8kHz:
Is the PWM Frequency for a motor with 2 poles, usually an inrunner motor.
However, the 16 kHz frequency can provide more power but will also cause more
Electromagnetic Interference (EMI). Therefore, the default setting is 8kHz.
16kHz:
Is the PWM frequency for a motor with more than 2 poles, usually an
outrunner motor.
10. Protection Mode for Low Voltage: Reduce Power / Hard Cutoff
Reduce Power:
The ESC will reduce the motors output power when the set
“Low Voltage Protection” mode is reached to protect the battery from over discharging
but still giving enough power to return the ESC. This parameter is recommended.
Hard Cutoff
: The ESC will completely shut off the motors ouput power when the
set “Low Voltage Protection” mode is reached to protect the battery from over
discharging.
Start-up Protection
If the motor fails to startup normally in two seconds after push the throttle to start the ESC will
cut off the motor. The throttle shall be reset to commence a restart. Possible reasons: there is a
disconnection or poor contact in wiring between the ESC and motor. The propeller is stemmed
by other objects. The speed reduction gear is badly blocked.
Overheat Protection
When the working temperature in the ESC is higher than 100
℃
, the ESC will reduce the output
power automatically to commence protection, but will reduce the output power to 40% of full
power to reserve some power for motor and avoid crash landing instead of turning off all output
power. The ESC will recover to max power as the temperature falls.
Loss of Throttle Signal Protection
The ESC will reduce the output power to motor when the ESC detect that there are 2 seconds'
lost of throttle signals. If there another 2 seconds' lost of throttle signals, the ESC will cut off
motor automatically. If the throttle signals recover during the Throttle Signal reduction of output
power of motor, the ESC will recover control of throttle at once. In this method, in the case of
momentary lost of signals (within 2 seconds), the ESC Loss Protection will not commence the
protection of throttle. Only when the control signals have been lost for a long time, the ESC will
