Product Usage Instructions

1. Cooling Fan Installation (Optional)
   When pairing the ESC with a 550 motor, it is recommended to install the matching cooling fan. The cooling fan can be powered by the receiver.

2. Receiver Wiring
   Insert the throttle cable of the ESC into the throttle channel of the receiver. Do not supply any other power source to the receiver as the red wire of the throttle cable outputs 6V/7.4V voltage to the receiver and steering servo. If an external power supply is needed, unpin the red wire from the receiver plug, insulate, and secure the plug pin outside of the receiver plug.

3. Battery Wiring
   Ensure proper polarity when connecting the battery. Positive (+) should connect to positive (+), and negative (-) should connect to negative (-). Applying reverse polarity will result in the ESC not functioning.

4. ESC Setup Set the Throttle Range – ESC Calibration – Radio Setup
   To set the throttle range and calibrate the ESC, follow these steps:

5. Press and hold the SET button.

6. Press the ON/OFF button.

7. Release the SET button once the LED flashes.

Make sure to set parameters on the transmitter’s throttle channel accordingly.

FAQ

Q: What should I do if my ESC is not functioning after connecting the battery?

• Always disconnect the batteries when your vehicle is not in use. The ESC will continue to drain current if it is connected to batteries (even if the ESC is turned off). Extended battery connection (Even when off) will cause batteries to completely discharge and result in damage to batteries or ESC. This WILL NOT be covered under warranty.

Features

• Apply FOC(Field Oriented Control) driving mode to the power system of rock crawler. The low speed torque Is very strong, it is better than ordinary censored brushless power system or even better than the brushed power system.
• The chip-type magnetic encoder inside the motor guarantees consistency between three phases’ signals and always outputs the pure and precise signals indicating the rotor position.
• The waterproof and dust-proof design (*IP67 standards) allows the AXE brushless power system to be used in all weather & track conditions without any issue of damage caused to the system from water or dust. Damage to the vehicle caused by water, mud, or conditions should be monitored closely when running in muddy, wet, or adverse conditions.
• Intelligent torque output & speed closed-loop control for easy control, and consistent motor RPM under all loads.
• The adjustable drag brake & drag brake rate control with the maximum drag brake of up to 200% (that’s nearly twice the drag brake of standard brushless power systems) can provide unprecedented parking capacity on slopes, with no jerky stops.
• The innovative built-in Bluetooth connectivity allows users to read ESC data or update ESC firmware via a smart phone (installed with the HW LINK app).
• Multiple protections: low-voltage cutoff, thermal, fail safe (throttle signal loss), motor lock-up, and battery reversal.
• It supports dual operation mode, not only classic “Forward and Reverse (rock crawler)” mode, but also “Forward/Reverse with brake (normal)” mode.

Specifications

Connections

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.

1. Cooling Fan Installation (Optional)
   When pairing the ESC with a 550 motor, we recommend installing the matching cooling fan. The cooling fan can be powered by the receiver.

2. Motor Wiring

3. 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. Next, connect the sensor cable of the esc and motor according to the arrow mark on the sensor connector.

4. Note: AXE R2 esc only supports AXE R2 series motors and does not support the use with other types of motors.

5. Please make sure that the sensor connector of esc and motor is connected according to the arrow direction and tightened. Improper use may damage the internal structure of the sensor connector or cause water ingress, which may lead to abnormal operation.

6. If the motor direction is reversed, change the parameter on item 5 “Motor rotation” to achieve the correct setting.

7. Receiver Wiring
   Insert the throttle cable of the ESC into the throttle channel of receiver. Because the red wire of throttle cable output 6V/7.4V voltage to receiver and steering servo, do not supply any other power source to the receiver, otherwise the ESC may be damaged. If an external power supply is needed, unpin the red wire from the receiver plug, insulate and secure the plug pin out side of the receiver plug.

8. Battery Wiring
   Proper polarity is essential. Please ensure positive (+) connects to positive (+), and negative (-) connects to negative (-) when plugging in the battery! When reverse polarity is applied to the ESC from the battery, it will not function.

