Electrical safety
The frequency converter contains dangerous voltages when connected to the mains. Improper connection of the motor or frequency converter may cause equipment failure, serious in­jury or death.
Therefore follow the directions in this manual, as well as local and national safety codes.
Touching the electrical parts, even when the power supply has been switched off, can cause serious injury or death.
When using VLT® 3002-3052: Wait 4 minutes.
When using VLT® 3060-3250: Wait 14 minutes.
Warning
These rules concern your safety
1. When repairs are undertaken, the mains supply to the VLT
®
must be disconnected.
2. The “Stop/Reset” key on the frequency converter’s keyboard does not disconnect the power supply and may therefore not be used as a safety
switch.
3. The unit must be properly grounded, the user must be protected against supply voltage and the motor against overload according to national and local codes.
4. The leakage currents to ground are higher than 3 mA.
5. The factory setting does not incorpor- ate protection against motor overload. For this function parameter 315 is set at data value
“trip”
[2] or data value
“warning”
[1].
Note:
This function is initialised at 1.16 x rated motor current (parameter 107).
Warning against improper start
1. The motor can be stopped using di­gital commands, bus commands, references or local stop, while the frequency converter is connected to the mains. If personal safety requires elimination of any possibility of unin­tended start, these stops will not be
sufficient.
2. The motor can start during parameter
operation. Therefore always activate the ”Stop/Reset” key, after which
data can be changed.
3.
A stopped motor can start if a fault occurs in the frequency converter’s electronics or after a temporary overload, mains fault or faulty motor connection.
CAUTION: It is the responsibility of the user or person installing the drive to provide proper grounding and branch circuit protection for incoming power and motor overload according to National Electrical Codes (NEC) and local codes.
For the North American market
The Electronic Thermal Relay (ETR) in UL listed VLT®'s provides class 20 motor overload protection in accordence with NEC in single motor applications, when parameter 315 is set for "TRIP" and parameter 107 is set for nominal motor rated (nameplate) current. Effective from software version 1.10.

A frequency converter rectifies the a.c. voltage to D.C. voltage and then converts this D.C. voltage to A.C. voltage with variable amplitude and frequency.
The variable voltage and frequency supplying the motor make possible infinite speed control of standard three-phase asynchronous motors.

Introduction
9MG.30.A7.02 - VLT® is a registered Danfoss trademark
The features are obtained through a special switching pattern: the switching intervals are very short, which means high switching frequency, and the six semi­conductors of the inverter section are alternately held inactive, in pairs, through­out a 60° sine period. The current wave form of the motor current closely resembles that obtained on mains operation. The switching pause in 60° of the sine period also means that full-rated motor voltage can be obtained – and inverter switching losses are reduced by about one third.
The figures below show the switching pattern and the maximum motor voltage in relation to the mains voltage according to the VVC principle and the traditional PWM principle, respectively.
The full-rated motor voltage and the perfect current wave form mean that the Danfoss VLT
®
3000 Series allows full mo­tor performance without any derating – just like running the motor on the mains.
Technology
VLT® 3000 Series frequency converters
use an inverter control system known as the Voltage Vector Control (VVC)
developed by Danfoss. The VVC principle is superior to the traditional PWM (
Pulse Width Modulation) principle used in most modern frequency converters in the following ways:
Full-rated motor voltage at rated motor
frequency
Near perfect resemblance to the
sinusoidal mains supply
Extremely low switching losses, resulting
in high converter efficiency

The VLT® 3000 Series is delivered with a number of standard components which you would normally have to buy separately such as motor coils, mains reactor DC link coil and galvanic insulation (PELV).
These components built-in as standard give you the following advantages:
Save space and reduce costs
Simplify the installation as the
VLT
®
3000 will meet most demands.
Factory programmed U/f characteristics
Technology
Depending on the type of load, the
VLT® 3000 Series has dynamic adapting or
factory programmed U/f characteristics (motor voltage/frequency) giving the correct magnetisation of the motor, thus ensuring optimum dynamic, accuracy or efficiency.
It is possible to choose between 3 U/f characteristics for VT operation, offering the choice of optimising the start torque or reducing the noise level or power losses from the motor. A new parameter (106)
called “Automatic motor tuning” optimizes the motor parameters at constant load torque.

It is easy for the user to program the required functions on the keyboard of the
VLT® 3000 Series or via the terminals or
the RS 485 interface.
The digital technique used in the VLT
®
3000 Series makes it possible to program the different control inputs and signal outputs, and to select 4 different user­defined setups.
Programmable control inputs and signal outputs in 4 setups
Protected against mains disturbance
The VLT® 3000 Series is protected against transients arising on the mains, e.g. when you switch in power factor phase correction capacitors or when the supply is subject to lightning strikes.
Rated motor voltage and full torque can be maintained down to 10% undervoltage on the supply mains.
Low disturbance on the mains
As the VLT
®
3000 Series has coils in the intermediate circuit built-in as standard the harmonic generation is low.
This gives a good power factor, thus reducing the harmonic load on the mains supply.
Effective radio frequency interference suppression (EMC)
Technology
As standard the VLT® 3000 Series is delivered with built-in motor coils. This means that it is possible to install a long
Current measurement in all three motor phases gives perfect protection of the VLT
®
3000 series in the event of short circuits or earth faults on the motor terminals.
The continuous monitoring of the three motor phases makes switching on the motor cables possible e.g. by opening/ closing a contactor.
Long motor cables
Advanced VLT® protection
cable between motor and frequency converter without any additional coils.
Galvanic isolation
With the VLT® 3000 Series safety isolation is standard, as the high-voltage parts of the power section are galvanically isolated from the low-voltage parts of the control section in accordance with VDE 0160/0106 (PELV).
Advanced motor protection
The VLT® 3000 Series has a built-in electro­nic thermal motor protection. The frequency converter calculates the motor temperature on the basis of voltage, current, frequency and time. Therefore it is superior to the traditional bi-metallic protection where the altered cooling conditions due to the speed control are not taken into consideration.
The thermal motor protection is compar­able with thermal relay in the motor cables.
To achieve optimum protection against overheating of the motor when covered or blocked, or in case the ventilation should fail, it is possible to build in a thermistor and connect this to the frequency con­verter thermistor input (terminal 16, see page 102).
The effective monitoring of the three supply phases means that the VLT
®
3000 Series stops in the event of a missing phase. In this way overloading of the inverter and the capacitors of the intermediate circuit, which would reduce the lifetime of the frequency converter drastically, can be avoided.
The VLT
®
3000 Series has built-in thermal
protection of the unit as standard. The function turns off the inverter on thermal
overload.
The VLT
®
3000 Series can be delivered with an RFI filter complying with EN 55011. Filters are available as options or modules.
Some VLT
®
types have a mains filter as
standard in compliance with grade 1, class A.
12 MG.30.A7.02 - VLT® is a registered Danfoss trademark
Choice of frequency converter size
The frequency converter must be chosen on the basis of the actual motor current I
M
at maximum load of the plant. The rated continuous output current I
VLT,N
must be equal to or higher than the required motor current.
Sizing
Example:
In a heating plant (quadratic load) the pump motor is a 7.5 kW, 3 x 380 V, which at max. load takes up 14 A. Choose a VLT
®
3008 which can supply
16 A (I
VLT,N
) continuously.
Mains: 3 x 200/220/230 V and 3 x 220/230/240 V (see technical data)
Which one to choose?
The
VLT
®
types larger than 3004 (3008 at 500 V) have a higher output when using quadratic load, referred to as VT load (variable torque). Some technical specifications might change from CT to VT mode (e.g. the max. motor cable length decreases).

