Setting the value = 0 gives you a linear ramp shape. The output frequency

immediately follows the input with a ramp time set by parameters 1.3, 1.4 (4.3,4.

Setting 0.1-l 0 seconds for 4. 1

These values correspond to the time required for the output frequency to change

2). With this parameter it is possibile to set two different acceleration/deceleration

times for one application. The active set can be selected with the programmable

signal DIA3. See parameter 2.2.

Brake chopper

0 = No

brake chopper

1 = Brake chopper and brake resistor installed

2 = External brake chopper

When the drive is decelerating the motor, the energy stored in the inertia of the

motor and the load is fed into the external brake resistor. If the brake resistor is

selected correctly the drive is able to decelerate the load with a torque equal to

that of acceleration. See the separate Brake resistor installation manual.

4.6

Start function

Ramp:

The drive starts from 0 Hz and accelerates to the set reference frequency within

the set acceleration time. (Load inertia or starting friction may extend the

acceleration times).

Page 1-18

Standard Application

Flying start:

HV9090

The drive starts into a running motor by first finding the speed the motor is

running at. Searching starts from the maximum frequency down until the actual

frequency reached. The output frequency then accelerates/decelerates to the

set reference value at a rate determined by the acceleration/deceleration ramp

parameters.

Use this mode if the motor may be coasting when the start command is given.

With the flying start it is possible to ride through short utility voltage interruptions.

4.8

DC braking

Defines the current injected into the motor during DC braking.

4.9

DC braking time at stop

Determines whether DC braking is ON or OFF. It also determines the braking duration

time of the DC-brake when the motor is stopping. The function of the DC-brake

depends on the stop function, parameter 4.7. See figure 1.5-13.

DC-brake is not used

DC-brake is in use depending on the setup of the stop function

(param. 4. 7). The time is set by the value of parameter 4. 9:

= 0 (coasting): Stop-function

After the stop command, the motor will coast to a stop with the HV9000 off.

With DC-injection, the motor can be electrically stopped in the shortest possible

time, without using an optional external braking resistor.

The braking time is scaled according to the frequency when the DC- braking

starts. If the frequency is 2 nominal frequency of the motor (par. 1 .ll), the value

of parameter 4.9 determines the braking time. When the frequency is 5 10% of

the nominal, the braking time is 10% of the set value of parameter 4.9. See figure

1.5-l 3.

In some systems it may be

necessary to avoid certain

frequencies because of

mechanical resonance problems.

With these parameters it is

possible to set limits for one “skip

frequency” region between 0 Hz

and 120 Hz/500 Hz. Accuracy of

the setting is 0.1 Hz.

HV9000

6.1

The I/O terminal and panel references are frequency ref-

erences and the drive controls the output frequency (out-

put freq. resolution 0.01 Hz)

The I/O terminal and panel references are speed refer-

ences and the drive controls the motor speed (control

accuracy + 0.5%).

6.2

Switching frequency

Motor noise can be minimized by using a high switching frequency. Increasing the

switching frequency reduces the current capacity of the HV9000.

Before changing the frequency from the factory default 10 kHz (3.6 kHzA40 Hp)

check the drive derating in the curves shown in figures 5.2-2 and 5.2-3 in chapter

5.2 of the User’s Manual.

6.3

Field weakening point

Voltage at the field weakening point

The field weakening point is the output frequency where the output voltage reaches

the set maximum value (parameter 6. 4). Above that frequency the output voltage

remains constant at the set maximum value. Below that frequency the output voltage

depends on the setting of the V/Hz curve parameters 1. 8, 1. 9, 6. 5, 6. 6 and 6. 7.

See figure 1.5-16.

When the parameters 1. 10 and 1. 11, nominal voltage and nominal frequency of

the motor, are set, parameters 6.3 and 6. 4 are also set automatically to the same

values. If you need different values for the field weakening point and the maximum

output voltage, change these parameters after setting parameters 1. 10 and 1. 11.

6.4

6.5

V/Hz curve, middle point frequency

If the programmable V/Hz curve has been selected with parameter 1.8, this parameter

defines the middle frequency point of the curve. See figure 1.5-16.

6.6 V/Hz curve, middle point voltage

If the programmable V/Hz curve has been selected with parameter 1.8, this parameter

defines the middle voltage point of the curve. See figure 1.5-16.

