Ordering Numbers, 690V, 50Hz; Calculation Of The Exact Filter Size Needed - Danfoss AHF 005 Operating Instructions Manual

2 Ordering Numbers
⋆ Please note that the matching of the typical Danfoss frequency converter and filter is pre-calculated based on 500V and assuming typical motor
load. FC 300 is based on an 160% torque application, while FC 100 and FC 200 series are based on 110% torque application.
The pre-calculated filter current may be varying from the input current ratings of FC 100, FC 200 and FC 300 series as stated in the respective
operating instructions, as these numbers are based on different operating conditions.

2.1.7 Calculation of the Exact Filter Size Needed

NB!
For optimal performance the harmonic filter should be sized for the mains 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 harmonic filter chosen must have a nominal current (I
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 mains
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.