Warning The VLT® 3000 Series must always be
attached to the wall or floor before further installation. This rule must be complied with, particularly with regard to the very heavy larger VLT
®
types, to avoid injury to
people and equipment.
As an option for VLT® 3100-3150 a base for floor installation can be supplied (code nr. 175L3047).
VLT
®
3200-3250 is only intended for floor installation, and the base is therefore supplied as part of the VLT®. The base must be attached to the floor using 4 bolts before installation of the VLT
®
. The front panel of the base is unscrewed so that the VLT
®
can be secured through the 4 top holes in the base. See also section on cooling.
Base VLT
®
3100-3250
VLT® 3060-3150 is supplied with a mount­ing console placed behind the VLT
®
. This console also serves as an air channel for the cooling ribs, and on operation the console must be mounted on the VLT
®
.
The console does not have to be disman­tled for installation, but it can be removed temporarily by loosening the connecting bolts from the inside of the VLT
®
.
Remember to attach the console again. Otherwise there is great danger of cut-out due to overheating.
The 4 drop-shaped holes in the mounting console make it possible to attach the fixing bolts to the wall or in the panel before suspension of the VLT
®
.
The fixing bolts will be accessible through the top and bottom of the console to facilitate tightening.
VLT
®
3060-3075 is only for wall
installation. VLT
®
3100-3150 is supplied for wall
installation as standard.
The VLT® 3000 Series can be installed with flanges side by side
VLT® 3060-3250
Mechanical installation
The VLT® 3000 Series is cooled by natural convection. Therefore air must be able to pass freely under and above the unit.
VLT
®
3002-3052
This series must be installed on a flat surface so that the air flow can follow the cooling ribs right from the bottom of the VLT
®
. The VLT® with fixing holes in the side flanges can be installed with flange against flange. The VLT
®
without side flanges has fixing holes in top and base (IP 20) and can be installed without side spacing. See also section on cooling.

With the VLT® 3000 Series, all types of 3-phase asynchronous standard motors can be used.
In general, small motors (220/380 V, / ) are star-connected. Large motors are delta-connected (380/660 V, / ).
Motor connection
The factory setting will give clockwise rotation when the output of the VLT
®
3000
Series is connected as follows:
Terminal 96 connected with U phase Terminal 97 connected with V phase Terminal 98 connected with W phase
The rotation direction can be changed by swapping the two motor cable phases.
With the VLT® 3000 Series controls, the rotation direction can also be changed using the “reverse” function.
VLT® 3000 Series can control several motors connected in parallel. If the motor speeds must be different, motors of different rated speeds must be applied. The motor speed can be changed simul­taneously and the ratio between the rated motor speeds is maintained in the whole range.
The total current consumed by the motors may not exceed the maximum rated output current I
VLT,N
of the VLT® 3000 Series.
If motor sizes deviate considerably, prob­lems may arise during start and at low speed. This is due to the fact that small motors have a relatively high ohmic resist­ance in the stator, and therefore they require more start voltage during start and at low speed.
In systems with parallel motor operation, the internal overcurrent protection cannot be used as motor protection for the indi­vidual motor, since the output current must be programmed for the total motor current. Additional motor protection should there­fore be used, e.g. thermistors in each motor (or individual thermal relay).

