NEWTON 9
USER MANUAL
Pan Balance
The pan balance can be adjusted by turning the knob (point 7) on the back of the spine. Start by
loosening the pan lock (point 23), if the head is standing the spine will start to move sideways so its
important to prevent the head from tipping to the side. It’s recommended to have one person holding
the head while another do the pan adjustment to mitigate this risk.
By tipping the base of the head slightly to its side it should not move if the head is balanced. If the
back of the head moves to the opposite side it is back heavy and the knob should be turned clockwise.
If the moves to the other side the head is front heavy and the knob should be turned counter clockwise.
2.3 STARTING AND CONNECTING
Before turning on the Newton make sure everything is securely attached and that the system is balanced
as per the previous section. Also make sure batteries are properly attached or external power-in is
connected.
Turn on the Newton using the power switch (point 12). When starting up the system will perform
a calibration of the gyros to get the best possible performance. During this time the head should not
be moved. During the calibration the display will show mode “IMU CALIB”. If the IMU calibration
should fail, for example due to movement, the system will beep a number of times and show “IMU
BIAS CALIB FAILED” at the bottom of the display. The head is still usable but can have excessive
drift in all axes. To correct it, turn off the head and turn it on again to force another calibration.
The Newton is made to be controlled from the Dominion remote controller. For detailed infor-
mation on how to establish connection between them, either wireless or wired, please see “Dominion
User Guide”.
2.4 TUNING
When setting up the Newton, after attaching the camera and carefully balance it, the remote head needs
to be tuned for the specific setup to get good stabilization and avoid vibrations. The tuning depends on
on the mass distribution of the whole camera and lens package (including any other devices attached to
it) so while general guidelines and rough values can be provided for a specific setup, it is still required
that a full tuning is done after assembly.
Tuning is done through the user interface on the Dominion controller, in the settings menu, Re-
mote tuning tab. For each axis there are three principal tuning parameters and one auxiliary parameter.
The parameters are:
P Controls how strongly a disturbance or steering input is compensated. The main tuning parameter.
I Compensates for residual errors on longer movements.
D Dampens reaction to quick external disturbances.
Pos Gain Controls how quickly the head returns to correct position after a larger deviation.
The recommended procedure for tuning the Newton is as follows:
1. Make sure the remote head and camera is balanced and that nothing is loose or rattles
2. Set the P, I, and D for all axes to a low value. A good starting point is (4, 0.05, 0) for tilt, (3.5,
0.05, 0) for roll and (10, 0.05, 0) for pan
3. Doing one axis at a time, in the order tilt, roll, pan, tune:
3.1 Increase P until a high frequency oscillation begins, then back down to 80 % of the value.
Use the controller and move the axis from endpoint to endpoint, if oscillations begin at
any angle reduce the P value further
