3.4.8.4 Description of the Ks measurement parameters
52.1
Command status
Value 1 starts the Ks measurement via the acceleration and braking procedure and via
the value 40 the FFT module is started. If the Ks measurement starts both axes via the
FFT module then the axis remains in the waiting state until the other axis has finished and
then starts automatically because the FFT module exists once only. Additionally the
speed controller parameter in dependence of the phase reserve, the PWM frequency, the
sampling time and encoder smoothing can be calculated.
The current status is also displayed here.
