2.1.1 CE Conformity and Labelling
What is CE Conformity and Labelling?
The purpose of CE labelling is to avoid technical trade obstacles 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.
The low-voltage directive (73/23/EEC)
Frequency converters must be CE labelled in accordance with the low-voltage directive of January 1, 1997. The directive applies to all electrical equipment
and appliances used in the 50 - 1000 V AC and the 75 - 1500 V DC voltage ranges. Danfoss CE-labels in accordance with the directive and issues a
declaration of conformity upon request.

2 Safety and Conformity
Output Filters Design Guide
Warnings
When in use the filter surface temperature rises. DO NOT touch the filter during operation.
2
Never work on a filter in operation. Touching the electrical parts may be fatal - even after the equipment has been disconnected from
the drive or motor.
Before servicing the filter, wait at least the voltage discharge time stated in the Design Guide for the corresponding VLT® to avoid
electrical shock hazard
NB!
Never attempt to repair a defective filter

3 Introduction to Output Filters
3 Introduction to Output Filters
3.1 Why use Output Filters
This chapter describes why and when to use Output Filters with Danfoss Drives frequency converters.

3.2 Which Filters for which Purpose
The table 3.1 below shows a comparison of du/dt and Sine-wave filter performance. It can be used to determine which filter to use with your application.
Performance criteria
Motor insulation stress
Motor bearing stress
EMC performance
Max. motor cable length
du/dt filters
Up to 100 m cable (screened/unscreened) complies
with the requirements of IEC60034-17 (general purpose motors). Above this cable length the risk of
“double pulsing” increases.
Slightly reduced, only in high-power motors.
Sine-wave filters
Provides a sinusoidal phase-to-phase motor terminal voltage. Complies with IEC-60034-17* and NEMA-MG1 requirements for general purpose motors with cables up to
500 m (1 km for frame size D and above).
Reduces bearing currents caused by circulating currents.
Does not reduce common-mode currents (shaft currents).
Eliminates motor cable ringing. Does not change the Eliminates motor cable ringing. Does not change the emisemission class. Does not allow longer motor cables as sion class. Does not allow longer motor cables as specified

*) Not 690 V.
3.2.1 du/dt Filters
du/dt filters cut off frequencies are above the switching frequencies. They consist of inductors and capacitors in a low-pass filter arrangement. The
inductance (L) and capacitance (C) values are shown in the tables in the section Electrical Data - du/dt Filters in the chapter Selection of Output
Filters. They have lower L and C values, thus they are cheaper and smaller than Sine-wave filters
Features and benefits
du/dt filters reduce the voltage peaks and du/dt of the pulses at the motor terminals. The voltage at the motor terminals is still pulse-shaped, as shown
in the figure (voltage waveform). The motor current has a sinusoidal shape without commutation spikes.
The role of the du/dt filters is to protect the motor insulation against premature ageing and flashover.

Illustration 3.1: Without filter
Illustration 3.2: With du/dt filter
Advantages:
•
Protects the motor against high du/dt values and voltage peaks hence prolongs the lifetime of the motor
•
Allows the use of motors which are not specifically designed for converter operation, for example in retrofit applications
Application areas:
The typical application areas for du/dt filters are:
•
Applications with frequent regenerative braking
•
Motors that are not rated for frequency converter operation and fed through very short motor cables (less than 15 meters)
•
Motors placed in aggressive environments or running at high temperatures
•
Applications with risk of flash over
•
Installations using old motors (retrofit) or general purpose motors not complying with IEC 600034-17
•
Applications with short motor cables

