■High voltage warning

The voltage of the frequency converter is dangerous whenever the converter

is connected to mains. Incorrect fitting of the motor or frequency converter may cause damage to the equipment, serious injury or death. Consequently, it is essential to com ply with the instructions in this manual as well as local and national rules and safety regulations.

■These rules concern your safety

1. The frequency converter must be disconnected

from the mains if repair work is to be carried out. Check that the mains supply has been disconnected and that the prescribed time has passed before removing motor and mains plugs.

2. The [STOP/RESET] key on the control panel of

the frequency converter the equipment from mains and is thus n to be used as a safety switch.

3. The unit must be properly connected to the

earth, the user must be protected against the supply voltage and the motor must be protected against overloading pursuant to prevailing national and local regulations.

4. The earth leakage currents are higher than 3.5 mA.

5. Protection against motor overload is not included

in the factory setting. If this function is required, set parameter 128 Motor thermal protection to data value ETR trip or data value ETR warning.For the North American market: The ETR functions provide overload protection of the motor, class 20, in accordance with N EC.

does not disconnect

ensure that no unintended start occurs, stop functions are not sufficient.

2. While parameters are being changed, the motor may start. Consequently, t [STOP/RESET] must always be activated, following which data can be modified.

3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload or a f ault in the supply mains or the motor connection ceases.

■Use on isolated mains

See section RFI Switch regarding use on isolated mains.

It is important to follow the recommendations regarding installation on IT-mains, since sufficient protection of the complete installation must be observed. Not taking care using relevant monitoring devices for IT-mains may result in damage.

■Technology

■Control principle

A frequency converter rectifies AC voltage from the mains supply into DC voltage, following which it changes this v oltage to an AC voltage with variable amplitude and frequency. The motor thus receives a variable voltage and frequency, which enables infinitely variable speed control of three-phase, standard AC motors.

■VLT 2800 control principle

A frequency converter is an electronic unit which is able to infinitely vari ab ly control the rpm of an AC motor. The frequency converter governs the motor speed by converting the regular voltage and frequency from mains, e.g. 400 V / 50 Hz, into variable magnitudes. Today the frequency converter controlled AC motor is a natural part of all types of automated plan ts. The frequency converter has an inverter control system called VVC (Voltage Vector Control). VVC controls an induction motor by energizing with a variable frequency and a voltage suitable for it. If the motor load changes, so do its energizing and speed. That is why the motor current is measured on an ongoing basis, and a motor model is used to calculate the actual voltage requirement and slip o f the motor.

■Programmable inputs and outputs in four Setups

In the frequency converter is possible to program the different control inputs and signal outputs and to select four different user-defined Setups for most parameters. It is easy for the user to p rogram the required functions on the control panel or via serial c ommunication.

. Intermediate circuit

DC voltage √2 x mains voltage [V].

. Intermediate circuit coils Evens out the intermediate circuit current and limits the load on mains and components (mains transformer, cables, fuses and contactors).

. Intermediate circuit condenser

5 Evens out the intermediate circuit voltage.

. Inverter Converts DC voltage into a variable AC voltage withavariablefrequency.

. Motor voltage

7 Variable AC voltage d e pe nding on supply voltage. Variable frequency: 0.2 - 132 / 1 - 1000 Hz.

. Control card Here is the computer that controls the inverter which generates the pulse pattern by which the DC voltage is converted into variable AC voltage with a variable frequency.

■Mains protector

The frequency converter is protected against the transients that occur on the mains sometimes, e.g. if coupling with a phase compensation system, or if fuses blow when lightning strikes.

Rated motor voltage and full torque can be maintained down to approx. 10% undervoltage in the mains supply.

As all 400 V units in the VLT 2800 Series have intermediate circuit coils, there is only a low amount of harmonic mains supply interference. This gives a good power factor (lower peak current), which reduces the load on the mains installation.

■Frequency converter protections

The current measurement in the intermediate circuit constitutes perfect protection of the frequency in case there is a short-circuit or an earth fault on the motor connection. Constant monitoring of the intermediate circuit current enables switching on the motor output, e.g. by means of a contactor. Efficient monitoring of the mains supply means that the unit will stop in the c ase of a phase drop-out. In this way, the inverter and the condensers in the intermediate

MG.28.E9.02 - VLT is a registered Danfoss trademark

circuit are not overloaded, which would dramatically reduce the service life of the frequency converter. The frequency converter offers temperature protection as standard. If there is a thermal overload, this function cuts out the inverter.

■Reliable galvanic isolation

In the frequency converter all digital inputs/outputs, analogue inputs/outputs and the terminals for serial communication are supplied from or in connection with circuits that comply with PELV requirements. PELV is also complied with in relation to relay terminals, so that they can be connected to the mains potential. For further information see the section entitled Galvanic Isolation (PELV).

■Advanced motor protection

The frequency converter has integral electronic motor protection. The frequency converter calculates the motor temperature on the basis of current, frequency and time. As opposed to traditional, bimetallic protection, electronic protection takes account of reduced cooling at low frequencies because of reduced fan speed (motors with internal fan). This function cannot protect the individual motors when motors are connected in parallel. Thermal motor protection can be compared to a protective motor switch, CTI. To give the motor maximum protection against overheating when it is covered or blocked, or if the fan should fail, you can install a thermistor and connect it

to the frequency converter’s thermistor input (Digital

input), see parameter 128 Thermal motor protection.

■CE labelling

What is CE labelling?

The p urp ose of CE labelling is to avoid technical obstacles to trade within EFTA and the EU. The EU has introduced the CE label as a simple way of showing whether a product complies with the relevant EU directives. The CE label says nothing about the specifications or quality of the product. Frequency converters are regulated by three EU directives:

The machinery directive (98/37/EEC)

All machines with critical moving parts are covered by the machinery direct ive, which came into force on 1 January 1995. Since a frequency converter is largely electrical, it does not fall under the machinery directive. However, if a frequency converter is supplied for use in a machine, we provide information on safety aspects relating to the frequency converter. We do

this by means of a manufacturer’sdeclaration.

The low-voltage directive (73/23/EEC)

Frequency converters must be CE labe lled in accordance with the low-voltage directive, which came into force on 1 January 1997. The directive applies to all electrical equipment and appliances used in the 50 - 1000 Volt AC and the 75 1500 Volt DC voltage ranges. Danfoss CE labels in accordance with the directive and issues a declaration of conformity upon request.

The EMC directive (89/336/EEC)

EMC is short for electromagnetic compatibility. The presence of electromagnetic compat ibility means that the mutual i nterference between different components/appliances is so small that the functioning of the appliances is not affected. The EMC directive came into force on 1 January 1996. Danfoss CE labels in accordance with the directive and issues a declaration of conformity upon request. In order that EMC-correct installation can be carried out, this manual gives detailed instructions for installation. In addition, we specify the standards w hich our different products comply with. We offe r the filters that can be seen from the specifications and provide other types of assistance to ensure the optimum EMC result.

VLT®2800 Series

In the great majority of cases, the frequency converter is used by professionals of the trade as a complex component forming part of a larger appliance, system or installation. It must be noted that the responsibility for the final EM C properties of the appliance, system or installation rests with the installer.

■Harmonic filter

The harmonic currents do not affect power consumption directly, but they increase the heat losses in the installation (transformer, cables). That is why, in a system with a relatively high percentage of rectifier load, it is important to keep the harmonic currents at a low level so as to avoid a transformer overload and high cable temperature. For the purpose of ensuring low harmonic currents, VLT 2822-2840 3 x 200-240 V and VLT 2805-2882 380-480 V are fitted with coils in their intermediate circuit as standard. This reduces the input current I Please note that 1 x 220-240 V units are not supplied with coils in their intermediate circuit.

■FC protocol

Danfoss frequency converters are able to fulfill many different functions in a monitoring system. The frequency converter can be integrated directly in an overall surveillance system, which will allow detailed process data to be transferred via serial communication.

Introduction to VLT

MG.28.E9.02 - VLT is a registered Danfoss trademark

■Dynamic braking

With the VLT 2800 the dynamic braking quality in an application can be improved in two ways, either with the aid of brake resistors or AC braking.

Danfoss offers a complete range of brake resistors for all VLT 2800 frequency converters. It is the job of the brake resistor to apply a load to the intermediate circuit during braking, thereby ensuring that the brake power can be absorbed by the brake resistor. Without a brake resistor, the intermediate circuit voltage of the frequency converter would go on rising, until cutting out for protection. The advantage of using a brake resistor is that you can brake quickly with large loads, e.g. on a conveyor belt.

