Frequency response measurement Frequenzgangmessung
Application:
Verification of the disturbance value behavior of the velocity control
Which velocity deviation generates a sinusoidal disturbance torque / disturbance
current with the frequency fZ ?
The frequency response of the compliance corresponds to the disturbance step
response in the time range
Other settings
(1) Excitation
Serves to set the excitation signal of the frequency response measurement.
(2) Permissible following error (only for frequency response measurement)
The resulting following error is increased by the injection of the excitation signal
during the frequency response measurement. In order to allow for this, the
permissible following error window can be enlarged so that the measurement can
be made. After the end of the measurement, this is reset to the original value.
(3) Selection of the kind of analysis of the measurement results
Depending on the fact whether frequency spectra or frequency responses are
measured, the following types of analyses are available:
For frequency spectra:
(a) Spectrum
(b) Spectrum cumulated
(c) cascade diagram
For frequency responses:
(d) noise frequency response
(d) noise frequency response cumulated
