User Manual

The ESC measures temperature within the MCU and limits motor power if the
temperature is too high. Motor power is limited over a range:
– If the temperature is above the threshold, motor power begins to be limited.
– If the temperature is above the threshold plus approximately 150C, motor power is
limited to 25%.
Motor power is not limited below 25%.
Stall protection:
If the motor has attempted to start but not succeeded for a few seconds, it will stop
attempting and wait for throttle to be zeroed before attempting again.
Regenerative braking / active freewheeling:
Damped light mode is implemented by doing regenerative braking, and inherently active
freewheeling is also implemented.
Then losses due to braking are counteracted by the reduced losses of active
freewheeling.
Motor PWM:
The motor PWM frequency can be programmed between 16kHz and 48kHz. The
resolution is 2048 steps for MCUs running at 48MHz for a pwm frequency of 24kHz.
