Using the Software PC/MAC PID control
10. After you have optimally set the PID
parameter for all axes in a static state, move
the Gimbal in all directions, as in later real
use. If you can still determine vibrations due
to the mutual interaction of the three axes in
certain positions, reduce the PID values
slightly for the axis that is still disruptive.
Certain resonance vibrations, which can be caused by the interaction between your camera and the
mechanical structure of the Gimbal, cannot be reduced as necessary by setting the PID control parameter.

Note
Tip!
In the view level “DEVELOPER” it is possible to temporarily disable the
axis motors, on which you could not conduct a PID fine-tune, to ensure that
they do not irritate with additional vibrations during the process. But ensure that
you do not alter other settings in the view level “DEVELOPER”. Note the
assigned motor designation before you disable it so that you can then assign it
correctly again and reactivate it later.
Note
Tip!
Find out which axis is causing the most vibrations. To do this go to the
register card Monitoring” on the user surface (GUI). First select “Receive
extended debug info” by marking the check box, so the parameters
FREQ_ERR und RMS_ERR can be seen. With FREQ_ERR you will find the
interfering frequency. With RMS_ERR you can find out easily the axis, which
causes the interfering frequency.
Note
Function!
During the adjustment hold the device vertically and in a stable
position in your hand, preferably supported by a solid surface (table surface,
tripod, etc.).
Note
Function!
Before you begin the automatic fine-tuning process with the PID
control parameter, ensure that the camera is balanced, the gyrometer and
accelerometer are calibrated and the PID gain multiplier is set for all 3 axes
to the standard 1.0. The Gimbal has to be completely still and free of
vibrations (e.g. tripod), camera horizontally aligned and there should be
sufficient freedom of movement that every axis can turn approx. 20-30°.
