\VsdSize20\system. You can change the file name

but not the extension.

Importing from a file

To import new data to the database, select File -> User motors -> Import from fi le. This

action overwrites the existing UserMotor database.

Figure 16: Import Database window

The import function validates the information in the Excel sheet before updating thedatabase. The validation rules are: Correct column headers

Correct data types (text, numeric)

All numeric values must be > 0

Text values must fit into a maximum length

The frequency column must be between 8400 (Hz) so that also values other than50 Hz or 60 Hz are accepted.

The voltage must be known by DriveSize

In case of import errors, the program tells you which values are not accepted and the

import is cancelled.

The import date is stored in the Generaltable and it is visible in theAbout box.

If there is at least one motor imported to the database, a new item is added to the Motortype list: User definedin the motor specification grid.

When you select User defined, DriveSize updates the Familylist with all families fromthe Database. The other specification items are: Family: Not specified, + rest of list from the database

Pole number: Automatic, 2, 4, 6, 8, 10, 12

This chapter describes how to interpret DriveSizes Resultsshown on screen.

Dimensioning results

DriveSize always try to select some unit. The selection may not be optimal but it providesa result quickly. When you change the input data, you get another result. DriveSize

computes the selections quickly but you make the f inal decision. Figure 17: Main

dimensioning window shows an example of the motor results.

Figure 17: Main dimensioning windowYou can read the dimensioning results in the main dimensioning window, but you can findmore detailed information in the dimensioning Resultview where results appearnumerically or in the Graphview where results appear graphically. If you are not satisfied

with the software dimensioning result, make your own selection. This is possible in theUser Selectionview. All the individual sections dimensioned for the project can be seen

in the List o f Selectedview.

Result view

The Resultview shows the results in a numeric form for the item you have highlighted.

The view is similar for motors, inverters and incoming units. The Specifications datashows the user requirements. The Catalogue datadisplays the unit and selectioncalculations in different points and shows how the unit meets the requirements. TheSelection datahas columns forRequired, Resultand Margin values. The required data

is calculated from the user load demands. The result data is based on selected unit(motor, drive etc). The margin indicates the percentage of capacity still available(difference between the input requirements and the resulting data of the component).

You can see in the selection data the required load margin for the selected unit. Whenthe margins are positive, the unit meets the requirements.

Note:A large margin causes over-dimensioning. If the margin is negative, the unit cannot

meet the requirements. When the motor type is ACS800, where a thermal model is used,the margin of continuous current can be negative when the ambient temperature is below

40 C.

52 Network Check

Network Check


This chapter describes how to compute the effects of drives on a network. Harmonics

calculation is based on discrete Fourier transformation and tabulation.

Network Check view

With Network Checkyou can calculate: the network harmonics and power factor for an individual drive

the network harmonics and power factor for a line supply unit

combined harmonics for several units.

Both the voltage and the current harmonics are calculated. DC voltage calculations

provide DC link voltage. Figure 22: Network Check viewshows an example.

Tip:Compute the combined harmonics, not harmonics for individual drives because theparallel drives will smoothen and, in some cases, compensate each other. Combine ISUand DSU drives.
