The injection current depends on F06.29 in the low frequency band (output frequency
<F06.28) and F06.33 in the high frequency band (output frequency> F06.32).
To get better results, the gain and integral time of the regulator can be adjusted.
Default settings can be used under normal circumstances.
They must not be adjusted by non-professionals.
