When [`FW_AT_SYSID_TYPE`](../advanced_config/parameter_reference.md#FW_AT_SYSID_TYPE) is set to linear/logarithmic sine sweep (recommended), the max rates are approximately 45 deg/s for roll and 30 deg/s for pitch and yaw.
The progress is shown in the progress bar, next to the _Autotune_ button.

By default, the autotune maneuvers ensure that a sufficient angular rate is reached for system identification. The target rates are approximately 45 deg/s for roll and 30 deg/s for pitch and yaw.
By default, the autotune maneuvers ensure that a sufficient angular rate is reached for system identification, corresponding to 75% of the configured maximum roll (`FW_R_RMAX`), pitch (`FW_P_RMAX_NEG`, `FW_P_RMAX_POS`) and yaw (`FW_Y_RMAX`) rates.
If the signal-to-noise ratio of the vehicle is low, the system identification algorithm might have issues finding the correct coefficients. Ensure that there is no excessive noise and/or platform vibration.
