2 Safety and Conformity

2.1 Safety PrecautionsEquipment containing electrical componentsmay not be disposed of together with domesticwaste.It must be separately collected with electricaland electronic waste according to local andcurrently valid legislation.

MCC 101/102Design Guide

2.1.1 CE Conformity and Labelling

What is CE Conformity and Labelling?The purpose of CE labelling is to avoid technical tradeobstacles within EFTA and the EU. The EU has introduced theCE label as a simple way of showing whether a productcomplies with the relevant EU directives. The CE label saysnothing about the specifications or quality of the product.The low-voltage directive (73/23/EEC)Frequency converters must be CE labelled in accordancewith the low-voltage directive of January 1, 1997. Thedirective applies to all electrical equipment and appliancesused in the 50 - 1000V AC and the 75 - 1500V DC voltageranges. Danfoss CE-labels in accordance with the directiveand issues a declaration of conformity upon request.

Warnings

CAUTIONWhen in use the filter surface temperature rises. DO NOTtouch the filter during operation.

WARNINGNever work on a filter in operation. Touching the electricalparts may be fatal - even after the equipment has beendisconnected from the frequency converter or motor.

WARNINGBefore servicing the filter, wait at least the voltage dischargetime stated in the Design Guide for the correspondingfrequency converter to avoid electrical shock hazard.

NOTENever attempt to repair a defect filter.

NOTEThe filters presented in this design guide are speciallydesigned and tested for Danfoss frequency converters (FC102/202/301 and 302). Danfoss takes no resposibility for theuse of third party output filters.

NOTEThe phased out LC-filters that were developed for theVLT5000 series and are not compatible with the VLT FC100/200/300.However, the new filters are compatible with both FC-seriesand VLT 5000-series

NOTE690V applications:For motors not specially designed for frequency converteroperation or without double insulation, Danfoss highlyrecommend the use of either dU/dt or Sine-Wave filters.

NOTESine-wave filters can be used at switching frequencies higherthan the nominal switching frequency, but should never beused at switching frequencies with less than 20% lower thanthe nominal switching frequency.

NOTEdU/dt filters, unlike Sine-wave filters, can be used at lowerswitching frequency than the nominal switching frequency,but higher switching frequency will cause overheating of thefilter and should be avoided.

3 Introduction to Output Filters

3.1 Why use Output Filters

This chapter describes why and when to use Output Filterswith Danfoss frequency converters. It is divided into 4sections:

• Protection of Motor Insulation• Reduction of Motor Acoustic Noise• Reduction of High Frequency Electromagnetic

Noise in Motor Cable

• Bearing currents and shaft voltage

3.2 Protection of Motor Insulation

3.2.1 The Output Voltage

The output voltage of the frequency converter is a series oftrapezoidal pulses with a variable width (pulse widthmodulation) characterized by a pulse rise-time tr.

When a transistor in the inverter switches, the voltage acrossthe motor terminal increases by a dU/dt ratio that dependson:

• the motor cable (type, cross-section, length,screened or unscreened, inductance andcapacitance)

• the high frequency surge impendance of the motorBecause of the impedance mismatch between the cablecharacteristic impedance and the motor surge impedance awave reflection occurs, causing a ringing voltage overshootat the motor terminals - see Illustration 3.1. The motor surgeimpedance decreases with the increase of motor sizeresulting in reduced mismatch with the cable impedance.The lower reflection coefficient (Γ) reduces the wavereflection and thereby the voltage overshoot. Typical valuesare given in Table 3.1.In the case of parallel cables the cable characteristicimpedance is reduced, resulting in a higher reflectioncoefficient higher overshoot. For more information pleasesee IEC 61800-8.

Typical values for the rise time and peak voltage UPEAK aremeasured on the motor terminals between two phases.