6.7

Output voltage at zero frequency

If the programmable V/Hz curve has been selected with parameter 1. 8, this

parameter defines the zero frequency voltage of the curve. See figure 1.5-16.

Overvoltage

Undervoltage

controller

These parameters allow the over/undervoltage controllers to be switched ON or OFF.

This may be useful in cases where the utility supply voltage varies more than -15%-

+10% and the application requires a constant speed. If the controllers are ON, they

will change the motor speed in over/undervoltage cases. Overvoltage = faster,

undervoltage = slower.

Over/undervoltage trips may occur when the controllers are not used.

A warning or a fault action and message is generated if the 4-20 mA reference

Ground fault protection ensures that the sum of motor phase currents is zero. The

standard overcurrent protection is always present and protects the drive from ground

faults with high current levels.

7.5 Motor thermal protection

Operation:

0 = Not in use

1 = Warning

2 = Trip

The motor thermal protection protects the motor from overheating. In the

Standard application the thermal protection has fixed settings. In other

applications it is possible to set the thermal protection parameters. A trip or a

warning will give an indication on the display. If trip is selected, the drive will stop

the motor and generate a fault.

Deactivating the protection by setting the parameter to 0 will reset the internal thermal

model to 0% heating.

The HV9000 is capable of providing

higher than nominal current to the

motor. If the load requires this high

current there is a risk that motor will

be thermally overloaded. This is

true especially at low frequencies.

With low frequencies the cooling

effect of the motor fan is reduced

and the capacity of the motor is

reduced. Motor thermal protection

is based on a calculated model and

it uses the output current of the

drive to determine the load on the

motor.

Overload area

35 Hz

f WI

“UC”, ia

The thermal current Ir specifies

Figure 1.5- 17

Motor thermal current IT curve

the load current above which the

motor is overloaded. See figure

1.5-17. If the motor current is over the curve the motor temperature is increasing.

CAUTION! The calculated model does not protect the motor if the cooling of

the motor is reduced either by blocking the airflow or due to dust

or dirt.

Stall protection

Operation:

0 = Not in use

1 = Warning

2 = Trip function

The Motor Stall protection provides a warning or a fault based on a short time overload

of the stalled shaft. The stall protection is faster than the motor thermal

protection. The stall state is defined with Stall Current and Stall Frequency. In the

Standard application they both have fixed values. See figure 1.5-l 8. If the current is

higher than the set limit and output frequency is lower than the set limit the stall

state is true. If the stall lasts longer than 15 s a stall warning is given on the display

panel. In the other applications it is possible to set the parameters of the Stall

protection function. Tripping and warning will give a display indication. If tripping is

set on, the drive will stop and generate a fault.

Deactivating the stall protection by

Parameter 8. 1 determines how many automatic restarts can be made during the

trial time set by the parameter 8.2.

The count time starts from the first autorestart. If the number of restarts does not

exceed the value of the parameter 8.1 during the trial time, the count is cleared after

the trial time has elapsed. The next fault starts the counting again.

2.1 General

By utilizing

the Local/Remote Control

Application, the use of two different control

and frequency reference sources is

programmable. The active control source is

selected with digital input DIB6.

The Local/Remote Control Application can be

activated from the Group 0 by setting the value

of parameter 0. 1 to 3.

Basic connections of inputs and outputs are

shown in the figure 2.2-l. The control signal

logic is shown in the figure 2.3-l. Programming

of l/O terminals is explained in chapter 2.5,

Squared:

The voltage of the motor changes following a squared curve form

with the frequency in the area from 0 Hz to the field weakening

1 point (par. 6. 3) where the nominal maximum voltage is supplied to

the motor. See figure 2.4-1.

The motor runs undermagnetized below the field weakening point

and produces less torque and electromechanical noise. A squared

V/Hz ratio can be used in applications where the torque demand of

the load is proportional to the square of the speed, e.g. in centrifugal

fans and pumps.

Automatic

torque

boost

The voltage to the motor changes automatically which allows the

motor to produce torque enough to start and run at low frequencies.

The voltage increase depends on the motor type and horsepower.

Automatic torque boost can be used in applications where starting

torque due to starting friction is high, e.g. in conveyors.

NOTE!

In high torque - low speed applications

it is &e/y the motor wi// overheat.

If the motor has to run for a prolonged time under these conditions, special

attention must be paid to cooling of the motor. Use external cooling for

the motor if the temperature rise is too high.

times for one application. The active set can be selected with the programmable

with a free analog input signal. See parameters 2. 18 and 2. 19.

