
(1) start frequency
This is the smallest frequency at which is still measured. During the measurement

of frequency spectrum and noise frequency response this results automatically
from the bandwidth and is only displayed as an information.
(2) End (bandwidth)
This corresponds to the highest frequency which is measured. Start frequency as

well as the frequency resolution can be varied with the aid of the bandwidth for
frequency spectrum and noise frequency response.
(3) Frequency resolution (see on page 256)
During the measurement of frequency spectrum and noise frequency response

this results automatically from the bandwidth and is only displayed as an
information.

Speed control

Closed velocity control
Shows the dynamic behavior of the closed velocity control.
=> How a signal on the velocity demand value is transmitted to the velocity actual
value.
