Setpoint Ramp Rates

Ramp rates limit your setpoint rate of change. Acceptable range: 10% per second (slow) – 1000% per second (fast).

Acceleration

% per Second

Deceleration

% per Second

Soft Start

Soft-start further limits the setpoint ramp rates when starting from zero. Acceptable range: 1–20 Seconds.

Temperature Limit

50–130°C

Capacity Limit (mAh)

Up to 99,000 (0 to bypass)

In the event that the above limits are reached, the controller will respond in the selected way.

Limiting Behaviour

Motor Beep

The motor will beep once every 10 seconds indicating the ESC is armed and ready.

Motor Braking

Brake On Stop

Applies the magnetic motor brake when drive is off.

Arming

Bypass Zero Throttle Requirement

Upon ESC reboot or loss of drive signal, the ESC will no longer require a zero throttle value to arm the motor.

Position Sensor

If your controller is equipped with a sensor, this will enable the sensor homing routine upon receiving a FULL POWER command on boot up.