Illustration 3.3: Measured du/dt values (rise time and peak voltages) with and without du/dt filter using 15 m, 50 m and 150 m cable lengths
on a 400 V, 37 kW induction motor.
The du/dt value decreases with the motor cable length whereas the peak voltage increases (see Illustration 3.3). Therefore it is recommended to use
du/dt filters only in applications with cable length up to 150 meters. Above 150 meters Sine-wave filters are recommended.
Filter features:
•
IP00 and IP20 enclosure in the entire power range
•
Side by side mounting with the drive
•
Reduced size, weight and price compared to the sine-wave filters
•
Possibility of connecting screened cables with included decoupling plate
•
Compatible with all control principle including flux and WC+
•
Filters wall mounted up to 115 A and floor mounted above that size
3.2.2 Sine-wave Filters
The Danfoss Drives sine-wave filters are designed to operate with the VLT® FC Series Drives. They replace the LC-filter product range and are backwards
compatible with the VLT 5000-8000 Series Drives. They consist of inductors and capacitors in a low-pass filter arrangement. The inductance (L) and
capacitance (C) values are shown in tables in the section Electrical Data - Sine wave Filters in the chapter Selection of Output Filters.
Features and benefits
Sine-wave Filters reduce motor insulation stress and eliminate switching acoustic noise from the motor. Bearing stress is also reduced, especially in larger
motors, above 50 kW. The filter does not act between motor phases and ground. This means that the motor cable length is limited by the leakage current.
The motor losses are reduced because the motor is fed with a sinusoidal voltage, as shown in illustration 3.5. Moreover, the filter eliminates the pulse
reflections in the motor cable thus reducing the losses in the frequency converter.
Advantages:
•
Protects the motor against voltage peaks hence prolongs 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 motor cables by eliminating high frequency ringing in the cable
•
Reduces electromagnetic interference from unscreened motor cables
•
Reduces the bearing current thus prolonging the lifetime of the motor

5 How to Install
5.1 Mechanical Mounting
5.1.1 Safety Requirements of Mechanical Installation
Pay attention to the requirements that apply to integration and field mounting kit. Observe the information in the list to avoid serious
damage or injury, especially when installing large units.
The filter is cooled by natural convection.
To protect the unit from overheating it must be ensured that the ambient temperature does not exceed the maximum temperature stated for the filter.
Locate the maximum temperature in the paragraph Derating for Ambient Temperature.
5
If the ambient temperature is in the range of 45 °C - 55 ° C, derating of the filter will become relevant.
5.1.2 Mounting
•
Mount the filter vertically with the output (motor side) at the bottom (in case of wall-mount).
•
Do not mount the filter close to other heating elements or heat sensitive material (such as wood)
•
The filter can be side-mounted with the frequency converter. There is no requirement for spacing between the filter and frequency converter.
5.1.3 Earthing
The filter must be earthed before switching the power on (high leakage currents).
Common mode interferences are kept small by ensuring that the current return path to the VLT has the lowest possible impedance.
•
Choose the best earthing possibility (e.g. cabinet mounting panel)
•
Use the enclosed (in accessory bag) protective earth terminal to ensure the best possible earthing
•
Remove any paint present to ensure good electrical contact
•
Ensure that the filter and VLT make solid electrical contact (high frequency earthing)
•
The filter must be earthed before switching the power on (high leakage currents)

5 How to Install
Output Filters Design Guide
5.1.4 Screening
It is recommended to use screened cables to reduce the radiation of electromagnetic noise into the environment and prevent malfunctions in the
installation.
•
•
Cable between the VLT output (U, V, W) and filter input (U1, V1, W1) to be screened or twisted.
Use preferably screened cables between the filter output (U2, V2, W2) and the motor. When unscreened cables are employed it should be
ensured that the installation minimizes the possibility of cross-couplings with other cables carrying sensitive signals. This can be achieved by
measures such as cable segregation and mounting in earthed cable trays.
•
The screen on screened cables must be solidly connected at both ends to the housings (e.g. housing of filter and motor).
•
All screen connections must exhibit the smallest possible impedance, i.e. solid, large area connections, both ends of screened cable.
•
For maximum cable length consult the Design Guide of the VLT in question

Output Filters Design Guide
6 How to Programme the Frequency Converter
6 How to Programme the Frequency Converter
•
The VLT® switching frequency must be set to the value specified for the individual filter. Please consult the VLT® Programming Guide for the
corresponding parameter values.
•
•
With an output filter installed only a reduced Automatic Motor Adaption (AMA) can be used.
The filters are designed for a max. frequency of 100/120 Hz (up to 10 A). For frequencies above 50 Hz the nominal current may have to be
reduced (see filter nameplate).
Sine-wave filters can be used at switching frequencies higher than the nominal switching frequency, but should never be used at switching frequencies
with more than 20% lower than the nominal switching frequency.
du/dt filters, unlike Sine-wave filters, can be used at lower switching frequency than the nominal switching frequency, but higher switching frequency
will cause the overheating of the filter and should be avoided.
