Comparison of integrated and external RFI lters
RFI lters Filter types
Integrated in the inverter External
Low Leakage Short Distance Long Distance
Use In standard applicaons. In mobile systems. With short cable length. At switching frequencies
4 kHz and 8 kHz.
Opmisaon Easy use. For low leakage current. For low leakage current. For long motor cable.
Reduces noise emissions Cable-guided and radiated Cable-guided Cable-guided Cable-guided

Sine lter
A sinusoidal lter in the motor cable limits the rate of voltage rise and the capacive charge/
discharge currents between the conductors that occur during inverter operaon.
Only use a sinusoidal lter with standard asynchronous motors 0 to 550 V.
Operaon only with V/f or square-law V/f characterisc control.
Set the switching frequency permanently to the specied value.
Limit the output frequency of the inverter to the given value.

Power supply units
For the external supply of the control electronics of the inverter.
The parameterisaon and diagnoscs can be executed when the mains input at the inverter is
deenergised.
