# FAQ

<details>

<summary>Why is my gimbal vibrating or producing noise from the motors?</summary>

This may be due to overly stiff motor settings. Try reducing the **Stiffness** value **by 5 units gradually** until the vibration or noise disappears.

<summary>Why doesn’t my gimbal have the Auto-Tune feature?</summary>

Some gimbals like **SM** or **MR** have **dedicated profiles for each lens**, and therefore Auto-Tune is not available. These profiles are optimized manually for best performance.

<summary>My Pan axis is drifting. What should I do?</summary>

First, check the **gimbal mode**:

* If you are using **Lock Mode**, the Pan axis may **drift slightly (up to \~1 degree per minute)**.
* To avoid this, we recommend switching to **Follow Mode** and setting the **Window Angle to 0**

<summary>My Roll axis is drifting. What causes this?</summary>

This is often due to environmental changes. Please perform a **GYRO Calibration 2–3 times**. Drift on the Roll axis usually occurs when moving between different working environments.

<summary>What are the conditions for the drone angle reference function?</summary>

* The drone sends attitude data to the gimbal: Your drone needs to be configured to transmit its attitude messages to the gimbal, specifically either `AUTOPILOT_STATE_FOR_GIMBAL_DEVICE (286)` or `ATTITUDE (30)`.
* Enable Pan Drift in gTune: You'll need to activate the "Pan Drift" feature within the gimbal's gTune software.

Please set up conditions that are satisfied; the gimbal will automatically utilize the drone's data to compensate for and minimize the yaw drift you've observed.&#x20;
