Deactivation of the variable pulse frequency
By changing the parameter p0290 to "0" or "1" the variable pulse frequency is deactivated.

Pulse frequency wobbling
Description
Pulse frequency wobbling is when the pulse frequency is varied slightly according to a
statistical process. The average pulse frequency value is still the value set; the statistical
variation of the instantaneous value results in a modified noise spectrum.
This procedure reduces the subjectively noticeable motor noise, especially for the relatively
low pulse frequencies set in the factory.
Pulse frequency wobbling is activated with p1810.2 = 1. The amplitude of the statistical
wobble signal can be set in the range of 0 % to 20 % via p1811.