Two different definitions for the risetime tr are used inpractice. The international IEC standards define the rise-timeas the time between 10% to 90% of the peak voltage Upeak.The US National Electrical Manufacturers Association (NEMA)defines the rise-time as the time between 10% and 90% ofthe final, settled voltage, that is equal to the DC link voltageUDC. See Illustration 3.2 and Illustration 3.3.

To obtain approximate values for cable lengths and voltagesnot mentioned below, use the following rules of thumb:

1. Rise time increases with cable length.

2. UPEAK = DC link voltage x (1+Γ); Γ represents thereflection coefficient and typical values can befound in table below(DC link voltage = Mains voltage x 1.35).

3. dU/dt = 0.8 × UPEAK

tr (IEC)

dU/dt = 0.8 × UDCtr(NEMA )

(NEMA)

(For dU/dt, rise time, Upeak values at different cable lengthsplease consult the drive Design Guide)

3.3 Reduction of Motor Acoustic Noise

The acoustic noise generated by motors has three mainsources.

1. The magnetic noise produced by the motor core,through magnetostriction

2. The noise produced by the motor bearings

3. The noise produced by the motor ventilation

When a motor is fed by a frequency converter, thepulsewidth modulated (PWM) voltage applied to the motorcauses additional magnetic noise at the switching frequencyand harmonics of the switching frequency (mainly thedouble of the switching frequency). In some applications thisis not acceptable. In order to eliminate this additionalswitching noise, a sine-wave filter should be used. This willfilter the pulse shaped voltage from the frequency converterand provide a sinusoidal phase-to-phase voltage at themotor terminals.



3 3

3.4 Reduction of High Frequency Electromagnetic Noise in the Motor Cable

When no filters are used, the ringing voltage overshoot that occurs at the motor terminals is the main high-frequency noisesource. Illustration 3.5 shows the correlation between the frequency of the voltage ringing at the motor terminals and thespectrum of the high-frequency conducted interference in the motor cable.Besides this noise component, there are also other noise components such as:

• The common-mode voltage between phases and ground at the switching frequency and its harmonics - highamplitude but low frequency.

• High-frequency noise (above 10MHz) caused by the switching of semiconductors - high frequency but low amplitude.

Illustration 3.5 Correlation Between the Frequency of the Ringing Voltage Overshoot and the Spectrum of Noise Emissions.

When an output filter is installed following effect is achieved:

• In the case of dU/dt filters the frequency of the ringing oscillation is reduced below 150kHz.• In the case of sine-wave filters the ringing oscillation is completely eliminated and the motor is fed by a sinusoidal

phase-to-phase voltage.

Remember, that the other two noise components are still present. This is illustrated in the conducted emission measurementsshown in Illustration 3.7 and Illustration 3.8. The use of unshielded motor cables is possible, but the layout of the installationshould prevent noise coupling between the unshielded motor cable and the mains line or other sensitive cables (sensors,communication, etc.). This can be achieved by cable segregation and placement of the motor cable in a separate, continuousand grounded cable tray.

3.5 What are Bearing Currents and ShaftVoltages?

Fast switching transistors in the frequency convertercombined with an inherent common-mode voltage (voltagebetween phases and ground) generate high-frequencybearing currents and shaft voltages. While bearing currentsand shaft voltages can also occur in direct-on-line motors,these phenomena are accentuated when the motor is fedfrom a frequency converter. The majority of bearingdamages in motors fed by frequency converters are becauseof vibrations, misalignment, excessive axial or radial loading,improper lubrication, impurities in the grease. In some cases,bearing damages are caused by bearing currents and shaftvoltages. The mechanism that causes bearing currents andshaft voltages is quite intricate and beyond the scope of thisDesign Guide. Basically, two main mechanisms can beidentified:

• Capacitive coupling: the voltage across the bearingis generated by parasitic capacitances in the motor.

• Inductive coupling: caused by circulating currentsin the motor.

