4. makes a long beep sound System detects battery voltage and makes several short beep sounds which denotes the number of battery cells when self test is finished gt 123 tone should be emitted ready for start Setting Throttle Range Throttle range should be setup when a new transmitter is being used Manual of Sensorless Brushless Motor Speed Controller SET KEY is used Switch off the ESC gt Switch on the transmitter Press and hold the SET KEY gt Switch on the ESC gt Push the throttle stick to the top point of forward within two seconds gt Wait for one second System detects the Max throttle signal and makes two beep sounds which denotes that Max throttle has been confirmed and saved gt Pull the throttle stick to the top point of backward System detects the Min throttle signal makes two beep sounds which denotes that Min throttle has been confirmed and saved Release the SET KEY Setting is finished The LED Status 1 The green LED lights when the car go forward the red LED lights when the car is backward both the red and green LED light when the car is braking 2 when the car stops red LED and green LED don t light 3 both the red and green LED flash when the voltage is low or over or the ESC is over heat Protection A Low voltage protection When power voltage is lower than the cutoff threshold ESC will cut off output power B Thr
5. ottle signal lose protection The ESC will cut off the motor if throttle signal lost for 0 5 second C Overheat protection output power will be reduce to cool down if temperature of the board of CPU gets to 100 C and the output power will raise after temperature gets low D Self check ESC will start self test when power on if self test fail ESC will continuously emit 20 short beep tones Configurable Parameter with LED Program Card Program Card not included 1 Cut Off Voltage Low voltage Protection threshold User can set proper cutoff voltage according to cell quantity in range of 00 0 49 9V the default is 00 0V Note System will detect battery cells and calculate proper threshold automatically if this setting is 00 0V protection threshold for each Li XX cell is 2 8V For example if the battery pack is 3 cells Li xx cutoff voltage will be 2 8V 3 8 4V 2 Start Power Percent Start Force to set the Percent of output power when the car start in range of 00 29 default is 00 Under default setting output power is decided automatically by system according to throttle stick position 3 Advance Timing low middle high and highest Default is middle Low advance timing is recommended for high inductance and low KV motors High advance timing is recommended for low inductance and high KV motors 4 Run Mode One Two Two2 Default is Two2 One the car can go forward only and brake continuously if push the throttle

7. stick to backward zone Two Bi directional mode the car go forward when the throttle stick is located at the forward zone when the throttle stick is located at the backward zone the car will go backward the brake will occur when direction change Two2 Conditional Bi directional mode the car go backward only when car is stop and throttle stick is pushed from neutral zone to backward zone When car is running forward push throttle stick to backward zone car will keep brake until it stops the throttle stick return the neutral zone and push the throttle stick to the backward zone then the car will go backward 5 Brake Force 50 75 100 Default is 100 The ESC provides proportional brake function The brake force is related to the position of the throttle stick It refers to the maximum brake force when the throttle stick is pushed to the top point of the backward zone 6 Drag Brake Force 0 5 10 15 20 Default is 0 When the throttle stick is located at the neutral zone the ESC provides a slight brake force 7 Neutral Range 6 8 10 Default is 8 Within this zone the motor will be turned off 8 Initial Brake Force 5 10 20 30 Default is 5 It refers to the brake force when the throttle stick is located at the initial position of the backward zone 9 Reverse Force 25 50 75 100 Default is 25 It refers to the maximum force when car run in reverse direction Programming the ESC with key Manual of Senso