Danfoss has chosen a solution in which the brake resistor is not integrated into the frequency converter. This gives the user the following advantages:

-Theresistor’s cycle time can be selected as required.

- The heat generated during braking can be

diverted outside the panel cabinet, where the energy can possibly be utilised.

- No overhea ting of the e lectronic components,

even if the brake resistor is overloaded.

VLT®2800 Series

■Calculation of brake resistance

The following example and formula only apply to VLT 2800 Series. To ensure that the frequency converter does not cut out for safety reasons when the motor brakes, the resistance value is selected on the basis of the peak braking effec t and the intermediate circuit voltage:

AC braking is an integrated function that is used for applications in which there is a need for limited dynamic braking. The AC braking function makes it possible to reduce the brake power in the motor instead of in a brake resistor. The function is intended for applicati ons where the required braking torque is less than 50% of rated torque. AC braking is selected in par. 400 Brake function.

NB!:

The AC brake cannot be used if the required braking torque is more than 50% of rated braking torque. In such instances

a brake resistor must be used.

■Brake Setup

ThefigureshowsabrakeSetupwitha frequency converter. In the following paragraphs, expressions and acronyms are used about brake Setups that can be seen from the figure.

It can be seen that the brake resistance depends on the intermediate circuit voltage (UDC). With frequency converters that have a mains voltage of 3 x 380 - 480 Volt, the brake will be active at 770 Volt (UDC); if the frequency converter has a mains voltage of 3 x 200 - 240 Volt, the brake will be active at 385 Volt (UDC). You can also choose to use the brake resistance recommended by Danfoss (R guarantee that the frequency converter brakeatthehighestbrakingtorque(M

recommended brake resistance can be seen from the ordering table for brake resi

NB!:

Remember to check that the brake resistance can manage a voltage of 850 Volt or 430 Volt, if Danfoss brake resistors are not being used.

NB!:

The brake resistance selected should have an ohmic value no more than 10% lower

than that recommended by Danfoss. I lower brake resistance is selected there is a risk of overcurrent, which can destroy the unit.

■Calculation of braking power

When calculating the braking pow er, it must be ensured that the mean and pe ak powers can be dissipated to the brake resistor. The mean power is determined by the period time of the process, i.e. for how long the brake is applied in relation to the period time of the process. The peak power is determined by the braking torque, which means that during braking the brake resistor must be able to dissipate the energy input. The figure shows the relation between mean power and peak power.

of the motor and the frequency converter. The peak effect is calculated as follows:

If you select Danfoss’ recommended braking resistor

), you are certain that the braking resistance can

generate a braking torque of 160% on the m otor shaft.

■Calculation of mean power on brake resistor

The mean power is determined by the period of the process, i.e. how long you brake in relation to the period of the process. Duty-cycle for braking is calculated as follows:

Tp= The process time in seconds.

= The braking time in seconds.

Danfoss sells brake resistors with variable duty-cycles up to 40%. For example, with a 10% duty-cycle, brake resistors can take up P

in 10% of the

peak

process period. The remaining 90% of the period time is spent on redirecting surplus heat. The mean power at 10% duty cycle can be calculated as follows:

These calculations apply to intermittent braking with period times of up to 120 seconds.

NB!:

Period times longer than 120 sec. may lead to overheating of the resistor.

■Continuous braking

For continuous braking, a brake resistor should be selected in which the constant braking power does not exceed the mean power P

of the brake resistor.

■D.C. injection braking

If the three-phase winding of the stator is fed with direct current, a stationary magnetic field will be set up in the stator bore causing a voltage to be induced in the bars of the cage rotor as long as the rotor is in motion. Since the electrical resistance of the rotor cage is very low, even small induced voltages can create a high rotor current. This current will produce a strong braking effect on the bars and hence on the rotor. As the speed falls, the frequency of the induced voltage falls and with it the inductive impedance. The ohmic resistance of the rotor gradually becomes dominant and so increases the braking effect as the speed comes down. The braking torque generated falls away steeply just before standstill and finally ceases when there is no further movement. Direct current injection braking is therefore not suitable for actually holding a load at rest.

■AC-braking

When the motor acts as a brake the DC-link voltage will increase because energy is fed back to the DC-link. The principle in AC-brake is to increase the magnetisation during the braking and thereby increase the thermal losses of the motor. Using par. 144 in VLT 2800 it is possible to adjust the size of the generator torque that can be applied to the motor without the intermediate circuit voltage exceeding the warning level.

