Warnings
The Danfoss harmonic filter AHF 005 and
AHF 010 contain dangerous voltages
when connected to line voltages. Only a
competent electrician should carry out the
electrical installation. Improper installation of the filter module or the connected
frequency converter may cause equipment failure, serious injury or death. Follow this manual and National Electrical
Codes and local safety codes.
Operation of the harmonic filter is only allowed with a closed cover of the housing!
Symbols used in this manual
When you read this manual you will come across different symbols that require special attention. The symbols used are the following:
Warning of hazardous electrical voltage
Warning of a general danger
NB!
This note designates general, useful
notes. If you observe it, handling of the filter module / drive system is made easier.
Operator's safety
After mains disconnections, the power terminals X1.1, X1.2, X1.3, X3.1, X3.2, X3.3,
X4.1, X4.2 and X4.3 remain live for minimum 4 minutes.
The filter modules have to be installed in
a way, that they fulfil their function and
don’t expose persons to danger. They
have to be mounted correctly and used in
accordance with their purpose.
Avoid filter module damage
1. The filter modules are to be used only with
Danfoss frequency converters. The usage
with other electrical loads is not permitted
and may damage the devices.
2. Don’t use the drive system (frequency converter, motor load and filter module) if the
equipment has been damaged.
3. Modifications of the filter modules are not allowed.
DC-link resonance
To avoid resonance’s in the DC-link, it is possible to
disable the dynamic DC link compensation.
483 Dynamic DC link compensation
(DC link comp.)
Value:
Off [0]
On [1]
Function:
The VLT 5000, 6000 and 8000 series include a feat ure,
which ensures that the output voltage is independent
of any voltage fluctuation in the DC link, e.g. caused
by fast fluctuation in the mains supply voltage. The
benefit is a very steady torque on motor shaft (low torque ripple) under most mains conditions.
Description of choice:
In some cases this very dynamic compensation can
cause resonance’s in the DC link and should then be
disabled. Typical cases are where a line choke or a
passive harmonic filter (e.g. filters AHF005/010) is
mounted in the mains supply to the frequency converter to suppress harmonics. Can also occur on
mains with low short circuit ratio.

Description
The Danfoss harmonic filters AHF 005 and AHF 010
are ensuring near sinusoidal line current minimising
the harmonic current emission into the mains supply.
The Danfoss AHF 005 and AHF 010 are advanced
harmonic filters not to be compared with traditional
harmonic trap filters. The Danfoss harmonic filters
have been specially designed to match all the Danfoss
frequency converters. The filters AHF 010 and AHF
005 are available in four voltage ratings.
• 380 - 415 V AC, 50 Hz
• 440 - 480 V AC, 60 Hz
• 500 - 525 V AC, 50 Hz
• 690 V AC, 50 Hz
The Danfoss AHF 010 and AHF 005 have the following
characteristics:
• Small compact housing that fits into a panel
• Easy to use in retrofit applications
• AHF 010 reduces the total harmonic current
distortion to 10%*
• AHF 005 reduces the total harmonic current
distortion to 5%*
• Current rating from 10A - 370A
• For higher power modules can be paralleled
• One filter module can be used for several frequency converters
• High efficiency (> 0.98)
• User-friendly commissioning - no adjustment
necessary
• No routine maintenance required
* THiD of 10% or 5% will be achieved when the following conditions are met:
-
THvD of the system without the drive operating is less than 2%
-
Filter is operating at nominal load
If these conditions are not fulfilled, a significant reduction of the harmonic components can still be achieved,
but the rated THiD values may not be achieved.

• Please note that the matching of the typical Danfoss frequency converter and filter is pre-calculated based on
400V and assuming typical motor load (4 or 2 pole motor). VLT 5000 series is based on a max. 160 % torque
application, while VLT 6000 and 8000 series are based on a max. 110% torque application.
The pre-calculated filter current may be different than the input current ratings of VLT 5000, VLT 6000 and VLT
8000 series as stated in the respective operating instructions, as these numbers are based on different operating
conditions.

Calculation of the exact filter size needed
For optimal performance the harmonic filter should be
sized for the line input current to the frequency converter, i.e. the input current drawn based on the expected load of the frequency converter and not the size
of the frequency converter itself!
The line input current to the frequency converter
(I
FC,L
) can by calculated using the nominal motor cur-
rent (I
M,N
) and displacement power factor (Cos φ)) of
the motor. Both data are normally printed on the nameplate of the motor. In the case where the nominal motor
voltage (U
M,N
) is unequal to the actual line-line voltage
(U
L
) the calculated current must be corrected with the
ratio between these voltages as shown in the equation
below.
The harmonic filter chosen must have a nominal current (I
AHF,N
) equal to or larger than the calculated
frequency converter line input current (I
FC,L
).
If several frequency converters are to be connected to
the same filter, the harmonic filter must be sized according to the sum of the calculated line currents.
If the harmonic filter is sized for the load,
and the motor of the corresponding frequency converter is changed, the current
must be re-calculated to avoid overload of
the harmonic filter.