EMC installation
The purpose 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 quality or specifications of a product. Three EU directives relate to frequency converters:
The machine directive (89/392/EEC)
All machines with critical, moving parts are comprised by the machine directive which came into force on 1 January 1995. Since a frequency converter is largely electrical by function, it does not fall under the
machine directive. However, if a frequency converter is supplied for use in a machine, we provide information about the safety aspects relating to the frequency con­verter. We do that by means of a manufac­turer’s declaration.
The low-voltage directive (73/23/EEC)
Frequency converters must be CE-labelled in accordance with the low-voltage direc­tive, which will come into force on 1 January 1997.
This directive applies to all electrical equipment and appliances used in the voltage range of 50-1000 VAC and 75­1500 VDC.
The EMC directive (89/336/EEC)
EMC is short for electromagnetic compat­ibility. The presence of electromagnetic compatibility means that the mutual interference between different compo­nents/appliances is so small that the
functioning of the appliances is not af­fected. The EMC directive comes into force on 1 January 1996. The directive distinguishes between components, appliances, systems and installations.
The EU “Guidelines on the Application of Council Directive 89/336/EEC” outline four typical situations of using a frequency converter. For each of these situations, explanations are offered as to whether the situation in question is covered by the EMC directive and must be CE-labelled.
1. The frequency converter is sold direct to the end-user. This applies for exam­ple if the frequency converter is sold to a DIY-market. The end-user is not an expert. He installs the frequency converter himself, e.g. for controlling a hobby machine or a domestic appli­ance. This frequency converter must be CE-labelled in accordance with the EMC directive.
2. The frequency converter is intended for use in a complete product. It is sold e.g. to a professional machine builder who has the technical knowledge it takes to install the frequency converter correctly. The frequency converter need not be CE-labelled in accordance with the EMC directive. Instead, the frequency converter manufacturer must be provide detailed guidelines on how to carry out an EMC-correct installa­tion.
3. The frequency converter is intended for use in an installation built up on the site of use by a professional. This could be e.g. a complete installation for manu­facturing purposes or for the genera­tion of heat/ventilation. The installation is planned and made by a professional installation builder. The complete system is not to be CE-labelled in accordance with the EMC directive. The system must comply with the basic requirements contained in the directive. This is ensured by using components, appliances and systems which are CE­labelled in accordance with the EMC directive.
4. The frequency converter is sold as part of a complete system, such as an air­conditioning system. The complete system must be CE-labelled in accord­ance with the EMC directive.

frequency converter and CE-labelling
CE-labelling is a positive feature when used for it original purpose, i.e. to facilitate trade within the EU and EFTA.
However, CE-labelling may cover many different specifications. This means that it has to be checked what a given CE-label specifically covers.
The specifications covered can in fact be widely different. That is why the CE-label can give installers a false feeling of secu­rity when using a frequency converter as a component in a system or an appliance.
We CE-label our VLT frequency convert­ers in accordance with the low-voltage directive. This means that as long as the frequency converter is installed correctly, we guarantee that it complies with the low-voltage directive. We issue a declara­tion of conformity confirming that our CE­label complies with the low-voltage direc­tive.
The CE-label also applies to the EMC directive on the condition that the EMC­correct installation and filtering in­structions in the manual have been followed. On this basis a conformity declaration is issued in accordance with the EMC directive.
To help ensure that your installation is EMC-correct, the manual provides de­tailed instructions for installation. Further­more, we specify which norms that are complied with by our products.
We offer the filters that meet the specifica­tions and can gladly provide other types of assistance that can help you obtain the best possible EMC result.

EMC installation
In support of our claim that the VLT
®
frequency converter complies with the protection requirements for emission and immunity under EMC directive 89/336/ EEC, a Technical Construction File (TCF) has been prepared for each model. Such a file defines the EMC requirements and the measurements made in accordance with harmonised EMC standards in a Power Drive System (PDS) that consists of a VLT
®
frequency converter, a control cable and the controls (control box), motor cable and motor plus any options added. The Technical Construction File is pre­pared on this basis in cooperation with an authorised EMC laboratory (Competent Body).
In most cases the VLT 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 EMC properties of the appliance, system or installation rests with the fitter. As an aid to the fitter, Danfoss has pre­pared EMC installation guidelines for the Power Drive System. The standards and testing levels stated for the Power Drive System are complied with, provided that the EMC-correct installation guidelines are applied.
The following basic issues need to be considered when installing a frequency converter, so as to obtain electromagnetic compatibility (EMC).
Safety earthing:
Please note: The frequency converter has a high leakage current and must be earthed appropriately for safety reasons. Apply local safety regulations.
High-frequency earthing:
Keep the earth wire connections as short as possible.
Connect the different earth systems at the lowest possible conductor impedance. The lowest possible conductor impedance is obtained by keeping the conductor as short as possible and by using the great­est possible surface area. A flat conductor,
for example, has a lower HF impedance than a round conductor for the same conductor square value.
If more than one appliance is installed in cabinets, the cabinet rear plate, which must be made of metal, should be used as a common earth reference plate. The metal cabinets of the different appliances are mounted on the cabinet rear plate using the lowest possible HF impedance. This avoids having different HF voltages for the individual appliances and avoids the risk of radio interference currents running in connection cables that may be used between the appliances. In order to obtain a low HF impedance, use the fastening bolts of the appliances as HF connection to the rear plate. It is necessary to remove insulating paint or similar from the fastening points.
The control cable and the filtered mains cable should be installed separately from the motor and brake cables to prevent interference coupling. Normally, a distance of 20 cm will be sufficient, but it is recom­mended to keep the greatest possible distance wherever possible, especially where cables are installed in parallel over a substantial distance. (Seperation should increase in proportion).
With respect to sensitive signal cables, such as telephone cables and data cables, the greatest possible distance is recom­mended with a minimum of 1 m per 5 m of power cable (mains, motor and brake cable). It must be pointed out that the
necessary distance depends on the sensi­tivity of the installation and the signal cables, and that therefore no precise values can be stated.
If cable clamps are used, sensitive signal cables are not to be placed in the same cable clamps as the motor cable or brake cable.
If signal cables are to cross power cables, this should be done at an angle of 90 degrees.
Remember that all noisy in- or outgoing cables to/from a cabinet should be screened or filtered.
Cables
Earthing
Compliance with EMC directive 89/336/EEC
Screened cables
The screen must be a low HF-impedance screem. This is ensured by using a braided screen of cobber, aluminium or iron.
Screen armour intended for mechanical protection, for example, is not suitable for an EMC-correct installation.
54 MG.30.A7.02 - VLT® is a registered Danfoss trademark
Electrical interference from the cable network, cable-borne interference, 150 kHz-30 MHz, and airborne interference from the drive system, 30 MHz-1 GHz, is for frequencies under approx. 50 MHz produced in particular by the inverter, the motor cable and the motor system.
As the sketch below shows, capacitive currents in the motor cable together with high du/dt from the motor voltage will produce interference.
Use of screened motor cable increases the leakage current I, (see fig. below). This is because screened cables have higher capacitance to earth than unscreened cables. If the leakage current is not fil­tered, it will cause greater interference on the mains in the radio leakage range under approx. 5 MHz. Since the leakage current I
1
is carried back to units through the screen (I4), in principle this will give only a small electromagnetic field from the screened motor cable, according to the figure below.
EMC installation
Radio interference in general
The screen reduces the radiated inter­ference, but increases the low frequency interference on the mains. With a mains filter, the interference level on the mains will be reduced to around the same level for both screened and unscreened cables.
The motor cable screen must be con­nected to the VLT
®
’s enclosure as well as the motor enclosure. The best way to do this is to use screen clamps to avoid unr ravelled screen ends. These increase the screen impedance at higher frequencies, which reduces the screen effect and increases the interference current (I
4
).
When screened cable is used for PROFIBUS, control cable, signal interface and brake, the screen must be mounted on the enclosure at both ends. In certain situations, however, it will be necessary to break the screen to avoid current loops.
In cases where the screen must be placed on a mounting panel for the VLT
®
fre­quency converter, the mounting panel must be of metal because the screen currents must be led back to the unit. It is also important to ensure good electrical contact from the mounting screws through the mounting curve to the VLT
®
frequency
converter. With regard to installation, it is generally
less complicated to use unscreened cables than screened cables. To observe the EN55011-1A requirements to radiated interference (30MHz-1GHz) a motor filter
must be installed when using
unscreened
cables. In order the reduce the interference level
from the system overall (unit + installation) as far as possible, it is important to make motor and brake cables as short as possible.
Cables with a sensitive signal level may not be led together with motor and brake cables.
Radio interference higher than 50 MHz (airborne) will be particularly affected by the control electronics.

