DANGER!

Always disconnect the supply voltage before touching any

electricalcomponentinsidethe inverter.

Many components are charged with high voltage and/or in

movement (fans), even after the incomingAC power supply has

beendisconnectedor switchedOFF. Waitatleast10 minutesfor

thetotal discharge of the power capacitors.

Alwaysconnecttheframeof the equipmentto theground(PE)at

thesuitable connectionpoint.

ATTENTION!

All electronic boards have components that are sensitive to

electrostatic discharges. Never touch any of the electrical

components or connectors without following proper grounding

procedures. If necessary to do so, touch the properly grounded

metallicframe or use a suitable ground strap.

vector control (VVC: voltage vector control) or V/F (scalar);

bothtypesof control can be setaccordingtotheapplication.

Inthevectorcontrolmode,themotorperformanceisoptimized

relatingto torque and speed regulation.

The"Self-Tuning"function,availableinvectorcontrol,permits

the automatic setting of the inverter parameter from the

identification(alsoautomatic)of the parametersof the motor

connectedatthe inverteroutput.

The V/F (scalar) mode is recommended for simpler

applicationssuchas pumpandfandrives.In thesecasesone

can reduce the motor and inverter losses by using the

"QuadraticV/F" option, thatresultsinenergysaving.

TheV/Fmodeisalsousedwhenmorethanonemotorshould

inverter is enabled. Maintain the electrical continuity of the

motorcable shield.

Dynamic braking (DB)

When inverterswith dynamic braking (DB) are used, the DB

resistorshall be mountedexternally. Figure 8.31 shows how

to connect the braking resistor. Size it according to the

application,notexceedingthemaximumcurrentof thebraking

circuit. For the connection betweeninverter and the braking

resistor, use twisted cable. Provide physical separation

betweenthis cable and the signal and control cables. When

the DB resistor is mounted inside the panel, consider watt

lossgeneratedwhendefining thepanelventilation.

DANGER!

Theinvertermustbe grounded to a protective earth (PE) for

safetypurposes.

The earth or ground connection must comply with the local

regulations.Forgrounding,use cableswithcrosssectionsas

Notes:

(1)

First environment: includes domestic premises. It also

includes establishments directly connected without

intermediatetransformers to alow-voltagepower supply

network which supplies buildings used for domestic

purposes.

(2)

Second environment: includes all establishments other

than those directly connected to a low-voltage power

supplynetworkwhichsuppliesbuildingsusedfordomestic

purposes.

(3)

Unrestricted distribution: mode of sales distribution in

which the supply of equipment is not dependent on the

EMC competence of the customer or user for the

applicationof drives.

(4)

Restricteddistribution:mode ofsalesdistributioninwhich

the manufacturer restricts the supply of equipment to

suppliers, customers or users who separately or jointly

have technical competence in the EMC requirements of

theapplicationofdrives.

KeypadOperation

All functions relating to the CFW-08 operation (Start/Stop,

Direction of Rotation, JOG, Increment/Decrement, Speed

(Frequency) Reference,andselectionofLocal/Remotemode)

canbe performedthroughthe HMIselection.

Forfactorydefaultprogrammingoftheinverter, allkeypadkeys

areenabledwhenthe Local mode has been selected.

Thesesame functions can be performed through digital and

analoginputs.Thusyoumustprogramtheparametersrelated

tothese correspondinginputs.

NOTE!

The control keys , and are only enabled if:

P229 = 0 for Local mode operation.

P230 = 0 for Remotemode operation.

The key depends of the parameters aboveand if:

P231 = 2.

Parameter Viewing and

Programming

All CFW-08 settings are made through parameters. The

parameter are shown on the display by the letter

followed

bya number:

Example(P101):

101 = Parameter Number

Each parameter is associated with a numerical value

(parameter value), that corresponds to the selected option

amongtheavailableonesforthisparameter.

Theparametervalues definethe inverterprogrammingor the

value of a variable (e.g.: current, frequency,voltage).For in-

verter programming you should change the parameter

content(s).

