Setting this to 1 will always target the highest energy peak. Setting this to 2 will target the highest energy peak that is lower in frequency than the highest energy peak. Setting this to 3 will target the highest energy peak that is higher in frequency than the highest energy peak.

Range	Units
10 - 495	hertz

INS_HNTCH_REF: Harmonic Notch Filter reference value¶

Note: This parameter is for advanced users

A reference value of zero disables dynamic updates on the Harmonic Notch Filter and a positive value enables dynamic updates on the Harmonic Notch Filter. For throttle-based scaling, this parameter is the reference value associated with the specified frequency to facilitate frequency scaling of the Harmonic Notch Filter. For RPM and ESC telemetry based tracking, this parameter is set to 1 to enable the Harmonic Notch Filter using the RPM sensor or ESC telemetry set to measure rotor speed. The sensor data is converted to Hz automatically for use in the Harmonic Notch Filter. This reference value may also be used to scale the sensor data, if required. For example, rpm sensor data is required to measure heli motor RPM. Therefore the reference value can be used to scale the RPM sensor to the rotor RPM.
