Please note that the matching of the typical Danfoss adjustable frequency drive and filter is pre-calculated

based on 500V and assuming typical motor load. VLT 5000 series is based on a 160 % torque application,
while the VLT 8000 series are based on 110% torque application.
The pre-calculated filter current may vary from the input current ratings of VLT 5000 and VLT 8000 series as
stated in the respective instruction manuals, 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 adjustable

frequency drive, i.e. the input current drawn based on

the expected load of the adjustable frequency drive

and not the size of the adjustable frequency drive itself!

The line input current to the adjustable frequency

drive (I

FC,L

) can by calculated using the nominal motor

current (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 adjustable

frequency drive line input current (I

FC,L

).

If several adjustable frequency drives 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 adjustable

frequency drive is changed, the current must

be re-calculated to avoid overload of the harmonic filter.