When the drive is decelerating the motor,

correctly the drive is able to decelerate the load with a torque equal to that of

acceleration, See the separate Brake resistor installation manual.

4.6

Start function

Ramp:

The drive starts from 0 Hz and accelerates to the set reference frequency within

the set acceleration time. (Load inertia or starting friction may cause prolonged

acceleration times).

HV9000

Local/Remote Control Application

Page 2-27

Flying start:

1 The drive starts into a running motor by first finding the speed the motor is

running at. Searching starts from the maximum frequency down until the actual

frequency reached. The output frequency then accelerates/decelerates to the

set reference value at a rate determined by the acceleration/deceleration ramp

parameters.

Use this mode if the motor may be coasting when the start command is given.

With the flying start it is possible to ride through short utility voltage interruptions.

4.7

Stop function

Coasting:

The motor coasts to an uncontrolled stop with the HV9000 off, after the Stop

command.

Ramp:

1 After the Stop command, the speed of the motor is decelerated based on

the deceleration ramp time parameter.

If the regenerated energy is high, it may be necessary to use an external

braking resistor for faster deceleration.

4.8

braking current

Defines the current injected into the motor during DC braking.

The DC braking current can be reduced from the setpoint with a external free

analog input signal, see parameters 2. 18 and 2. 19.

4.9

braking time at stop

Determines whether DC braking is ON or OFF. It also determines the braking duration

time of the DC-brake when the motor is stopping. The function of the DC-brake

depends on the stop function, parameter 4.7. See figure 2.5-23.

DC-brake is not used

DC-brake is in use and its function depends of the stop function,

(parameter 4. 7), The time is set by the value of parameter 4. 9:

Stoo-function = 0 (coastina):

After the stop command, the motor will coast to a stop with the HV9000 off.

With DC-injection, the motor can be electrically stopped in the shortest possible

time, without using an optional external braking resistor.

The braking time is scaled according to the frequency when the DC- braking

starts. If the frequency is 2 nominal frequency of the motor (par. 1 .l l), the value

of parameter 4.9 determines the braking time. When the frequency is c 10%

of the nominal, the braking time is 10% of the set value of parameter 4.9. See

figure 2.5-13.

Stop-function = 1 (ramp):

After a Stop command, the speed of the motor is reduced based on the

deceleration ramp parameter. If no regeneration occurs due to load inertia DC-

braking starts at a speed defined by parameter 4. 10.

Field weakening point

Voltage at the field weakening point

The field weakening point is the output frequency where the output voltage reaches

the set maximum value (parameter 6. 4). Above that frequency the output voltage

remains constant at the set maximum value. Below that frequency the output voltage

depends on the setting of the V/Hz curve parameters 1.8, 1.9, 6.5,6.6 and 6.7.

See figure 1.5-l 8.

When the parameters 1.10 and 1.11, nominal voltage and nominal frequency of the

motor, are set, parameters 6.3 and 6.4 are also set automatically to the same values.

If you need different values for the field weakening point and the maximum output

voltage, change these parameters after setting parameters 1. 10 and 1. 11.

7.3

Phase supervision

0 = No action

2 = Fault

Phase supervision of the motor ensures that the motor phases have approximately

equal current.

7.4 Ground fault protection

0 = No action

2 = Fault message

Ground fault protection ensures that the sum of the motor phase currents is zero.

The standard overcurrent protection is always present and protects the frequency

converter from ground faults with high current levels.

Parameters 7.5-7.9 Motor thermal protection

of the motor

General

Motor thermal protection protects the motor from overheating. The HV9000 drive is

capable of supplying higher than nominal current to the motor. If the load requires

this high current there is a risk that motor will be thermally overloaded. This is true

especially at low frequencies. With low frequencies the cooling effect of the motor

fan is reduced and the capacity of the motor is reduced. If the motor is equipped

with a separately powered external fan, the load derating at low speed is small.

Motor thermal protection is based on a calculated model and it uses the output cur-

rent of the drive to determine the load on the motor. When the motor is powered

from the drive, the calculated model uses the heatsink temperature to determine

the initial thermal state of the motor. The calculated model assumes that the ambi-

ent temperature of the motor is 40°C.

