Description
Enables the noise smoothing function. Noise smoothing
distributes the acoustic motor noise over a range of
frequencies instead of a single tonal frequency resulting in
lower peak noise intensity. A random component with an
average of 0 Hz is added to the switching frequency set by
parameter 2606 SWITCHING
Note: Parameter has no effect if parameter
SWITCHING FREQ is set to 16 kHz.
