Control Parameter Settings
The following parameters cannot be adjusted by end users.
DO NOT use external modules to control the gimbal (including angle adjustment, speed adjustment and
gimbal center).
The Gimbal Balance Test, Gimbal Coaxiality Test, Gimbal Parameter Auto-tuning, Gimbal Force
Adjustment, and Reset Control Parameters are available on the Control Parameter Settings page of DA2
or the Gimbal Settings page of DJI Pilot app.
The following content uses the DA2 page as an example to describe setting operations.
Gimbal Balance Test
During Gimbal Balance Test, the three gimbal axis are in Joint Angle mode, and they can rotate at the
same speed within the mechanical limits in sequence. If the gimbal is out of balance, the gimbal output
will be changed under the inuence of gravity during rotation, so that any imbalances and the direction
of imbalances can be identied.
Here are the steps to the test:
1. Tap “Gimbal Balance Test” on “Gimbal Settings” page, and prepare the aircraft and gimbal according
to app instructions.
2. Run the test according to app instructions.
3. Gimbal Balance Test needs to be rerun if the gimbal is found to be out of balance based on test
progress and results. These adjustments maybe required:
a. Move the payload forward (backward) and upward (downward) and perform the balance test
again.
b. Adjust the position of the gimbal Roll arm to the left (to the right) and perform the balance test
again.
c. Adjust the position of the gimbal Yaw arm forward (backward) and perform the balance test again.
Gimbal Coaxiality Test
During Gimbal Coaxiality Test, the gimbal pitch-axis is in Joint Angle mode, and it can rotate at the same
speed within the mechanical limits. If the gimbal coaxiality is poor, the gimbal will not rotate smoothly at
certain positions during rotation, hence the test identies issues in gimbal coaxiality.
It is important to make sure the Gimbal Balance Test is finished and the gimbal is balanced before
performing the Gimbal Coaxiality Test
Here are the steps to the test:
1. Tap “Gimbal Coaxiality Test” on “Gimbal Settings” page, and prepare the aircraft and gimbal
according to app instructions.
2. Run the test according to app instructions.