Motor thermal protection can be adjusted by setting several parameters. The thermal

current IT specifies the load current above which the motor is overloaded. This cur-

rent level is a function of the output frequency. The curve for IT is set with param-

eters 7.6, 7. 7 and 7. 9. See figure 2.5-28. The default values of these parameters

are set from the motor nameplate data.

With the output current at IT the thermal state will reach the nominal value (100%).

The thermal state changes by the square of the current. With output current at 75%

of IT the thermal state will reach 56% and with output current at 120% of $ the thermal

stage would reach 144%. The function will trip the drive (refer par. 7.5) If the thermal

state reaches a value of 105%. The response time of the thermal model is deter-

mined by the time constant parameter 7.8. The larger the motor, the longer it takes

to reach the final temperature.

Page 2-32

Local/Remote Control Application

HV9000

The thermal state of the motor can be monitored through the display. Refer to the

table for monitoring items. (User’s Manual, table 7.3-l).

CAUTION!

The calculated mode/ does not protect the motor if the cooling of

the motor is reduced either by blocking the airflow or due to dust or

dirt.

7. 5 Motor thermal protection

Operation:

0 = Not in use

1 = Warning

2 = Trip function

Tripping and warning will give a display indication with the same message code. If

tripping is selected the drive will stop and activate the fault stage.

Deactivating the protection by setting this parameter to 0, will reset the thermal stage

of the motor to 0%.

7.6 Motor thermal protection, break point current

This current can be set between 50.0-150.0% x InMatar.

This parameter sets the value for thermal current at frequencies above the break

point on the thermal current curve. Refer to the figure 2.5-28.

The value is set as a percentage of the motor nameplate nominal current, parameter

1. 13, not the drive’s nominal output current.

The motor’s nominal current is the current which the motor can withstand in direct

online use without being overheated.

If parameter 1. 13 is adjusted, this parameter is automatically restored to the default

value.

Setting this parameter (or

parameter 1. 13) does not affect

the maximum output current of the

drive. Parameter 1.7 alone

determines the maximum output

current of the drive.

Motor thermal protection, zero frequency current

This parameter sets the value for thermal current at zero frequency. Refer to the

The default value is set assuming that there is no external fan cooling the motor. If

an external fan is used this parameter can be set to 90% (or higher).

The value is set as a percentage of the motor’s nominal nameplate current,

parameter 1.13, not the drive’s nominal output current. The motor’s nominal current

is the current which the motor can stand in direct on-line use without being

overheated.

If you change parameter 1.13, this parameter is automatically restored to the default

value.

Setting this parameter (or parameter 1. 13) does not affect to the maximum output

current of the drive. Parameter 1.7 alone determines the maximum outout current

of the drive.

7.8

Motor thermal protection, time constant

This time can be set between 0.5-300 minutes.

This is the thermal time constant of the motor. The larger the motor the greater

the time constant. The time constant is defined as the time that it takes the calcu-

lated thermal stage to reach 63% of its final value.

The motor thermal time is specific to a motor design and it varies between different

motor manufacturers.

The default value for the time constant is calculated based on the motor

nameplate data from parameters 1. 12 and 1. 13. If either of these parameters is

reset, then this parameter is set to default value.

If the motor’s t6 -time is known (given by the motor manufacturer) the time

constant parameter could be set based on ts -time. As a rule of thumb, the motor

thermal time constant in minutes equals to 2xts (t6 in seconds is the time a motor

can safely operate at six times the rated current). If the drive is stopped the time

constant is internally increased to three times the set parameter value. Cooling in

the stop stage is based on convection with an increased time constant

7.9

Motor thermal protection, break point frequency

This frequency can be set between 10-500 Hz.

This is the frequency break point of the thermal current curve. With frequencies

above this point the thermal capacity of the motor is assumed to be constant.

Refer to the figure 2.528.

The default value is based on the motor’s nameplate data, parameter 1. 11. It is 35

Hz for a 50 Hz motor and 42 Hz for a 60 Hz motor. More generally it is 70% of the

frequency at the field weakening point (parameter 6.3). Changing either parameter

1. 11 or 6.3, will restore this parameter to its default value.

Parameters 7.1 O- 7.13, Stall protection

General

Motor stall protection protects the motor from short time overload situations like a

stalled shaft. The reaction time of stall protection can be set shorter than with motor

thermal protection. The stall state is defined with two parameters, 7.11, Stall Current

and 7.13., Stall Frequency. If the current is higher than the set limit and output

frequency is lower than the set limit the stall state is true. There is no true detection

of rbtation. Stall protection is a type of overcurrent protection.