Ifduringtherunningof theSelf-Tuning Routinethedisplay

this means that the motor parameters were

not acquired correctly by the inverter.The most common

reason for this fault maybe that the motor has not been

coupled to the inverter output. However motors withvery

lower currents than the used inverter, or incorrect motor

connection may also cause the fault E14. In this case,

operate the inverter in V/F mode (P202 = 0). When the

Switchoff theinverter. Wait at least10minutesto allow

This section describes the main concepts related to the

CFW-08

frequencyinverter.

As already informed in

item

2.3, CFW-08 has in the same

producta V/Fcontrol and a sensorlessvector control(VVC:

“voltage vector control”).

The user must choose one of them. Please find below a

description of each control mode.

This control mode is based on the constant V/F curve

(P202= 0 - linear V/Fcurve).Itsperformanceislimitedat low

frequencies as function of the voltage drop in the stator

resistance,that causes a significant magnetic flow reduction

in the motor air gap and consequently reducing the motor

torque. This deficiency should be compensated by using

manualandautomaticboosttorque(IxRcompensations),that

are set according to the parameters P136 or P137.

Inmostapplications(forinstance:centrifugalpumpsandfans)

thesetting ofthesefunctionsisenoughto obtain therequired

performance. But there

areapplicationsthat require a more

sophisticatedcontrol.Inthesecases

it'srecommendedtheuse

of the sensorless vector control, that will be describedin the

item 6.2.3 - VectorControl(VVC).

CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

6.2.3

VectorControl (VVC)

InV/F control, the speed regulation, that can be obtained by

settingproperlyslip compensationcan be maintained within

1 % to 2 % of the rated speed. For instance, for a IV pole

motor/60Hz,theminimumspeedvariationatnoloadcondition

andat rated loadcanbemaintainedbetween18 and 36 rpm.

Thereis still avariationof thelinearV/F control:the quadratic

V/Fcontrol.Thiscontrolmode is suitableforapplicationslike

centrifugal pumps and fans (loads with quadratic torque x

speedcharacteristics),sinceitenablesa motorlossreduction,

resultingin an additional energysaving by using an inverter.

Formore details about the V/F control mode, please referto

the description of the parameters P136, P137, P138, P142

and P145.

Inthe sensorless vectorcontrol availableattheCFW-08,the

inverter operation is optimized for the used motor, so that a

better performance in terms of torque and speed regulation

is obtained. This vector control does not require a signal of

the speed feedback through tachogenerator or encoder

coupledon motorshaft.

To maintain the magnetic flux in the motor air gap constant,

and consequently the motor torque, within the whole speed

variationrange(fromzerouptothefield weakening point),a

sophisticated control algorithm is used that considers the

mathematicmodel of the inductionmotor.

Thusone canmaintainthe magnetic flux in the motor air gap

approximatelyconstantatfrequenciesdowntoapproximately

1Hz.

In vector control mode one can obtain a speed regulation of

0.5% (relatingtotheratedspeed).Thus,for instance,foraIV

polemotor/60Hzonecan obtainaspeedvariationin the ran-

ge of 10 rpm.

Other advantage of the vector control is its easy setting

procedure. The user needs only to enter in the parameters

P399 and P407 the information about the used motor

(nameplatedata)andruns theself-tuning routine (bysetting

P408 = 1) and the inverter configures itself to the required

application. So the inverter is ready to be operated in an

optimizedmanner.

ParameterP145 definestherated frequency of the mo-

torused.

The V/F curve relates the inverter output voltage and

frequency (applied to the motor) and consequently the

magnetizingfluxofthemotor.

The programmable V/F curve can be used in special

applications where the motors used require a rated

voltageand/orfrequency

different than the standard

ones.Examples:motorfor 220V/400 Hzanda motorfor

200V/60 Hz.

Parameter P142 is also useful in appplications that

require motor rated voltage different from the inverter

supplyvoltage.Example: 440Vline and 380 V motor.
