Traxxas VXL-3s ESC

Traxxas ESC Programming

Traxxas RC vehicles come with an Electronic Speed Control (ESC) that allows you to change the driving modes and battery type to fit your driving needs. This Traxxas ESC Programming guide will help you learn how to set up and program your Traxxas models. The programming procedures are the same for XL-5 and VXL-3 Electronic Speed Control.

ESC Programming SetupTraxxas ESC Program Setup

Before you attempt to program your ESC, “It” is always a good idea to read the entire process first. When you are programming the ESC and don’t get the proper results, unplug the battery and wait a few seconds, then plug the battery back in and start the procedure over from the beginning.

Electronic speed controls come equipped with built-in Low Voltage Detection systems. The Low-Voltage Detection system constantly monitors the battery voltage. “If” the battery voltage begins to drop to the minimum recommended discharge voltage threshold for LiPo battery packs, the electronic speed control will limit the power output to 50% throttle. “If” the battery voltage starts to attempt to fall below the minimum threshold, the speed control will shut down all motor output completely.

The LED on the speed control will blink red, indicating a low voltage shutdown has occurred. “If” the low voltage shutdown triggers, you will not be able to turn off the ESC from the power button. Your electronic speed control will stay in this mode until the battery is unplugged. Once a fully charged battery is connected, the Electronic speed control is ready for use again.

Your model includes a Power Cell NiMH battery. The electronic speed control’s Low Voltage Detection has been disabled for best performance with this NiMH battery. The ESC LED will be red for NiMH battery and green for LiPo battery setup. Your electronic speed control’s LED will glow red when it is turned on, indicating Low Voltage Detection is disabled. Be certain to activate Low Voltage Detection if you install LiPo batteries in your model. Never use LiPo batteries while Low Voltage Detection is disabled.

Verify that The Low Voltage Detection is DISABLED:

1. Connect a fully charged battery pack to the electronic speed control.

2. Turn on the transmitter, leaving the throttle at the neutral position.

3. Press and release the Set button to turn the speed control on. If the LED is solid red, then the Low Voltage Detection system is DISABLED and not ready for LiPo batteries. If the LED is solid green, then the Low Voltage Detection system is ACTIVATED and ready for LiPo battery use.

To Activate Low Voltage Detection For LiPo Battery:Traxxas ESC Low Voltage on

1. Make sure the LED on the speed control is on and red.

2. Press and hold the ESC Set button for ten seconds.

The LED will turn off and then light green. A “rising” musical tone will be emitted from the motor on brushless equipped models. On Brushed models equipped with the XL-5, EVX-2, and XL-2.5 will beep twice.

3. The low Voltage Detection system is now ACTIVATED.

To disable Low Voltage Detection For NiMH Battery:

1. Make sure the LED on the speed control is on and green.

2. Press and hold the ESC Set button for ten seconds.

The LED will turn off and then light red. A “falling” musical tone will be emitted from the motor on brushless models. On Brushed models equipped with the XL-5, EVX-2, and XL-2.5 will beep three times.

3. The low Voltage Detection system is now DISABLED.

 

ESC Profile Selection

The electronic speed control features three profile modes, profile 1, profile 2 and profile 3. Traxxas has factory set the speed control to Profile #1, which provides 100% forward, brakes, and reverse. Profile #2 allows you To disable reverse or Profile #3 to allow 50% forward and 50% reverse.

Follow the steps below to change the profile modes. Your electronic speed control should be connected to the receiver and a fully charged battery, and the transmitter should be adjusted as described previously. The profiles are selected by entering the programming mode.

Selecting Profile Modes

Sport Mode – Profile #1: 100% Forward, 100% Brakes, 100% Reverse

1. Connect a fully charged battery to the ESC and turn on your transmitter.

2. With the ESC off, press and hold the Set button until the LED turns solid green, then solid red and then it begins blinking red, this indicates the Profile numbers.

3. “If” the LED blinks red once, release the Set button.

4. The LED will blink and then turn solid green, Low Voltage Detection system Active or red Low Voltage Detection system Disabled. The model is now set to Sports Mode and ready to drive.

Race Mode – Profile #2: 100% Forward, 100% Brakes, No Reverse

1. Connect a fully charged battery to the speed control and turn on your transmitter.

2. With the ESC off, press and hold the Set button until the LED turns solid green, then solid red and then it begins blinking red, which indicates the Profile numbers

3. “If” the LED blinks red twice, release the Set button.

4. The LED will blink and then turn solid green to indicate Low Voltage Detection is Active or red to indicate Low Voltage Detection is Disabled. The model is now set in Race Mode and is ready to drive.

Training Mode – Profile #3: 50% Forward, 100% Brakes, 50% Reverse

1. Connect a fully charged battery to the ESC and turn on your transmitter.

2. With the ESC off, press and hold the Set button until the LED turns solid green, then solid red and then it begins blinking red to indicate profile numbers.

3. “If” the LED blinks red twice, release the set button.

4. The LED will blink and then turn solid green to indicate Low Voltage Detection is Active or Red to indicate Low Voltage Detection is Disabled. The model is now set to training mode and ready to drive. Training mode makes it easy to pass the controller off to a beginner.

Fast Blinking Red: Thermal Shutdown Protection

“If” the motor has lower than normal power and the speed control is hot, the electronic speed control entered stage 1 thermal shutdown protection to guard against overheating caused by excessive current flow. If the motor has no power and the speed control is very hot, the electronic speed control entered stage 2 thermal shutdown protection and has automatically shut down. When this happens, you need to let the speed control cool down. Make sure your model is properly geared for the conditions by referring to the gearing chart in your model’s manual.

Slow Blinking Red: Low Voltage Protection

“If” the Low Voltage Detection system is on and the ESC LED blinks red slowly, Your electronic speed control has entered Low Voltage protection. “If” the battery voltage begins to drop to the minimum recommended discharge voltage threshold for LiPo batteries, the speed control will limit the power output to 50% throttle. “If” the battery voltage starts to fall below the minimum threshold, the speed control will shut down all motor output completely. The LED on the speed control will slowly blink red, indicating a low voltage shutdown. Your electronic speed control will stay in this mode until the battery is unplugged and fully disconnected.

Blinks Red then Green repeating: Over Voltage Protection

If the motor has no power, the speed control has entered Over Voltage Protection. If using a battery with too high voltage, the electronic speed control will go into a fail-safe mode.

Blinking Green:

“If” the LED is blinking green, Your electronic speed control is indicating that the transmitter Throttle Trim is incorrectly set. If the Multi-Function knob is set to throttle trim, then adjust the Throttle Trim to the middle “0” setting.

ESC Programming Thoughts

The programming of the ESC is easy to do yourself. “If” you follow this guide, you will be able to set up and program your model’s ESC in no time and with ease every time. “I” hope this article has helped you with your ESC setup and programming needs.