Instructions for installation
Filtering

This can best be done through the fastening bolts for the enclosure (see instructions for installation, pp. 57-59, item A). Since the aluminium enclosure of the appliances is anodised and thus electrically insulating, toothed (serrated) washers should be used to penetrate the anodisation - or the ano­dised surface has to be removed.

EMC installation
Motor cable
In order to comply with the EMC specifi­cations concerning emission and immu­nity, the motor cable must be screened unless otherwise stated for the mains filter in question. It is important to keep the motor cable as short as possible so as to reduce the interference level and the leakage currents to a minimum.
The motor cable screen should be con­nected to the metal cabinet of the fre­quency converter and to the metal casing of the motor. Screen connections should be made using as large a surface as possible. (See the instructions for installa­tion, pp. 57-59, item D). The motor cable
screen should basically not be broken and not be earthed in the process. If it be­comes necessary to break the screen to install a motor isolator or motor relays, the screen should be continued at the lowest possible HF impedance.
Using filters 175H7083 and 175H7084, the VLT
®
3002-3008 complies with EN55011­1A using an unscreened motor cable. In addition to reducing the mains interfer­ence, the filters also reduce the interfer­ence radiating from the unscreened motor cable. As far as the motor cable is con­cerned, only interference above 30MHz is reduced (see EN55011-1A).
Control cables
Control cables should be screened. The screen should be connected using a clamp to the VLT
®
frequency converter base (see the instructions for installation, pp. 57-59, item C). Normally, the screen should also be connected to the base of the controlling appliance (follow the instructions for use of the appliance in question).
In connection with very long control cables and analogue signals, 50 Hz ripple loops may occur in rare cases, depending on the installation. This is because of interference coupling from the mains supply cables. In this connection it can be necessary to break the screen or possible insert a 100 nF condenser between screen and base.
Cable for serial communication
The cable for serial communication should be screened.
The screen should be installed using a clamp on the VLT
®
frequency converter (see the instructions for installation, pp. 57­59, item B).
With regard to cable specifications and instructions for installation in general, reference is made to the PROFIBUS product manual.
trolling appliance. They can be avoided by making a tight fit with the cabinet base rear plate, thereby ensuring that any equalising currents will run via the base rear plates and their joints, not via the cable screens.
Efforts should be made to avoid possible equalising currents that may occur when the control cable screen is connected to the base (earthed) at both ends. Equalising currents occur because of voltage differ­ences between the VLT
®
frequency
converter base and the base of the con-
Equalising currents
Brake cables
If a brake module is used, the cable to the brake resistor must be screened. In the case of VLT 3002 - VLT 3008, connect the screen to the conductive rear plate, on which the VLT frequency converter has been mounted. If VLT 3011 - VLT 3052 are used, mount the screen by means of a
special union. In the case of VLT 3060 ­VLT 3250, where the brake module is a separate module in its own casing, it is possible to use special unions or to terminate the screen in the conventional way. All sizes of unit require the screen to be connected to the brake resistor casing.

The control panel for programming and local control and information is placed on the front of the frequency converter. The control panel consists of a keyboard and a display. The keyboard is used for two purposes: local operation and programming. The display is used for communication between the frequency converter and the operator. On the control panel you will see a red and a green LED.
When the green LED (On) lights up, there is voltage to the frequency converter.
The red LED (Alarm) is used for alarm indications. In an ALARM MODE the LED will flash.
Using an optional adaptor and cable, the control panel can be mounted in a cabinet cover. The maximum distance between the frequency converter and the remote box is 3 m. The enclosure of the adapter (front) is IP 54.

