4.3.7 Motor filter
For the reduction of harmonic waves motor filters in the form of motor
choke or LC-sinusiodal filters are used in certain applications.
Sinusoidal filter
In the regulation of synchronous machines the use of sinusoidal filters for
the reduction of harmonic waves is supported. The capacitance value is
entered under "Sine filter". If only a motor choke is used, this must be
entered in the field "Motor choke", irrespective of the motor type.
4.3.8 Switching
frequency
For high frequency applications the switching frequency of the output
stage should be at least 10 times the value of the output frequency.
The switching frequency can be selected under "Control - output stage".
Please observe the permissible current load of the output stage for the
different switching frequencies (see appendix A1).