The grease film of a running bearing behaves like isolation.The voltage across the bearing can cause a breakdown of thegrease film and produce a small electric discharge (a spark)between the bearing balls and the running track. Thisdischarge produces a microscopic melting of the bearing balland running track metal and in time it causes the prematurewear-out of the bearing. This mechanism is called ElectricalDischarge Machining or EDM.

3.5.1 Mitigation of Premature Bearing Wear-Out

There are a number of measures that can be taken forpreventing premature wearing and damage of the bearings(not all of them are applicable in all cases – combinationscan be used). These measures aim either to provide a low-impedance return path to the high-frequency currents or toelectrically isolate the motor shaft for preventing currentsthrough the bearings. Besides, there are also mechanicalrelated measures.

Measures to provide a low-impedance return path

• Follow EMC installation rules strictly. A good high-frequency return path should be provided betweenmotor and frequency converter, for example byusing shielded cables.

• Make sure that the motor is properly grounded andthe grounding has a low-impedance for high-frequency currents.

• Provide a good high-frequency ground connectionbetween motor chassis and load.

• Use shaft grounding brushes.

Measures that isolate the motor shaft from the load

• Use isolated bearings (or at least one isolatedbearing at the non-driving end NDE).

• Prevent shaft ground current by using isolatedcouplings.

Mechanical measures

• Make sure that the motor and load are properlyaligned.

• Make sure the loading of the bearing (axial andradial) is within the specifications.

• Check the vibration level in the bearing.• Check the grease in the bearing and make sure the

bearing is correctly lubricated for the givenoperating conditions.

One of the mitigation measures is to use filters. This can beused in combination with other measures, such as thosepresented above. High-frequency common-mode (HF-CM)filters (core kits) are specially designed for reducing bearingstress. Sine-wave filters also have a good effect. dU/dt filtershave less effect and it is recommended to use them incombination with HF-CM cores.

3.5.2 Measuring Electric Discharges in theMotor Bearings

The occurrence of electric discharges in the motor bearingscan be measured using an oscilloscope and a brush to pickup the shaft voltage. This method is difficult and theinterpretation of the measured waveforms requires a deepunderstanding of the bearing current phenomena. An easyalternative is to use an electrical discharge detector(130B8000), as shown in Illustration 3.6. Such a deviceconsists of a loop antenna that receives signals in thefrequency range of 50MHz – 200MHz and a counter. Eachelectric discharge produces an electromagnetic wave that isdetected by the instrument and the counter is incremented.If the counter displays a high number of discharges it meansthat there are many discharges occurring in the bearing andmitigation measures have to be taken to prevent the earlywear out of the bearing. This instrument can be used forexperimentally determining the exact number of coresneeded to reduce bearing currents. Start with a set of 2cores. If the discharges are not eliminated, or drasticallyreduced, add more cores. The number of cores presented inthe table above is a guiding value that should cover mostapplications with a generous safety margin. If the cores areinstalled on the drive terminals and you experiment coresaturation because of long motor cables (the cores have noeffect on bearing currents), check the correctness of theinstallation. If cores keep saturating after the installation ismade according to EMC best practice, consider moving thecores to the motor terminals.

Table 3.2 Comparison of dU/dt and Sine-wave Filters

1) Not 690V.2) See general specification for formula.

3.6.1 dU/dt Filters

The dU/dt filters consist of inductors and capacitors in a lowpass filter arrangement and their cut off frequency is abovethe nominal switching frequency of the frequency converter.The inductance (L) and capacitance (C) values are shown inthe tables in 4.2 Electrical Data - dU/dt Filters. Compared toSine-wave filters they have lower L and C values, thus theyare cheaper and smaller. With a dU/dt filter the voltage waveform is still pulse shaped but the current is sinusoidal - seefollowing illustrations.

Features and benefitsdU/dt filters reduce the voltage peaks and dU/dt of thepulses at the motor terminals. The dU/dt filters reduce dU/dtto approx. 500V/μs.