Group description
Note: The choice between the 12 different
display read-outs mentioned on page 60 is not an element of this group.
Load and motor Group 1..
Operation and display Group 0..
In this group you will find parameters concerning the display read-out, local operation and setup handling.
This group of parameters has been re­ser-ved for the adjustments necessary to adapt the VLT
®
frequency converter to the
application and motor.
The preprogrammed values in parameters 100-105 are suitable for normal application using standard asynchronous motors with constant torque load without parallel­coupled motors.
If quadratic torque load is applied, select one of the VT (variable torque) modes or VT modes with CT starting torque (high break­away torque).
Parallel-coupled motors: If parallel-coupled motors or any synchro­nous type of motor are used at the output from a VLT
®
frequency converter, constant torque is selected without start compensa­tion in parameter 100, and open-loop speed control is selected in parameter 101.
Auto-optimization:
An additional tuning might improve the torque yield or speed accuracy, if the motor data differ from the typical values assumed as default.
Items 1-4 in Quick setup must be carried out first. The adaptive tuning facility offers you an easy way to perform that tuning. Initiate the tuning by setting parameter 106 to "ON" and pressing
Start
.
The VLT® will perform a test measurement of vital motor data and automatically adjust the appropriate parameters (108-113).
For optimum adjustment automatic para­meter tuning on a cold motor is recom­mended.
Caution: the motor will start running without warning. Manual tuning is possible in parameters 109-113 for correction of default or auto­matically tuned values.
Closed loop If closed loop control is required the trans­mitter, tachometer or encoder should sup­ply one of the standard analogue signals (e.g. 0-10 V, 0-20 mA; 4-20 mA) or a pulse signal frequency of max. 100 Hz, 1 kHz or 10 kHz (programmable). The full-scale value is always 100%.
The transmitter signal should be selected to utilise the full scale range as far as possible, but with due allowance for over­shooting. The pulse signal has an over-shooting range of up to 200% for the 100 Hz and 1 kHz signals, and up to 130% for the 10 kHz signal. To optimise dynamics and accuracy an im­pulse frequency as close to 10 kHz as pos­sible should be selected (at max. motor speed). If this is not possible, the transmitter signal can be corrected by the feedback scaling factor (parameter 125).
The equivalent reference signal can either be fixed internally (digital reference) or sup­plied via standard analogue signals or the pulse signal (range 0-100%). It is not possi­ble to select the same type of signal (volt­age, current, pulses) for both the reference and the feedback.
At start the output frequency is determined by the frequency converter’s reference and the feed forward factor and the min/max frequency settings. The feed forward factor is used to set the steady state output fre­quency.
Feedback scaling is used if the transmitter cannot be optimally selected for the input signals’ scale range.
The PID regulator then adjusts the output frequency by comparing reference and feedback.
At stop the controller output (integrator) is set to 0 so that a restart follows the normal start situation.

1. Start the frequency converter.
2. Increase the value in parameter 121 (proportional amplification) until the feedback signal (FB) oscillates constantly. Reduce the value until the oscillation ceases. Reduce further (0.4-0.6 times).
3. Reduce the value in parameter 122 (integration time) until the feedback signal (FB) oscillates again. Increase the value until the oscillation ceases. Then increase further 1.15-1.5 times.

The brake control for the electromechani­cal brake features functions which among other things improve positioning.
The brake control features an optimized relay function with a short reaction time, to control the electromechanical brake. The brake must be active (without voltage) while the unit is running idle. Relay 01/04 can be programmed so that the motor brake is released automatically when the programmed motor frequency is exceeded. It is possible to set separate ramp-up (start) and ramp-down (stop), cut-out and cut-in frequencies.

Introduction
Brake control
The motor current monitoring features a function which automatically activates the brake when the motor current drops to or below the programmed minimum value.
It is possible to override motor current monitoring during start-up. How long it is to be inactive depends on the delay setting.
To achieve high dynamics, start compen­sation is deselected in parameter 100.
The parameters for brake control are described below:

Relay
Programming of ramp-up and ramp­down times
In parameter 405 (terminal 29 input), two different ramp times can be selected. For normal start/stop, either ramp 1 or 2 can be selected. Quick stop is always ramp 2.
WARNING: The parameters for the relay used for brake control must not be changed (para. 409 or 410) as this can cause the brake to be released and thus damage equipment or endanger human life.

Serial data interface Group 5..
The serial bus communicates using RS 485 (terminals 68 and 69). It is possible to read and set the parameters of the VLT
®
frequency converter, and to give it refer­ence and control commands. The serial port can be used by up to 31 VLT
®
frequency converters per master without us­ing a repeater. If 3 repeaters are used, up to 99 VLT
®
frequency converters can be
connec-ted to one master.
It is important to connect and terminate the serial bus with the correct impedance to avoid any reflections which may disturb the cable’s data transmission.
This adjustment can take place by setting the 03.1 and 03.2 switches in the “on” posi­tion (see p. 148) in the last VLT
®
frequency
converter connected to the serial BUS.
Communication takes place by means of a protocol specified by Danfoss. The data format consists of 10 bits: one start bit (logically 0), eight data bits, and one
stop bit (logically 1). There is no parity check. Set the baud rate (speed of trans­mission) in parameter 501 and the ad­dress of each unit in parameter 500.
Telegram format / protocol
The communication protocol for the VLT
®
3000 Series consists of a 22-byte telegram using ASCII characters. These characters make it possible to operate, set and read parameters, and to receive status feed­back from the VLT
®
frequency converter. Communication takes place in the following way: The master sends a telegram to a VLT
®
frequency converter. Then the master awaits a reply from that frequency con­verter before sending a new message. The reply to the master is a copy of the telegram sent by the master, now containing any updated data values and the status of the VLT
®
frequency converter.

