Product Parameter

Drawing Dimension

Function Introduce* Operation Mode: Motor rotation direction setup Forward / Forward & Backward Mode Optional
* Motor Timing: Extremely Low/ Low/Medium/High/Extremely High
   Normally, Low Timing can fit for major motors. Due to the great difference in motor structure, please try any Motor Timing to obtain satisfactory      driving effect. In order to increase rotation speed, can set to High Timing mode, but the motor efficiency will be reduced and the heating will be faster.

* Starting Acceleration: Super Soft launch/Soft/Accelerate As set to high acceleration ,the relationship between the rotate speed of motor and throttle is relatively linear. but high working current, Easy to cause current protection. Soft start and Super soft start both have low acceleration of rotate speed , even instantly throttle stick is pushed to the maximum position, motor from static to full speed need for a delay while.  

* Low Voltage Protection Value: No protect/3.0V/3.1V/3.2V/3.3V/3.4VWhen the Battery Type is Lipo, ESC automatically calculates the number of lithium battery cells.
For example, Using 12 cells of lithium batteries, Cut-off voltage set to 3.0V/cell, the Low Voltage Protection Threshold: 3.0*12=36.0V
When the Battery Type is Nimh/Nicd, No need Low Voltage Protection.

* Motor Direction: Forward and Backward rotationMost case, Motor forward and backward is generally achieved by change any two motor wires. When the motor wire has been soldered directly to the ESC, the motor can be changed direction by changing the setting value on the ESC.

* Frequency Type: High/Low/snub If choose High frequency to Multipole motor and High RPM motor,the Motor will operate faster and smoothly, but the switch lost of ESC MOSFET will be great and MOSFET heat faster.
With the excessively larger current, the MOSFET easy to burn out. So, we recommend to select low driving frequency as ESC work at high current .

* Forward Speed Percentage: 20%/40%/60%/60%/100%  This setting limits the maximum forward speed.

* Backward Speed Percentage: 20%/40%/60%/60%/100%  This setting can limit the maximum backward speed

Factory SettingMinimum/Medium/Maximum Throttle Value, 1000/1500/2000 is factory settings.
This value will change with the value of the remote controller when calibrate the setting of throttle .

ESC/Motor Temperature Protection, when the temperature of ESC/Motor exceed the SET Value, ESC will reduce the speed by 50% and enter into protect condition. If turn off this function,ESC will keep working according to the throttle indication.

Starting Strength
The torque setting during startup. When the setting value is large, the startup torque is large and the initial speed is large. On the contrary, the startup torque is small and the speed is low.

Motor shutdown and locked.
When throttle return to nature and setup turnoff, the motor will follow the inertia and continue to rotate. When setup open, the motor will brake and stop rotating immediately.

Demagnetization compensation,
When motor accelerate faster and working on large current will cause the coils of motor of demagnetization for an extended period and rotation is not smooth. Meanwhile, it is necessary to turn off power of coil for a moment and wait for coils to demagnetize. This method will reduce the power of motor. 

RC Throttle Stroke Setting

1.When using Gun Type Remote Controller (The ESC Operation Mode set to Forward/Backward Type), The throttle stroke Calibration Method is as follows:
Turn On the controller and push to Maximum throttle value ,then power on the ESC and will hear the sound of motor like "DI DI' sound .
When continuously hear the sound of motor "DI DI " during four times , push the throttle rocker to minimum value. Then will hear the sound of"DI DI DI"on the motor, then loosen the throttle to nature and heard a special confirm sounds, it indicates the Calibration set up well and save already.

2.When using plate-type controller (The ESC operation mode set to Forward Type), The throttle stroke Calibration Method is as follows:
Turn on the controller and push to Maximum throttle value, then power on the ESC and wait for two seconds. Then  will hear the sound of motor like "DI DI"sound, push the throttle rocker to minimum value and hearing the motor making special confirm sound, it indicates the travel of throttle set up well and save already.

Remark: In order to match the ESC to the travel of your controller throttle, Please reset the travel of throttle when using this ESC for the first time or change to use another controller.
