The zero-throttle requirement is enabled by default. When this is active, the controller will only arm if it first receives a zero-throttle signal—such as at startup or after recovering from an error. Once armed, throttle input will control the motor as expected.

:::hint{type="danger"}
When this setting is enabled, to recover from signal loss or error states, zero throttle MUST be commanded.

If you disable this option, the controller can arm without first seeing zero throttle.

Note: This requirement is automatically ignored when recovering from a software crash.

::::hint{type="warning"}
PWM signalling has a separate zero throttle requirement under certain conditions as described here:
