GIMBAL CONFIGURATION

After the camera is balanced on the MIO, it’s time to fine tune some parameters for best performance.

Last updated 11 months ago

STIFFNESS TUNING

Stiffness setting has a significant impact on the performance of the gimbal. This setting adjusts the degrees to which the gimbal tries to correct for unwanted camera movement and hold the camera stable. The higher you can run the setting without vibration or oscillation, the better.

GENERAL METHOD

Start with a low value of 20 for all axes then turn motors ON. Slowly increase this setting until you feel an oscillation in each axis, then reduce it until the oscillation subsides. You can touch the camera to feel the oscillation during tuning. Increase the stiffness setting 5-10 points at a time until oscillation appears then reduce 5 points until oscillation subsides.

STEP 01 - TILT STIFFNESS

Slowly increase this setting until you feel an oscillation in the tilt axis, then reduce the setting until the oscillation subsides. Make sure there is no vibration when tilting the camera up and down and when moving the gimbal in any orientation.

STEP 02 - ROLL STIFFNESS

Slowly increase this setting until you feel an oscillation in the roll axis, then reduce the setting until the oscillation subsides. Pick the gimbal up and make sure there is no vibration when you move the gimbal around.

STEP 03 - PAN STIFFNESS

Slowly increase this setting until you feel an oscillation in the pan axis, then reduce the setting until the oscillation subsides. Tilt the gimbal about 20 degrees from the vertical and make sure that no vibrations are presented.

FILTER

The purpose of the filters is to eliminate noise and vibration due to structural resonances in the camera, lens, or gimbal.

Setting the filters too high or too low can cause signal disturbances that can reduce the overall stabilization.

GYPRO FILTER

Defines the strength of the filter applied to Gyro sensor output. If the gimbal has oscillations that cannot be corrected by adjusting stiffness settings, the Gyro Filter is used to further tune the gimbal and remove the oscillation

OUTPUT FILTER

Defines the strength of the filter applied to motor output. If the gimbal has oscillations that cannot be corrected by adjusting stiffness settings, the Output Filter is used to further tune the gimbal and remove the oscillation.

  1. If the gimbal is vibrating at a high frequency after tuning, increase the filter values.

  2. If the gimbal is oscillating or rocking at a low frequency after tuning, decrease the filter values.

EXPERT / ADVANCED SETTINGS

There are some expert parameters that normally do not need to be adjusted. Leave these parameters at default settings unless they are required for troubleshooting.

HOLD STRENGTH

  • If “Auto power adjustment” is enabled, “Hold strength” will be the minimum power level required for the corresponding axis. The controller will automatically adjust power level from minimum to maximum level depending on the displacement between the current angle and commanded angle.

  • If “Auto power adjustment” is not selected “Hold strength” will be a constant power level provided to the corresponding axis and should be adjusted manually. This option is only recommended for advanced users.

For heavy cameras, it’s suggested to increase hold strength for each axis around 10% than the default value. If “Auto power adjustment” is not selected “Hold strength” will be fixed power level provided to the corresponding axis and should be adjusted manually. This option is only recommended for advanced users.

GAIN

Defines how fast each axis will return to commanded position. To reload default expert settings just press “Default” in the expert menu.

DEFAULT SETTINGS

PREDEFINED PROFILES

For specific cameras, there is a list of predefined profiles that stores the suitable settings such as stiffness, gyro filter, output filter, hold strength, gain… accordingly . The predefined profile is made to best suit with specific camera and enable optimized performance without spending time tuning the gimbal.
