Features 1、Closed Loop P gain closed-loop proportional gain: Set proportional gain for speed control return/ loop. This setting controls the gain from the speed error to the motor power 2、(Closed Loop I gain) Closed-loop integral gain: Set integral gain for speed control return/ loop.

This function is effective only for PWM input and invalid for PPM input. Note: Low multi-axis gain will also limit the maximum power transmission to the motor 4、Start-up: Always use direct boot mode. Direct start-up mode from the beginning of the use of back EMF detection to drive the motor. In this mode, the throttle size determines the power, but there is a limit to the maximum level/ value.

Generally speaking, the mid-angle can be, if there is a motor block, it can be improved by adjusting the angle Specification Features: 1. Closed Loop P gain closed-loop proportional gain: Set proportional gain for speed control return/ loop. This setting controls the gain from the speed error to the motor power. 2. (Closed Loop I gain) Closed-loop integral gain: Set integral gain for speed control return/ loop. This setting controls the gain between the integrated speed error (the total amount of time period) and the motor power. 3. (Closed loop mode)Closed-loop mode: Set the speed range for control return/ loop operation, take a pair of polar motors as an example: High range: Throttle value from 0% to 100% (rising in a straight line) corresponding to the speed target from 0 to 200000 electrical speed. Medium range: Throttle value from 0% to 100% (rising in a straight line) corresponding to the speed target from 0 to 100000 electrical speed. Low range: Throttle value from 0% to 100% (straight up) corresponding to the speed target from 0 to 50000 electrical speed. Close: When the closed-loop mode is set to close, the control return/ loop is disabled. 4. Multi gain: The power applied to the motor in proportion to the given input. This function is effective only for PWM input and invalid for PPM input. Note: Low multi-axis gain will also limit the maximum power transmission to the motor. 5. Start-up: Always use direct boot mode. Direct start-up mode from the beginning of the use of back EMF detection to drive the motor. In this mode, the throttle size determines the power, but there is a limit to the maximum level/ value. The maximum level/ value can be controlled by starting power parameters. Note: too high start power setting can lead to electric adjustment or motor overload! 6. Commutation timing: It can be adjusted in five steps:0 ° low,8 ° medium low,15 °,23 ° medium high and 30 ° high. Generally speaking, the mid-angle can be, if there is a motor block, it can be improved by adjusting the angle. 7. PWM frequency: High PWM frequency: about 20 kHz. Low PWM frequency: about 8 kHz. PWM Damped Light mode: Accelerate the deceleration by increasing the loss to the motor. This mode is usually used with a high PWM frequency. This mode is supported only if the Mos switch on the switch is fast enough. 8. (Pwm dither) PWM high frequency pulsation: This parameter increases the pulsation to the motor according to the PWM closing cycle time. It can reduce the speed range (similar to throttle step or beat) when the PWM frequency is equal to the harmonic of the motor commutation frequency. At the same time, it can also reduce the full throttle step. It is especially suitable for use in Damped light mode, but PWM high-frequency pulsation is not suitable for closed loop. 9. Demag compensation: This function is used to prevent the motor from stopping due to the long demagnetization time after commutation. Typically, the motor stops or carton when the throttle is suddenly stepped up, especially when the engine is running at a low speed. As mentioned earlier, setting the commutation angle usually helps to improve the effect, but reduces the efficiency. In general, the higher the compensation parameter setting, the better the protection. However, if the demagnetization compensation value is set too high, the maximum power will also be reduced to a certain extent. 10. Rotation direction: Can be used to set the motor to rotate backwards. 11. (Input pwm polarity) Input PWM polarity settings: can be used to reverse throttle performance. This function can be used to adjust the receiver when it provides negative PWM. When input with PPM, this item must be set to a positive pole.
