1 Introduction
1.1 Purpose of the Manual
These operating instructions provide information for safe
installation and commissioning of the filter.
The operating instructions are intended for use by
qualified personnel.
Read and follow the operating instructions to use the filter
properly, and pay particular attention to the safety
instructions and general warnings. Keep these operating
instructions available with the filter at all times.

1.2 Additional Resources
Resources available to understand advanced active filter
functions and programming:
•The VLT
®
Advanced Active Filter Service Manual
provides information on troubleshooting and
testing for field service technicians, as well as
disassembly and assembly instructions.
1.3 Product Overview
1.3.1 Working Principle
The VLT®Advanced Active Filter is used for harmonic
current mitigation and reactive current compensation. The
unit can integrate with various systems and applications as
a centrally installed filter or be combined with a VLT®
frequency converter as a packaged low harmonic drive
solution.

Illustration 1.1 Multiple Working Environments
The active shunt filter monitors all 3-phase line currents
and processes the measured current signal via a digital
signal processor system. The filter then compensates by
actively imposing signals in counter phase to the
unwanted elements of the current (harmonic distortion).
130BB718.10
Illustration 1.2 Active Filter Principles
The filter sets different IGBT switches in real time feeding a
DC voltage into the grid, which creates counter phase
signals. A built-in LCL filter smooths the compensated
current waveform, ensuring that the IGBT switching
frequency and DC component is not imposed to the grid.
The filter operates on generator or transformer supply and
can reduce individual motor loads, non-linear loads, or

AC coils to protect against overcurrent of the input diodes.

circuit

Illustration 1.3 Block Diagram
The filter allows either overall or selective harmonic
compensation modes. In overall compensation mode, all
harmonics are reduced. In this mode, the filter balances
the load to reduce uneven load distribution among the 3
phases. The steady state performance allows compensation
of harmonics to the 40th order, but the ultra-quick current
injection allows the filter to compensate flicker and other
quick and short-term phenomena. In selective mode, the
user can program acceptable individual harmonic levels
between 5th and 25th order. In selective mode, the filter
does not reduce harmonics in twos and threes, and does
not support phase load balancing and flicker reduction.
See parameter 300-00 Harmonic Cancellation Mode.
Program the filter priority as either reactive current or
harmonic compensation. If harmonic compensation is first
priority, the filter uses the current needed for harmonic
reduction and uses energy for reactive current correction
only if there is excess. The filter automatically and contin-
uously assigns energy between first and second priority to
provide the highest possible mitigation of both reactive
and harmonic compensation. The power factor is
optimised continuously and the supply transformer is used
to its maximum capacity. See parameter 300-01 Compen-
sation Priority.
The active filter has an optional RFI filter for Class A1 equal
to category C2.
1.3.2 IEEE519 Compliance
The active filter is designed to meet IEEE519 recommen-
dation for Isc/Il >20 for even individual harmonic levels.
The filter has a progressive switching frequency that
creates a wide frequency spread, giving lower individual
harmonic levels above the 50th harmonic level.

1.4 Ordering Information
1.4.1 Filter Configurator
Use the ordering number system to design an active filter according to the application requirements. For the VLT
®
Active
Filter AAF 006 Series, it is possible to order standard filters and filters with integral options by sending a type code string
describing the product to the local Danfoss sales office. For example: AAF006A190T4E21HXXGCXXXSXXXXAXBXCFXXXDX
This section describes each character in the type code. In the example, a standard 190 A active filter in an enclosure with
IP21 protection rating is selected for a 380–480 V net. The internet-based configurator configures the right filter for the right
application and generates a type code string. The configurator automatically generates an 8-digit sales number to be
delivered to the local sales office. It is also possible to establish a project list with several products and send it to a Danfoss
sales representative. The configurator can be found at www.danfoss.com/BusinessAreas/DrivesSolutions/.