7.10

Stall protection

Operation:

0 = Not in use

1 = Warning

2 = Trip function

Tripping and warning will give a display indication with the same message code. If

tripping is set on, the drive will stop and generate a fault. Deactivating the stall

protection by setting the parameter to 0 will reset the stall time counter to zero.

7.11 Stall current limit

The current can be set between

o.O-200% x InMotor.

In a stall the current has to be

above this limit. See figure 2.5

30. The value is set as a

7.17, Underload protection

Page 2-35

The purpose of motor underload protection is to ensure there is a load on the motor

while the drive is running. If the motor load is reduced, there might be a problem in

the process, e.g. broken belt or dry pump.

Motor underload protection can be adjusted by setting the underload curve with

parameters 7.15 and 7. 16. The underload curve is a squared curve set between

zero frequency and the field weakening point. The protection is not active below

5Hz (the underload counter value is stopped). See figure 2.5-32.

The torque values for setting the underload curve are set with percentage values

which refer to the nominal torque of the motor. The motor’s nameplate data,

parameter 1 .13, the motor’s nominal current and the drive’s nominal current Icr

are used to create the scaling ratio for the internal torque value. If other than a

standard motor is used with the drive, the accuracy of the torque calculation is

decreased.

7.14

Underload protection

Operation:

0 = Not in use

1 = Warning message

2 = Fault message

Tripping and warning will give a display indication with the same message code. If

tripping is set active the drive will stop and activate the fault stage.

Deactivating the protection, by setting this parameter to 0, will reset the underload

time counter to zero.

7.15

Underload protection, field weakening area load

The torque limit can be set

between 20.0-l 50 % x TnMotor.

This parameter is the value for

the minimum allowed torque

3.4.2 Description of Group 1 parameters

1. 1, 1.2

Minimum/maximum frequency

Defines the frequency limits of the HV9000.

The default maximum value for parameters 1.1 and 1.2 is 120 Hz. By setting 1.2 =

120 Hz in the when the drive is stopped (RUN indicator not lit) parameters 1. 1 and

1.2 are changed to 500 Hz. At the same time the resolution of the panel reference is

changed from 0.01 Hz to 0.1 Hz.

Changing the max. value from 500 Hz to 120 Hz is done by setting parameter

1. 2 to 119 Hz while the drive is stopped.

1.3,l. 4 Acceleration time 1, deceleration time 1:

These limits correspond to the time required for the output frequency to

accelerate from the set minimum frequency (par. 1. 1) to the set maximum

frequency (par. 1. 2). Acceleration/deceleration times can be reduced with a free

analog input signal, see parameters 2. 18 and 2. 19.

which if it is programmed for Jog speed. See parameter 2. 2.

Parameter value is automatically limited between minimum and maximum frequency

(par 1.1,1.2)

1.7 Current limit

This parameter determines the maximum motor current that the HV9000 will provide

short term. Current limit can be set lower with a free analog input signal, see

parameters 2. 18 and 2. 19.

1.8 V/Hz ratio selection

Linear:

The voltage of the motor changes linearly with the frequency in

the constant flux area from 0 Hz to the field weakening point

(par. 6.3) where a constant voltage (nominal vaue) is supplied to

the motor. See figure 3.4-l.

A linear V/Hz ratio should be used in constant torque applications

This default setting should be used if there is no special

requirement for another setting.

Squared:

The voltage of the motor changes following a squared curve form

with the frequency in the area from 0 Hz to the field weakening

point (par. 6. 3), where the nominal voltage is supplied to

the motor. See figure 3.4-i.

The motor runs undermagnetized below the field weakening point and

produces less torque and electromechanical

noise. A squared V/Hz ratio

can be used in applications where the torque demand of the load is

proportional to the square of the speed, e.g. in centrifugal fans and

Speed Control Application

Page 3-7

The voltage to the motor changes automatically which

allows the motor to produce enough torque to start and

run at low frequencies. The voltage increase depends on the motor type

and horsepower. Automatic torque boost can be used in applications

where starting torque due to starting friction is high, e.g. in conveyors.

In high torque - low speed applications - it is likely the motor will

overheat.

If the motor has to run for a prolonged time under these conditions,

special attention must be paid to cooling the motor. Use external

cooling for the motor if the temperature rise is too high.