ESC Setup

Set the Throttle Range – ESC Calibration – Radio Setup
In order to make the ESC match the throttle range, you must calibrate it when you begin to use a new ESC. If you install a new radio system, or make changes to your throttle/brake values in your transmitter, you must redo the ESC Calibration Process. Failure to calibrate the ESC to your radio system will result in the ESC not working correctly. We strongly recommend activating the “Fail Safe” function of the radio system and set it (F/S) to “Output 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. About setting the throttle range, please follow the following steps：

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). You don’t need to do this step if the transmitter’s settings are default!

2. Start with transmitter on and the ESC turned off but connected to a battery. Holding the SET button and press the ON/OFF button to 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.
   Note: Beeps from the motor may be low sometimes, and you check the LED status instead.

3. Set the neutral point, the full throttle endpoint and the full brake endpoint.

4. Leave the throttle trigger at the neutral position, press the SET button, the RED LED dies out and the GREEN LED flashes 1 time and the motor beeps 1 time to accept the neutral position.

5. Pull the throttle trigger to the full throttle position, press the SET button, the GREEN LED blinks 2 times and the motor beeps 2 times to accept the full throttle endpoint.

6. Push the throttle trigger to the full brake position, press the SET button, the GREEN LED blinks 3 times and the motor beeps 3 times to accept the full brake endpoint.

7. The motor can be started 3 seconds after the ESC/Radio calibration is complete.

Power On/Off & Warning Tones

1. Power ON/OFF:
   (Start with the ESC turned off), press the ON/OFF button to turn on the ESC;
   (start with the ESC turned on) press and hold the ON/OFF button to turn off the ESC.

2. Warning Tones:
   Turn on the ESC in the normal way (that is to turn it on without holding the SET button); the motor will beep the number of LiPo cells you have plugged in.
   For example, 3 beeps indicate a 3S LiPo.

Programmable Items

Note: those black-and-white options are default values.

1. Running Mode

2. Option 1: Forward and Reverse
   This mode is often used by special vehicles (rock crawler). It adopts the “SINGLE-CLICK” method. The vehicle will reverse immediately when you push the throttle trigger forward.

3. 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 forward (away from you) (1st push). If the motor stops when you release the throttle trigger and then re-push the trigger (2nd push), the vehicle will reverse. If the motor does not stop, then your vehicle won’t reverse but still brake, you need to push the throttle trigger one more time. This method is for preventing vehicle from being accidentally reversed.

4. RPM/Throttle Matching
   About this function, the ESC will automatically adjust the motor torque when the load of the vehicle changes. You can adjust the ability of the vehicle to maintain speed when encountering resistance through the options, the higher this value is set, the stronger the ability to maintain speed(the greater the torque increased), which means that the vehicle speed changes less with resistance. If this value is set to “Disabled”, it is similar to normal brushed or brushless power system, the ESC will not automatically adjust the motor torque when the load of the vehicle changes.

5. Cutoff Voltage
   Low Voltage Cutoff for LiPo Protection. This item is mainly for preventing the LiPo pack from over-discharge. If the low-voltage cutoff protection is enabled, the ESC will monitor the battery voltage all the time and gradually reduce the output to 50% (in 3 seconds) and cut it off about 30 seconds later when the voltage goes below the cutoff threshold. The Red LED will flash a single flash that repeats (☆-, ☆-, ☆-….) when the ESC enters the low-voltage cutoff protection. The ESC will not cut off the power when the voltage is low if the low-voltage cutoff  protection is disabled. We don’t recommend setting the “Cutoff Voltage” to “Disabled” when using a LiPo pack, otherwise, the battery will be damaged due to over-discharge.

6. NiMH – For a NiMH pack, we recommend setting this item to “Disabled”.

7. Voltage – The specific voltage values correspond to “Low/Intermediate/high” are 3.0V/3.2V/3.4V per cell. Please note, due to a number of variables you may not see exactly these same voltage values.

