7.1 Reactor and filter
Line reactor
The purpose of a line reactor is to reduce line-side harmonic currents and harmonic effects.
This applies particularly in the case of weak power supplies (network short-circuit power uK
> 1 %).
Line filter
The Power Module complies with a higher radio interference class when an additional line
filter is used.
Output reactor
Output reactors reduce the voltage loading on the motor windings. At the same time, the
capacitive charge/discharge currents, which place an additional load on the power section
when long motor cables are used, are reduced.
Sine-wave filter
The sine-wave filter is designed to limit the rate of rise of voltage and the capacitive charge
or discharge currents which usually occur with inverter operation.