Advantages

• Protects the motor against high dU/dt values andvoltage peaks, hence prolongs the lifetime of themotor

• Allows the use of motors which are not specificallydesigned for converter operation, for example inretrofit applications

Application areasDanfoss recommends the use of dU/dt filters in the followingapplications:

• Applications with frequent regenerative braking• Motors that are not rated for frequency converter

operation and not complying with IEC 600034-25

• Motors placed in aggressive environments orrunning at high temperatures

• Applications with risk of flash over



33

• Installations using old motors (retrofit) or generalpurpose motors not complying with IEC 600034-17

• Applications with short motor cables (less than15m)

• 690V applications

Illustration 3.11 Measured dU/dt values (rise time and peakvoltages) with and without dU/dt filter using 15m, 50m and 150mcable lengths on a 400V, 37kW induction motor.

The dU/dt value decreases with the motor cable lengthwhereas the peak voltage increases (see Illustration 3.11). TheUpeak value depends on the Udc from the frequency converterand as Udc increases during motor braking (generative) Upeakcan increase to values above the limits of IEC 60034-17 andthereby stress the motor insulation. Danfoss thereforerecommends dU/dt filters in applications with frequentbraking. Furthermore the illustration above shows how theUpeak increases with the cable length. As the cable lengthincreases, the cable capacitance rises and the cable behaveslike a low-pass filter. That means longer rise-time tr for longercables. Therefore it is recommended to use dU/dt filters onlyin applications with cable lengths up to 150m. Above 150mdU/dt filters have no effect. If further reduction is needed,use a sine-wave filter.

• Filters wall mounted up to 177A and floor mountedabove that size

Illustration 3.13 690V - With and Without dU/dt Filter

Source: Test of 690V 30kW VLT FC 302 with MCC 102 dU/dtfilter

Illustration 3.12 and Illustration 3.13 show how Upeak and risetime behaves as a function of the motor cable length. Ininstallations with short motor cables (below 5-10m) the risetime is short which causes high dU/dt values. The high dU/dtcan cause a damaging high potential difference between thewindings in the motor which can lead to breakdown of theinsulation and flash-over. Danfoss therefore recommendsdU/dt filters in applications with motor cable lengths shorterthan 15m.

3.6.2 Sine-wave Filters

Sine-wave filters are designed to let only low frequenciespass. High frequencies are consequently shunted awaywhich results in a sinusoidal phase to phase voltagewaveform and sinusoidal current waveforms. With thesinusoidal waveforms the use of special frequency convertermotors with reinforced insulation is no longer needed. Theacoustic noise from the motor is also damped as aconsequence of the sinusoidal wave condition. The sine-wave filter also reduces insulation stress and bearingcurrents in the motor, thus leading to prolonged motorlifetime and longer periods between services. Sine-wavefilters enable use of longer motor cables in applicationswhere the motor is installed far from the frequencyconverter. As the filter does not act between motor phasesand ground, it does not reduce leakage currents in thecables. Therefore the motor cable length is limited - seeTable 3.2.

The Danfoss Sine-wave filters are designed to operate withthe VLT® FC 100/200/300. They replace the LC-filter productrange and are backwards compatible with the VLT5000-8000 Series Drives. They consist of inductors andcapacitors in a low-pass filter arrangement. The inductance(L) and capacitance (C) values are shown in tables in4.3 Electrical Data - Sine-wave Filters.

Features and benefitsAs described above, Sine-wave filters reduce motorinsulation stress and eliminate switching acoustic noise fromthe motor. The motor losses are reduced because the motoris fed with a sinusoidal voltage, as shown in Illustration 3.12.Moreover, the filter eliminates the pulse reflections in themotor cable thus reducing the losses in the frequencyconverter.