Byte 1:
Start byte which in this case must be the character ”<” (ASCII: 60).
Bytes 2 and 3:
The two-digit address of the frequency converter with which communication is required. This address is also programmed in parameter 500. Sending to address 00 means broadcast to all units connected to the bus. None of the units will reply, but they will carry out the command.
Byte 4:
Control parameter telling the VLT
®
frequency converter what to do with the following data values.
U (update) means that the data value (bytes 13-19) must be read into the frequency converter’s parameter (bytes 9-13).
R (read) means that the master wants to read the data value of the parameter stated in bytes 9-12.
C (control) means that the frequency con­verter reads only the four command bytes (5-8) and returns with status. Parameter number and data value will be ignored.
I (read index) means that the frequency converter reads index and parameter, and returns with status. Parameter is stated in bytes 9-12 and index is stated in bytes 13-18. Parameters with indices are read-only parameters. Action will be taken on the con­trol word. Two-dimensional indices (x,y) (parameters 601 and 602) are separated by a comma, see byte 19.
Example:
Index = x, y Data value = 013,05
Byte 14-18 = 013 05 Byte 19 = 2
Group description
Bytes 5-8:
Control and status words are used to send commands to the frequency converter and to send status from frequency converter to master.
Bytes 9-12:
In these bytes the parameter number is set.
Bytes 13:
Used for the sign before data value in bytes 14-18. All characters other than "−" are taken as "+".
Bytes 14-18:
Here is placed the data value of the para­meter stated in bytes 9-12. The value must be a whole number. If a decimal point is needed it is stated in byte
19. Note: Some data values have square brack­ets with a number, e.g. [0]. Use this number instead of the "text" data value.
Bytes 19:
The position of the decimal point in the data value stated in bytes 14-18. The number states the number of characters after the decimal point. Byte 19 can then be 0, 1, 2, 3, 4 or 5. For example, the number 23.75 is stated: Byte no. 13 14 15 16 17 18 19 ASCII character + 2 3 7 5 0 3 If byte 19 = 9 in the response telegram see table page 80.
Bytes 20, 21:
Used for counter control from byte 2 up to and including 19. The decimal values of the
ASCII characters are added and reduced to the two “low” characters, e.g. Σ 235 [ ] reduced = 35. If no control is necessary can­cel the function with “?” (ASCII: 63) in the two bytes.
Byte 22:
Stop byte stating the end of the telegram. The character ”>” is used (ASCII: 62).

The function of bit 04 can be redefined to D.C. brake in parameter 514. Otherwise the function is as described above. Note: In parameter 504/505 it is selected how bit 04 is connected (gates) with the equivalent function on the digital inputs.
Bit 05, Hold/ramp possible: Ordinary ramp stop which uses the ramp time in parameter 215/216. Bit 05 = “0” means stop, bit 05 = ”1” means that the frequency converter can start if the other start conditions are fulfilled.
Bit 06, Ramp stop/start: Ordinary ramp stop which uses the ramp time in parameter 215/216. Bit 06 = “0” means stop, bit 06 = “1” means that the frequency converter can start if the other start conditions are fulfilled. Note: In para­meter 506 it is selected how bit 06 is con­nected (gates) with the equivalent function on the digital inputs.
Bit 07, No function/reset: Reset of trip. Bit 07 = “0” means no reset, bit 07 = “1” means reset of a trip. Note: In parameter 508 it is selected how bit 07 is connected (gates) with the equivalent function on the digital inputs.
Bit 08, JOG 1 OFF/ON: Activation of preprogrammed speed in parameter 511 (Bus JOG 1). JOG 1 is only possible when bit 04 = “0” and bit 00-03 = “1”.
Bit 09, JOG 2 OFF/ON: Activation of preprogrammed speed in parameter 512 (Bus JOG 2). JOG 2 is only possible when bit 04 = “0” and bit 00-03 = “1”. If both JOG 1 and JOG 2 are activated (bit 08 and 09 = “1”), JOG has highest prio­rity, i.e. the speed programmed in parame­ter 511 is used.
Bit 10, Data not valid/valid: Used to tell the VLT
®
frequency converter whether the control word must be used or ignored. Bit 10 = “0” means that the control word is ignored. Bit 10 = “1” means that the control word is used. This function is rel­evant because the control word is always contained in the telegram, no matter which telegram type is used (see byte 4 in ”tel­egram format”), i.e. it is possible to discon-
nect the control word if it is not to be used in connection with updating or reading of parameters. Bit 11, No function/slow down: Used to reduce the speed reference with the value in parameter 513. Bit 11 = “0” means no change of reference, bit 11 = “1” means that the reference is reduced. The function of bit 11 and 12 can be rede-fined to selection of digital reference in param­eter 515, according to the following table:

Digital reference/
parameter
Bit 14
Bit 13
1/205 0 0 2/206 0 1 3/207 1 0 4/208 1 1
Note: In parameter 510 it is selected how bit 11/12 is connected (gates) with the equivalent function on the digital inputs.
Bit 12, no function/catch up:
Used to increase a speed reference with the value in parameter 513. Bit 12 = ”0” gives no chance of reference, bit 12 = ”1” increases the reference. If both slow-down and catch-up are activated (bit 11 and 12 = ”1”), slow-down has highest priority, i.e. the speed reference is reduced. The function of bit 11 and 12 can be redifined to selection of digital reference, see description of bit 11 above.
Bit 13/14, selection of setup: Bit 13 and 14 are used to select between four menu setups according to the follow­ing table:
Setup Bit 14 Bit 13
100 201 310 411
The function is only possible when
multi
setup
is selected in parameter 001.
Note: In parameter 509 it is selected how bit 13/14 are connected (gates) with the equivalent function on the digital inputs.

Bit 00, Control not ready/ready: Bit 00 = “0” means that the control word’s bit 00, 01 or 02 = “0” (OFF1, OFF2 or OFF3), or the VLT
®
frequency converter has tripped. Bit 00 = “1” means that the VLT
®
frequency converter is ready to operate when it receives the necessary start signals.
Big 01, VLT® not ready/ready: Same significance as bit 00.

®
frequency converter has tripped. Bit 02 = “1” means that the control word’s bit 00, 01, 02 and 03 = “1”, and the VLT
®
fre-
quency converter has not tripped.
Bit 03, No fault/trip: Bit 03 = “0” means that the VLT® frequency converter is not in a fault status. Bit 03 = “1” means that the VLT
®
frequency con­verter has tripped and it requires a reset signal before it can run.
Bit 04, ON2/OFF2: Bit 04 = “0” means that the control word’s bit 01 = “1”. Bit 04 = “1” means that the control word’s bit 01 = “0”.