The braking torque depends on the speed. With the AC-brake function enabled and parameter 144 = 1,3 (factory setting) it is possible to brake with about 50 % of rated torque below 2/3 of rated speed and with about 25 % at rated speed. The function is not working at low speed (below 1/3 of nominal motor speed). It is only possible to run for about 30 seconds with pa rameter 144 greater than 1.2.

NB!:

If the value in parameter 144 is increased,

the motor current will simultaneously increase

significantly when generator loads are applied. The parameter should therefore only be changed if it is guaranteed during measurement that the motor current in all operating situations will never exceed the maximum permitted current in the motor. Please note: The current can not be read out from the display.

DC braking is to be applied a s required. The most efficient way of doing this is by using a combinat ion of dynamic and DC braking. See the illustration.

NB!:

When changing from dynamic to DC braking, there will be a short period (2-6 milliseconds) with very low braking torque.

■Brake cable

Max. length [m]: 20 m The connection cable to the brake resistor must be screened/armoured. Connect the screen totheconductivebackplateatthefrequency converter and to the brake resistor metal cabinet by means of cable clamps.

NB!:

If D anfoss brake resistors are not used, it must be ensured that the brake resistor is induction-free.

■Optimal braking using resistor

Dynamic braking is useful from maximum speed down to a certain frequency. Below this frequency

■Protective functions during installation

When a brake resistor is installed, the best possible endeavors should be made to avoid overloads, as the heat generating from a brake resistor may involve a fire risk.

NB!:

The brake resistor should be fitted to a

nonflammable material.

For p rotection of the installation, a thermal relay should be fitted that cuts off the frequency converter if the brake current becomes too high. Flat pack resistors are self-protecting.

Calculate the brake current setting of the thermal relay as follows:

Itherm relay =

Rbris the current brake resistor value calculated in the section on "Calc ulation of brake resistance". The figure shows an installation with a thermal relay.

The brake current setting of thermal relay for Danfoss 40% brakeresistors can be found in the table further on.

Introduction to VLT

Some of the Danfoss Brakeresistors contain a thermal switch (see table further on). This switch is NC (normally closed) and can be used e.g. coasting stop reverse between terminal 12 and 27. The drive will then coast, if the thermal switch is opened.

NB!:

The thermal switch is not a protective

device. For protection, use a thermal

switch as shown in the figure.

■Control unit

On the front of the frequency converter there is a control panel.

The control panel is divided into four function groups:

1. Six-digit LED display.

2. Keys for changing parameters and shifting

display function.

3. Indicator lamps.

4. Keys for local operation.

All displays of data are in the form of a six-digit LED display capable of showing one item of operating data continuously during normal operation. As a supplement to the display, there are three indicator lamps for indicat ion of mains connection (ON), warning (WARNING) and alarm (ALARM). Most of

the frequency converter’s parameter Setups can be

changed immediately via the control panel, unless this function has been programmed as Locked [1] via parameter 018 Lock for data changes.

These keys are also used in Display mode for selecting the display of an operating value.

The [QUICK MENU] + [+] keys must be

pressed at the same time to give access to all parameters. See Menu mode.

[STOP/RESET] is used for stopping the

connected motor or for resetting the frequency converter after a trip. Can be selected as Active [1] or Not active [0] via parameter 014 Local stop/reset. In Display mode, the display will flash if the stop function is ac tivated.

NB!:

If the [STOP/RESET] key is set at Not active [0] in parameter 014 Loca l stop/reset,and

there is no stop command via the digital inputs or serial communication, the motor can only be stopped by disconnecting the mains voltage to the frequency converter.

[START] is used for starting the frequency

converter. It is always active, but the [START] key cannot override a stop command.

■Manual initialisation

Disconnect mains voltage. Hold the [QUICK MENU] + [+] + [CHANGE DATA] keys down while simultaneously reconnecting the mains voltage. Release the keys; the frequency converter has now been programmed for the factory setting.

■Control keys

[QUICK MENU] allows access to the parameters

used for the Quick menu. The[QUICK MENU] key is also used if a change to a parameter value is not to be implemented. See also [QUICK MENU] + [+].

[CHANGE DATA] is used for changing a setting.

The [CHANGE DATA] key is also used for confirming a change of parameter settings.

[+] / [-] are used for selecting parameters and

for changing parameter values.