Advantages

• Protects the motor against voltage peaks henceprolongs the lifetime

• Reduces the losses in the motor• Eliminates acoustic switching noise from the motor• Reduces semiconductor losses in the drive with

long motor cables

• Decreases electromagnetic emissions from motorcables by eliminating high frequency ringing in thecable

• Reduces electromagnetic interference fromunscreened motor cables

• Reduces the bearing current thus prolonging thelifetime of the motor

• Applications where the acoustic switching noisefrom the motor has to be eliminated

• Retrofit installations with old motors with poorinsulation

• Applications with frequent regenerative brakingand motors that do not comply with IEC 60034-17

• Applications where the motor is placed inaggressive environments or running at hightemperatures

• Applications with motor cables above 150m up to300m (with both screened and unscreened cable).The use of motor cables longer than 300mdepends on the specific application

• Applications where the service interval on themotor has to be increased

• 690V applications with general purpose motors• Step up applications or other applications where

the frequency converter feeds a transformer

• Parallel filter installation is possible withapplications in the high power range

3.6.3 High-Frequency Common-Mode CoreKits

High-frequency common-mode (HF-CM) core kits are one ofthe mitigation measures to reduce bearing wear. However,they should not be used as the sole mitigation measure.Even when HF-CM cores are used, the EMC-correct instal-lation rules must be followed. The HF-CM cores work byreducing the high-frequency common-mode currents thatare associated with the electric discharges in the bearing.They also reduce the high-frequency emissions from themotor cable which can be used, for example, in applicationswith unshielded motor cables.

Table 4.2 Filter Selection

Generally the output filters are designed for the nominalswitching frequency of the frequency converter.

NOTESine-wave filters can be used at switching frequencies higherthan the nominal switching frequency, but should never beused at switching frequencies with less than 20% lower thanthe nominal switching frequency.

NOTEdU/dt filters, unlike Sine-wave filters, can be used at lowerswitching frequency than the nominal switching frequency,but higher switching frequency will cause the overheating ofthe filter and should be avoided.

4.1.2 HF-CM Selection

The cores can be installed at the frequency converter’soutput terminals (U, V, W) or in the motor terminal box.

When installed at the frequency converter’s terminals theHF-CM kit reduces both bearing stress and high-frequencyelectromagnetic interference from the motor cable. Thenumber of cores depends on the motor cable length andfrequency converter voltage and a selection table is shownbelow.

When installed in the motor terminal box the HF-CM kitreduces only bearing stress and has no effect on the electro-magnetic interference from the motor cable. Two cores aresufficient in most cases, independent of the motor cablelength.

Danfoss provides the HF-CM cores in kits of two pieces/kit.The cores are oval shaped for the ease of installation and areavailable in four sizes: for A and B frames, for C frames, for Dframes, for E and F frames. For F frame frequency converters,one core kit shall be installed at each inverter moduleterminals. Mechanical mounting can be made with cable ties.There are no special requirements regarding mechanicalmounting.

In normal operation the temperature is below 70°C.However, if the cores are saturated they can get hot, withtemperatures above 70°C. Therefore it is important to usethe correct number of cores to avoid saturation. Saturationcan occur if the motor cable is too long, motor cables areparalleled or high capacitance motor cables, not suitable forfrequency converter operation, are used. Always avoid motorcables with sector-shaped cores. Use only cables with round-shaped cores.

CAUTIONCheck the core temperature during commissioning. Atemperature above 70°C indicates saturation of the cores. Ifthis happens add more cores. If the cores still saturate itmeans that the cable capacitance is too large because of: toolong cable, too many parallel cables, cable type with highcapacitance.

Applications with parallel cablesWhen parallel cables are used the total cable length has tobe considered. For example 2 x 100m cables are equivalentwith one 200m cable. If many paralleled motors are used aseparate core kit should be installed for each individualmotor.

The ordering numbers for the core kits (2 cores/package) aregiven in the following table.

5 How to Install

5.1 Mechanical Mounting

5.1.1 Safety Requirements for MechanicalInstallation

WARNINGPay attention to the requirements that apply to integrationand field mounting kit. Observe the information in the list toavoid serious damage or injury, especially when installinglarge units.