Bit 06, Start possible/not possible: Bit 06 is always “0” if “Start not possible” [11] has not been selected in parameter
309. When “Start not possible” [11] is se­lected in parameter 309, bit 06 will be “1” after reset of a trip, after activation of OFF2 or OFF3 and after connection of mains voltage. “Start not possible” is reset, the control word’s bit 00 being set at “0” and bit 01, 02 and 10 at “1”.
Bit 07, No warning/warning: Bit 07 = “0” means that there is no extra­ordinary situation. Bit 07 = “1” means that an abnormal status has arisen for the VLT
®
frequency converter. All warnings described on pp. 124-125 will set bit 07 at “1”.
Bit 08, Speed in ref./speed = ref.: Bit 08 = “0” means that the motor’s cur-rent speed is different from the set speed reference. This can e.g. be the case while the speed is ramped up/down on start/stop. Bit 08 = “1” means that the motor’s current speed is equal to the set speed reference.
Bit 09, Local control/bus control: Bit 09 = “0” means that the VLT® frequen­cy converter has stopped with the help of the stop key on the operating panel, or “local” or “local with external free-wheeling stop” has been selected in parameter 003. Bit 09 = “1” means that it is possible to control the VLT
®
frequency converter via
the serial port.
Bit 10, Out of range/frequency OK: Bit 10 = “0” means that the output frequen­cy is outside the limits set in parameter 210 (Warning: Low frequency) and parameter 211 (Warning: High frequency). Bit 10 = “1” means that the output frequency is within the aforementioned limits.

When switch 04 is closed, there is no galvanic separation between the signal cables (terminals 68 and 69) and earth,
which can give problems if a master without galvanic separation is used. Therefore the following connection method should be used: Switch 04 must be open, the signal cable’s screen must be con­nected to the relief stirrup below the control card, but not to terminal 61. The screen is uncovered and clamped under the relief stirrup, the screen may not end at the relief stirrup, but must be led as close to the terminal block as possible, so that the unscreened signal cable ends are as short as possible.

Parameter description 1.. Load and motor
Function:
Adjustment of the VLT® frequency convert­er’s U/f characteristics to the load torque’s characteristics.
Description of choices:
Variable torque (VT) low, medium or high is selected if the load is quadratic (centrifu­gal pumps, fans). Choice of torque should normally be made with due consideration of problem-free operation, lowest possible energy consumption and least possible acoustic noise.
Variable torque (VT) low, medium or high with constant torque (CT) start is selected if there is a need for higher break-away torque than can be achieved with the three aforementioned characteristics. The con­stant torque curve is followed until the set reference is reached, after which the vari­able torque characteristics are followed.
Constant torque without start compensa­tion is a load-independent U/f characteristic used for parallel-coupled motors and synchronous type motors.
Constant torque with start compensation is a load-dependent U/f characteristic where the output voltage is increased on increas­ing load (current) to maintain con-stant magnetization of the motor and to compen­sate for loss in the motor during start.
Constant torque with 4 quadratic slip compensation has the same function as described for [7] but with slip compensation for both motor and regenerative op­eration. Slip compensation on regenerative operation will usually require use of the brake option/module. However, the slip compensation is only active if the function is selected in parameter 101.

Value:
Open loop (open loop) [0] Slip compensated (slip comp) [1]
Closed loop (closed loop) [2]
Function:
It is possible to select three different types of speed control: open loop, slip compensation and closed loop.
Description of choices:
Open loop is selected when parallel-coup­led motors or synchronous type motors are used, or if slip compensation is not required for another reason. Slip compensation is selected on normal operation where constant motor speed is required, with varying load. Closed loop is selected if operation with process feedback is required. This selection also requires selection of feedback type in parameter 114 (current, voltage or pulsa­tions) and setting of PID regulator para­meters (119-125).

Function:
The current limit can be set in parameter 209 and in parameter 412 or 413 with the help of a current or voltage signal.
Description of choices:
Preprogrammed value is selected when a fixed set limit for current is required. This current limit is set in parameter 209. Voltage signal is selected if the current limit is to be changed during operation with the help of a control signal of e.g. 0-10 V on analogue input 53 (parameter 412) where 0 V will correspond to 0% current and 10 V to the value in parameter 209. Current signal is selected on e.g. 0-20 mA on analogue input 60 (parameter 413). Here 0 mA will correspond to 0% current limit and 20 mA will correspond to the value in parameter 209.
Note: The start conditions (terminals 18 and
27) must be present together with a speed reference (possibly digital ref. parameter 205-208) so that current limit control can be used.
Warning:
If the aforementioned conditions exist when the unit is switched on, the motor can rotate for up to 5 sec. even though the current limit setting is 0.

Function: Selection of connected motor size in kW. This data value is e.g. used for automatic setting of other motor parameters 107-113.
Description of choices:
Read rated motor output in kW from the motor’s type plate and select this value. If this value deviates significantly from the setting options, select the closest low or high value (under- or oversize). The para­meters 107-113 must then be optimized manually with standard settings for motors from 0.55-200 kW.

Select the rated motor output (V) on the motor plate. Parameters 107-113 are changed auto­matically. All values can be addressed via the bus. It is possible to select 440 V motor voltage on a 400 V unit. This can be used to optimise motor voltage on using e.g. a 440 V motor on 415 V mains voltage. If the VLT
®
types 3060-3250 is factory set to 500 V, so that the lowest motor voltage which can be selected is 440 V, this can be adjusted in parameter 650 by changing the data values to the same VLT

106 Automatic motor adaption
(Auto motor set)
Value:
From (Tuning-off) [0] To (Tuning-on) [1]
If this parameter is set to
”on”
, the fre­quency converter automatically sets the compensation parameters 108-113. Auto­matic motor adaption is started by pressing if the unit is in local setting. If the unit is set to remote control, an external start signal is given (terminals 18 and 27). After auto­matic motor adaption, the values switches automatically to
”from”
and the unit trips. After automatic motor adaption the unit goes into alarm mode, trips and displays “AUTOTUN.OK” or “AUTOTUN.FAULT”. The unit can be reset by pressing
Stop
Reset
or by activating the reset input (parameter 400, terminal 16 or parameter 401, terminal 17). Automatic motor adaption is possible with up to 50% load on the shaft. Automatic motor adaption is possible only on motor sizes which can be selected in pa­rameter 103 and after setting parameters 103-105.
Warning: The motor will run at 20 Hz dur­ing part of the tuning. The direction is de-
termined by the reversing signal to terminal 19 (parameter 403), serial bus (parameter 507), local rotation direction (parameter 008) and the sign of the refer­ence signal.

