The following beep tones are present during unit operation as an extra form of diagnostics parallel to the status LED. Beeps will only sound if a motor is connected and there is sufficient voltage to drive. Beeps can be disabled through unit configuration.

Beep groupings can be disabled individually.

### DroneCAN Beep Command

ESCs respond to the DroneCAN beep command [1080.BeepCommand.uavcan](https://github.com/dronecan/DSDL/blob/master/uavcan/equipment/indication/1080.BeepCommand.uavcan) by playing an identify beep.