The filter is cooled by natural convection.To protect the unit from overheating it must be ensured thatthe ambient temperature does not exceed the maximumtemperature stated for the filter. Locate the maximumtemperature in the paragraph Derating for AmbientTemperature.If the ambient temperature is in the range of 45°C - 55°C,derating of the filter will become relevant.

5.1.2 Mounting

• All wall mounted filters must be mounted verticallywith the terminals at the bottom.

• Do not mount the filter close to other heatingelements or heat sensitive material (such as wood)

• The filter can be side-mounted with the frequencyconverter. There is no requirement for spacingbetween the filter and frequency converter.

• Top and bottom clearance is minimum 100mm(200mm for foot print filters).

• The surface temperature of IP20/23 units does notexceed 70°C.

• The surface temperature of IP00 filters can exceed70°C and a hot surface warning label is placed onthe filter.

5.1.3 Mechanical Installation of HF-CM

The HF-CM cores have an oval shape to allow easier instal-lation. They should be placed around the three motor phases(U, V and W). It is important to put all three motor phasesthrough the core, else the core will saturate. It is alsoimportant not to put the PE or any grounding wires throughthe core, else the core will loose its effect. In mostapplications several cores have to be stacked.

Illustration 5.1 Correct Installation

PE U V W

130B

B727

.10

Illustration 5.2 Wrong Installation. The PE should not go throughthe core.

The cores can vibrate due to the alternating magnetic field.When close to the cable’s isolation or other parts, it ispossible that the vibration causes the wearing of the core orcable isolation material. Use cable ties to secure the coresand cable.

5.1.4 Earthing of Sine-wave and dU/dt Filters

WARNINGThe filter must be earthed before switching the power on(high leakage currents).

Common mode interferences are kept small by ensuring thatthe current return path to the frequency converter has thelowest possible impedance.

• Choose the best earthing possibility (e.g. cabinetmounting panel)

• Use the enclosed (in accessory bag) protectiveearth terminal to ensure the best possible earthing

• Remove any paint present to ensure good electricalcontact

• Ensure that the filter and frequency converter makesolid electrical contact (high frequency earthing)

• The filter must be earthed before switching thepower on (high leakage currents)

5.1.5 Screening

It is recommended to use screened cables to reduce theradiation of electromagnetic noise into the environment andprevent malfunctions in the installation.

• Cable between the frequency converter output (U,V, W) and filter input (U1, V1, W1) to be screened ortwisted.

• Use preferably screened cables between the filteroutput (U2, V2, W2) and the motor. When

unscreened cables are employed it should beensured that the installation minimizes thepossibility of cross-couplings with other cablescarrying sensitive signals. This can be achieved bymeasures such as cable segregation and mountingin earthed cable trays.

• The cable screen must be solidly connected at bothends to the chassis (e.g. housing of filter andmotor).

• If IP00 filters are installed in cabinets and screenedcables are used, the screen of the motor cableshould be terminated at the cabinet cable entrypoint.

• All screen connections must exhibit the smallestpossible impedance, i.e. solid, large areaconnections, both ends of screened cable.

• Maximum cable length between frequencyconverter and output filter:Below 7.5kW: 2mBetween 7.5 - 90kW: 5-10mAbove 90kW: 10-15m

NOTEThe cable between frequency converter and filter should bekept as short as possible

NOTEMore than 10m is possible but Danfoss strongly discourgesuch installations, due to the risk of increased EMI andvoltage spikes on the filter terminals.

Illustration 5.3 Wiring Diagram

For F frame frequency converters parallel filters shall be used, one filter for each inverter module.The cables or bus bars between inverter and filter should have the same length for each module.The paralleling connection should be after the dU/dt filter/sine-wave filter, either at the filters' terminals or at the motorterminals.
