05. Connect ESC

Connect ESC

Note: This is an extremely powerful brushless motor system. For your safety and the safety of those around you, we strongly recommend removing your pinion gear before performing calibration and programming functions with this system, and keeping wheels in the air when you turn on the ESC.

Please wire correctly according to wiring instructions and wiring diagram.

  1. Motor Wiring
    The sensored motor wiring is a little different from the sensorless motor wiring; please make sure that you will strictly follow the introductions below.
    A. Sensored Brushless Motor Wiring
    There is strict wiring order from the ESC to the motor, the three A/B/C ESC wires must connect to the three A/B/C motor wires correspondingly and then connect the ESC sensor port
    and the motor sensor port with the stock 6-pin sensor cable.
    Note 1: If you don’t plug the sensor cable in, your ESC will still work in sensorless mode. It is like the ESC connects to sensorless brushless motor.
    B. Sensorless Brushless Motor Wiring
    There is no polarity on the A/B/C wires between ESC and motor, so do not worry about how you connect them initially. You may find it necessary to swap two wires if the motor runs in
    reverse.
  2. Receiver Wiring
    Plug the throttle control cable (also called Rx cable) on the ESC into the throttle (TH) channel on receiver. So please do not supply power to the receiver. Otherwise, your ESC may be
    damaged.
  3. Battery Wiring
    Connect the battery when the ESC is power off. Make sure positive (+) of ESC connects to positive (+) of battery, and negative (-) of ESC connects to negative (-) of battery when you
    plug in your battery! Then turn on the ESC to run it.

06. ESC Setup

1. Set throttle range

You must reset throttle range when you begin to use a new ESC, or the transmitter changes the parameters such as the TRIM, D/R, EPA and other parameters, otherwise the ESC cannot work properly.
We strongly recommend to activate the “Fail Safe” function of the transmitter and set no signal protection for throttle channel of transmitter (F/S) to “OFF” or set its value to the “Neutral
Position” to ensure the motor can be stopped when there is no signal received from the transmitter. The throttle calibration steps is as follows:

Set throttle range

  1. Turn on the transmitter, set parameters on the throttle channel like “D/R”, “EPA” and “ATL” to 100% (for transmitter without LCD, please turn the knob to the maximum) and the
    throttle “TRIM” to 0 (for transmitter without LCD, please turn the corresponding knob to the neutral position).
  2. Turn off the ESC. Hold the SET button and turn on the ESC, the RED LED on the ESC starts to flash (the motor beeps at the same time), and then release the SET button immediately. (The
    ESC will enter the programming mode if the SET button is not released in 3 seconds, then you need to restart from step 1.)

Note : Beeps from the motor may be low sometimes, and you can check the LED status instead.

3. Set the neutral point, the end position of forward and the end position of backward.

1) Leave the throttle trigger at the neutral position, press the SET button, the RED LED dies out and the GREEN LED flashes once and the motor beeps 1 time to store the neutral position.
2) Pull the throttle trigger to the end position of forward, press the SET button, the GREEN LED flashes twice and the motor beeps 2 times to store the end position of forward.
3) Push the throttle trigger to the end position of backward, press the SET button, the GREEN LED flashes 3 times and the motor beeps 3 times to store the end position of backward.

Note:

  • The end position of forward: Pull the trigger to the maxim um throttle position if it is pistol-style transmitter . Push the throttle to the top if it is board-style transmitter .
  • The end position of backward: Push the trigger to the maximum brake position if it is pistol-style transmitter. Pull the throttle to the bottom if it is board-style transmit ter.

4. The motor can work normally after the throttle range calibration is complete.

2. Programmable Items

Those “black background and white text” options are the factory default settings.

