Settings

Settings that should be considered when getting started. Settings can be changed over USB-C or DroneCAN.
A recommended settings list is compiled below, which must be considered for all new systems and setups. They cover recommended minimum motor drive options, communications and behaviour during a fault condition.
Please make sure to consider all of the following settings! We see them as the essential minimum, and it's important not to overlook them.

Getting Started Settings
The settings below are recommended focus points for a given system. They should be changed depending on the requirements. Settings can be accessed over USB-C and CAN interfaces.
DroneCAN Settings
Setting Name
Default Value
Description
CAN Bus Enabled
ON
CAN Bus communication is enabled. The ESC will use DroneCAN for control and telemetry. The input of DShot and PWM is disabled. Disabling this setting enables other protocols.
AFW Enabled
ON
Active Freewheeling (AFW) enables regenerative braking. The result is far greater linearity on ESC output, alongside increased efficiency. Must be disabled for use with power supplies or systems that cannot handle regenerative current (eg. tethers).
Normal Rotation
ON
Output rotation direction. Toggling this setting reverses the output direction without requiring cabling modification.
Motor Pole Pairs
1
The number of pole pairs on the attached motor. Utilised for scaling the RPM telemetry to the correct values. No other impact on the motor drive.
DroneCAN ESC Index
0
ESC channel as per flight controller output number. Determines ESC position within the system/aircraft. 
Protection Behaviour Settings
A list of settings that affect the primary protection mechanisms can be found below. The behaviour upon triggering will likely change between setup requirements, so all should be considered.
Setting
Default Value
Description
Signal Timeout Period
500 ms
If no valid signal is present for this period of time, the output drive will be automatically shut down. The drive will be resumed once a valid signal is returned and the throttle is 0%. 
Overvoltage Response
Limit Duty Cycle
The behaviour once the overvoltage threshold is passed on bus voltage. The normal drive will resume once the voltage settles below the limit. The default response will slowly limit the output power until the event clears.
Undervoltage Response
Limit Duty Cycle
The behaviour once the undervoltage threshold is passed on bus voltage. The normal drive will resume once the voltage settles above the limit. The default response will slowly limit ramp-up power until the event clears.
Require Zero Throttle
OFF
Override the requirement for 0% throttle in the event the signal is lost and returned. Requires CANBUS control to be active. The unit will still require zero throttle on boot to start drive.
Over Temperature Response
Power Limit 50%
The behaviour once the temperature limit is exceeded on the drive. The default is to reduce the output power to 50%. The normal drive will resume once the temperature is reduced below the limit.
