There are Stiffness, Strength, Filter and Control settings in the motor settings page. Stiffness
should always be adjusted in accordance with the total payload mounted onto the gimbal,
and the others are advanced settings. It is recommended to leave the settings as default.
Stiffness: The motor stiffness adjustment allows you to fine-tune the amount of power that
is applied by the motors as they react and balance the weight on each axis. Please make
sure you leave an extra margin for this setting to ensure stability at all times.
Auto Tune: Stiffness value is determined by the gimbal system according to the payloads
of the gimbal. There are three tuning aggressiveness profiles so you can adjust the
calculated stiffness value with ease. For most cases, we recommend using the ‘Mid’ or
‘High’ profile for the best robustness. For scenarios where you need to move slowly with a
more mellow feel, you can use the ‘Low’ profile.
For example, when the payload is 1.8 kg, a ‘High’ Stiffness value provided by Auto Tune
may come out to 45, so selecting the ‘Mid’ results in a Stiffness value of 36, and selecting
the ‘Low’ results in a Stiffness value of 27.
After selecting the tuning profile, simply tap ‘Auto Tune’. The Ronin-S will automatically
work out the optimal result based on the weight of the setup. Alternatively, you can press
and hold Ronin-S’ M button and front trigger simultaneously for four seconds to start Auto
Tune without using the App.
The Auto Tune process takes approximately 40 seconds. After Auto Tune, you can see
detailed motor diagnostics at the bottom of the page. If the gimbal is properly balanced,
the Power value of the motors should be in the range of ±5. If Power consumption on