Programmable Items

  1. Running Mode
    Option 1: Forward with Brake
    The vehicle can go forward and brake but cannot reverse in this mode. This mode is usually for racing.
    Option 2: Forward/Reverse with Brake
    This mode provides the braking function, it’s usually for training. “Forward/Reverse with Brake” mode adopted the “DOUBLE-CLICK” method, that is your vehicle only brakes (won’t reverse)
    when the 1st time you push the throttle trigger from neutral zone to backward zone. If the motor stops when the throttle trigger quickly return to the neutral zone and then re-push the
    trigger to backward zone, the vehicle will reverse. If the motor does not stop, then your vehicle won’t reverse but brake, you need to return the throttle trigger to the neutral zone and push
    it to backward zone again. The vehicle only reverses after the motor stops. This method is for preventing vehicle from being accidentally reversed.
    Option 3: Forward/Reverse
    This mode used the “SINGLE-CLICK” method to make the car go backward. When you move the throttle trigger from neutral zone to backward zone, the car will go backward immediately.
  2. Drag Brake Force
    Drag brake is the braking power produced when releasing the throttle trigger to neutral zone. This is to simulate the resistance applied by carbon brush of the brush motor to rotator of
    motor while coasting.(Attention! Drag brake will consume much power, so please apply it cautiously.)
  3. Cutoff Voltage (or Low Voltage Cutoff Threshold)
    The ESC will monitor the battery voltage all the time, on ce the voltage is lower than the threshold value, the ESC will reduce the power to 50% and cutoff the power output in 10
    seconds. When enters into voltage pr otection, the RED LED will single flash that repeats (, , , …….). Please set the “Cutoff Voltage” to “Disabled” if you are using NiMH batteries.
  4. Start Mode / Punch
    You can choose the punch from level 1 (very soft) to level 9 (very aggressive) as per the track, tires gripping, your preference and etc. This feature is very useful for preventing tires from
    slipping in the starting-up process. In addition, “level 7”, “level 8 and “level 9” have strict requirement on battery’s discharge capability. It may affect the starting-up if the battery
    discharges poorly and cannot provide large current in a short time. The car stutters or suddenly loses power in the starting-up process indicating the battery’s discharge capability is not
    good; you need to reduce the punch or increase the FDR (Final Drive Ratio).
  5. Max. Brake Force
    This ESC provides the proportional braking function; the braking effect is determined by the position of the throttle trigger. The max. brake force is produced when the throttle trigger is at the
    brake bottom position. Please select the max. brake force parameter as per your car condition and your preference.
  6. Max. Reverse Force
    Different reverse amount will bring different reversing speed. For the safety of your vehicle, we recommend using a low amount.
  7. Initial Brake Force
    It also called min. brake force. It refers to the brake force applied to the motor at the initial position. It seems like point brake. The default value is equal to the drag brake force, so as to
    form a soft brake effect.
  8. Throttle Neutral Range
    As not all transmitters have the same stability at “neutr al position”, please adjust this parameter as per your preference. You can adjust to a bigger value when this happens.
  9. ESC Thermal Protection
    The output from the ESC will be cut off with the value you have preset. The GREEN LED flashes (, , ) when the ESC temperature reaches to the preset value. The output will not
    resume until the ESC temperature gets down.
    Warning! Please do not disable this function unless you’re in a competition. Otherwise the high temperature may damage your ESC and even your motor.
  10. Motor Thermal Protection
    After enable this function, the output will be automatically closed when the motor temperature reaches the preset value. The green light flashes until the temperature drops to restore the
    output. When the motor is overheated, the green light will flash twice in cycle.
    Warning! Please do not disable this function unless you’re in a competition. Otherwise the high temperature may damage your motor and even your ESC. For non-Hobbywing
    motor, the ESC may get this protection activated too early/late because of the different temperature sensor inside the motor. In this case, please disable this function and
    monitor the motor temperature manually.
  11. Motor Rotation
    It is used to adjust the rotation direction of the motor (in CW or CCW), that is, when the forward throttle is given, and the rotation direction of the motor is reverse, it can be set to the
    opposite direction.
  12. BEC Voltage
    The BEC voltage can be adjusted at 6.0V and 7.4V. The normal steering servo is generally set at 6.0V, and the high-voltage steering servo can be set at 7.4v. Select the appropriate voltage
    according to the steering servo used.
  13. RPM Limit
    It is used to set the max. RPM value of the motor. Set corresponding values according to competition rules.
    This parameter has two choices according to different versions of ESC used:
    1. If use Hobbywing’s Standard ESCXR10 Justock G3, then select rpm limit of “Standard” in the table.
    2. If use Hobbywing’s Handout ESCXR10 Justock G3-Handout Spec, then select rpm limit of “Handout” in the table.

3. ESC Programming

1. Programming your ESC with the SET button

Programming your ESC

Note: 

  • For easy recognition, the motor beeps at the same time when the LED flashes.
  • When “N” (the number) is equal to/bigger than 5, we use a long flash to represent “5”. For example, the GREEN LED flashes a long flash (and the motor beeps a long beep at the same time) indicating you are in the 5th programmable item; if the GREEN LED flashes a long flash and a short flash (and the motor beeps a long beep and a short beep at the same time) indicating you are in the 6th programmable item; a long flash and two short flashes ( a long beep and two short beeps at the same time) indicating you’re in the 7th programmable item and so on.

