Creating the transfer function
The oscilloscope automatically records the amount and phase response of the
controller according to the controller settings. This produces an initial estimate of the
control quality.
To determine the transfer function the noise amplitude (motor rated current) and the
sampling time (default 0.125 ms) must be specified. Click the "Start Test Signal"
button.