8. BEC Voltage
   BEC voltage supports 6.0V/7.4V adjustable, generally 6.0V is applicable to common steering servo， if high voltage steering servo is used, it can be set to 7.4V. Please refer to the steering gear voltage identification for specific setting voltage.
   Note:

9. Do not set the BEC voltage above the maximum operating voltage of the servo, as this may damage the servo or even the ESC.

10. Due to the characteristics of the BEC circuit, there is a voltage difference between the BEC output voltage and the input voltage, when the BEC voltage is set to 7.4V and 2S Lipo is used, the BEC cannot stably output 7.4V（will decrease as the battery voltage decreases） .Therefore, it is recommended to use 7.4V BEC when matching with 3S Lipo.

11. Motor Rotation
    This feature allows the changing of the motor’s forward direction. To check, look at the motor with the shaft facing you. If the motor spins counter clockwise if this item is set to CCW; the motor spins clockwise if set to CW. The drive train of your chassis will determine what direction motor you should use. Some vehicles use normal or CCW rotation, other vehicles use CW or backwards rotation motors.

12. Max. Forward Force
    It’s the force when throttle trigger is at the full throttle position. It’s adjustable among 25%, 37.5%, 50%, 62.5%, 75%, 87.5% and 100% (by default). You can lower down the value for better driving feel/control when you drive a crawler (simulation model) over difficult terrains (and don’t have any requirement against the maximum speed).

13. Punch
    You can choose the punch from level 1 (very soft) to level 15 (very aggressive). This feature is very useful for preventing tires from slipping during the starting-up process. In addition, very high levels 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, and you need to reduce the punch or reduce the pinion gear size.

14. Neutral Range
    As not all transmitters have the same stability at “neutral position”, please adjust this parameter as per your preference. You can adjust to a bigger value when this happens. The neutral range is the “dead zone” or “dead band” of the throttle/brakes. If you notice inconsistent drag brakes, you would increase your neutral range value.

15. RPM Decrease Rate

16. This refers to the speed of rpm change when reducing the throttle (from high to low throttle)，the higher the value, the faster the change. If you want to achieve the experience of natural sliding when reducing the throttle like normal brushless power, this value needs to be set to a low level.

17. Note: This parameter is only valid when “RPM/Throttle Matching” is set to Disabled.

18. Max. Reverse Force
    The reverse force of the value will determine its speed. For the safety of your vehicle, we recommend using a low amount.

19. Max. Brake Force
    This ESC provides proportional braking function, the braking effect is decided by the position of the throttle trigger. It sets the maximum brake force when the throttle trigger is at the full brake position. Large amount will shorten the braking time but it may damage your pinion and spur gear. Please set the appropriate value according to the vehicle’s condition.

20. Drag Brake Force
    It is the braking power produced when the throttle is at the neutral position. (Attention! Drag brake will consume more power and heat will be increased, apply it cautiously.). Higher drag brake means stronger hold or hill brakes.

21. Smart Drag Brake Rate
    When this parameter is set to Enabled, the esc will detect the speed of the motor during running, if the speed is higher, the longer it takes to reach the set value of the drag brake rate (item 14), that is, the slower the drag brake is applied. This helps to prevent overturning or damage to the transmission system due to excessive braking when the vehicle speed is too high. When this parameter is set to Disabled, there is no additional auxiliary processing for the drag brake rate.

22. Drag Brake Rate
    It’s the rate at which the drag brake increases to the preset value. This feature slows down how rapidly the ESC applies brakes. Lower values are slower and prevent sudden stops or jerky stopping movements. You can choose the drag brake rate from level 1 (very soft) to level 15 (very aggressive).

23. Turbo Timing
    This item is adjustable from 0 degree to 10 degrees, the corresponding turbo timing (you set) will initiate at full throttle. It’s usually activated on long straightaway and makes the motor unleash its maximum potential. Turbo timing adds “RPM” at full throttle.

24. Turbo Delay
    When “TURBO DELAY” is set to “INSTANT”, the Turbo Timing will be activated when throttle trigger is moved to the full throttle position. When other value is applied, you will need to hold the throttle trigger at the full throttle position (as you set) till the Turbo Timing initiates.