2. Program your ESC with a LCD program box

(For detailed information, please refer to the user manual of the LCD program box.)
You can use LCD program box to set parameters, or connect LCD program box with computer to set parameters (use HOBBYWING USB LINK software). Connect the ESC and LCD program box via a cable with two JR male connectors. Then power on the ESC, the LCD setting box will display the boot interface. Press any key on the LCD program box to set up communication between the LCD program box and the ESC, and displaying “CONNECTING ESC”. After several seconds, the current mode name will be displayed, and the first setting parameter will be displayed after that. Press “ITEM” and “VALUE” button to change the parameters. Press “OK” button to store the parameters to your ES.

3. Program your ESC with a OTA Programmer

Plug the programming cable of OTA Programmer to the programming port of ESC. Then use the mobile phone to install HOBBYWING HW LINK App to set parameters

Connect LCD program box

4. Factory Reset

1) Restore the default values with the SET button Press and hold the SET button for over 3 seconds anytime when the throttle trigger is at the neutral position (except during the ESC calibration and programming) can factory reset your ESC. RED & GREEN LEDs flash simultaneously indicating you have successfully restored all the default values within your ESC. Once you power the ESC off, and then back on, your settings will be back in the default mode.

2) Restore the default values with a multifunction LCD program box After connecting the program box to the ESC, continuously press the “ITEM” button on the program box until you see the “RESTORE DEFAULT” item, and then press “OK” to factory reset your ESC.

3) Restore the default values with a OTA Programmer(Use HW LINK mobile phone App) Connect OTA Programmer to the ESC, enter into [Parameters], click “reset” to factory reset your ESC.

07. Explanations for Different Status LED

  1. The throttle is in neutral zone
    1) In normal Blinky mode (non-rpm limit mode), the red LED flashes rapidly.
    2) In the RPM limit mode, there are two different flashing modes due to two versions of XR10-Justock G3 and XR10-Justock G3 Handout Spec, the details are as follows:
    XR10-Justock G3:
    In RPM limit mode, when RPM limit is 25,000, the red LED long flashes once and the green LED flashes once.
    In RPM limit mode, when RPM limit is 22,500, the red LED long flashes once and the green LED flashes twice.
    In RPM limit mode, when RPM limit is 20,000, the red LED long flashes once and the green LED flashes three times.
    In RPM limit mode, when RPM limit is 17,500, the red LED long flashes once and the green LED flashes four times.
    In RPM limit mode, when RPM limit is 15,000, the red LED long flashes once and the green LED flashes five times.
    In RPM limit mode, when RPM limit is 12,500, the red LED long flashes once and the green LED flashes six times.
    XR10-Justock G3 Handout Spec:
    In RPM limit mode, when RPM limit is 33,500, the green LED long flashes once and the red LED flashes once.
    In RPM limit mode, when RPM limit is 30,000, the green LED long flashes once and the red LED flashes twice.
    In RPM limit mode, when RPM limit is 26,500, the green LED long flashes once and the red LED flashes three times.
    In RPM limit mode, when RPM limit is 23,500, the green LED long flashes once and the red LED flashes four times.
    In RPM limit mode, when RPM limit is 20,000, the green LED long flashes once and the red LED flashes five times.
    In RPM limit mode, when RPM limit is 18,000, the green LED long flashes once and the red LED flashes six times.
  2. The throttle is in non-neutral zone
    1) The RED LED turns on solid when moving forward. Green LED is also on when throttle trigger is at the end position of forward100% throttleon non-speed limit mode).
    2) The RED LED turns on solid when you brake. The GREEN LED will also come on when pushing the throttle trigger to the full brake endpoint and setting the “Max. Brake Force” to 100%.
    3) The RED LED turns on solid when you reverse your vehicle.
  3. LED status when some Protection is Activated:
    1) The RED LED flashes a short, single flash that repeats  indicating the low voltage cutoff protection is activated.
    2) The GREEN LED flashes a short, single flash that repeats  indicating the ESC thermal / overheat protection is activated.
    3) The GREEN LED flashes a short, double flash that repeats  indicating the motor thermal /overheat protection is activated.
    4) The GREEN LED flashes a short, five times flash that repeats) indicating the capacitor thermal /overheat protection is activated.