300 Brake option
(Brake option)
Value:
Not applied (not applied) [0] Applied (applied) [1]
The parameter is used with the brake op­tion and brake resistor. A higher interme-
diate circuit voltage during braking is permitted.
Parameter description 3.. Functions and timers
301 Start frequency
(Start freq.)
Value:
0.0 - 10 Hz 0.0
Insert the start frequency at which the motor is to start (can e.g. be used on raise/ lower application).
Value:
0.0 - 1 sec. 0.0
302 Start delay
(Start delay)
The VLT® frequency converter will start on the start frequency (parameter 301) and start ramping up after the start delay time is over.
Set the time needed for high starting torque. A high initial torque means that a current of 2 x the current limit in parameter 209 is permitted. However, the current is limited by the inverter’s protection limit.
Value:
0.0 - 1 sec. 0.0
303 High starting torque
(HI start torq)
Function:
Select one of the 3 ramp-down functions to prolong the ride through time at mains fail­ure. The effect will depend on the load and the mains voltage before failure.
Description of choices:
UNCONTROLLED STOP: The motor will continue running at the selected speed un­til control trips. RAMP-DOWN 1: The motor will start to ramp down imme-diately (parameter 216) until control trips. RAMP-DOWN 2: The motor will start to ramp down immediately (parameter 218). Reliable regenerative operation of the frequency converter over the ramp down 1 or 2 function requires a large inertia force and negligible operational motor load on the frequency converter.
Value:
Uncontrolled stop (stop) [0] Ramp-down 1 (ramp stop) [1] Ramp-down 2 (alt. ramp st.) [2]
304 Mains failure
(Power fail)
Function:
The parameter is used when the VLT
®
frequency converter is cut in on a rotating motor (e.g. after current has been disconnected). This function is optimal at a
4.5 kHz switching frequency. The function may not work properly when using another switching frequency.
Description of choices:
OK - same direction: Chosen if the motor can only rotate in same direction on cut-in. OK - both directions: Chosen when the motor can only rotate in both directions on cut-in. Stop - before start: Selected if the motor is to be stopped using d.c brake before the motor is ramped up to the desired speed. The D.C. brake time must be set in parameter 306. The selected function is activated in accordance with the diagram on p. 72.
Value:
Disable (disable) [0] OK - same direction (same direct) [1] OK - both directions (both direct) [2] DC-brake before start

Depending on unit
If the stator in an asynchronous motor is supplied with D.C. voltage, a braking torque will arise. Select the duration of the impressed D.C. current injection (306). Pay attention to the motor’s power set-off. Thermal motor protection is also updated at DC braking.
Select at what output frequency the D.C. brake is to be activated on ramp-down to stop (para. 307). Parameters 306 and 307 must be other than 0 to activate the D.C. brake. The D.C. brake can also be acti­vated via terminal 27 (parameter 404).
The brake torque depends on the selected D.C. brake voltage (para. 308).
Warning:
An excessive value can damage the motor due to overheating.
A start signal must be present after power­up to provide DC-braking by means of a stop signal.
Software version 3.11 Value:
0.0 - 50.0 V 0.0
If the frequency converter is to reset automatically, select automatic reset 1-10.
Warning: The motor can start without
warning. Select how many times the frequency converter is to reset auto­matically after cut-out within 20 min.
Start disabled blocks re-start after trip­ping. Start disabled functions only in connection with serial communication, since re-start is only possible via the bus. If start disabled is used
without
simultane­ous use of the bus, re-start is disabled. Start disabled provides for application of the status table as in PROFIBUS when the control word is ON1, ON2 and ON3. The status table can be found in PROFI­BUS literature, MG.10.AX.02.

309 Reset mode
(Reset mode)
Value:
0 - 60 sec. ✭ OFF
When the frequency converter registers that the output current has exceeded the current limit I
LIM
(parameter 209) it will await a trip. Record for how long you want the frequency converter to wait before tripping out. OFF signifies that the time is infinite.

311 Trip delay at inverter fault
(Trip dly@fault)
Value:
0 - 35 sec.
Software version 3.11:
Under voltage fixed 25 sec. Over voltage 0 sec.
When the frequency converter registers an over- or under-voltage in the inverter it will await a final trip. Record for how long you want the frequency converter to wait beforetripping out.
Note: If this value is reduced from the factory setting, the unit may report a fault at Power on (undervoltage).

Sets the max. time allowed for auto restart before a final trip, if selected in para. 309.
314 Motor pre-heat
(Motor pre-heat)
Value:
Off (OFF) [0] On (ON) [1]
If
"on"
is selected the motor will be pre­heated by a DC current when motor coasting is permitted (terminal 27 = on) and no start command has been given (START, START REV. or JOG). This func­tion is not found for VLT
®
types 3032-3052,
230 V, and VLT

The frequency converter calculates whether the motor temperature exceeds the permissible limits. The calculation is based on 1.16 x rated motor current (set in parameter 107). Four separate calcula­tions are possible, so that one can be chosen for each setup or the same calculation can be used in several setups. Select
off
if you do not want either warning or trip. Select
warning only
if you want a warning in the display when the motor is overheating. You can also program the frequency con­verter to give a warning signal via the signal outputs (parameters 407-410).
Select “trip”
if trip is required when the motor is overloaded. You can also program the frequency con­verter to give a alarm signal via the signal outputs (parameters 407-410). See graph on page 130.
