User Guide

Throttle Calibration & ESC Programming

Before first use, users must calibrate the throttle range to ensure proper performance. Follow these steps:

Step 1: Motor Wiring

1. Connect the motor to the ESC.
2. Plug the throttle signal cable into the TH channel on the receiver.
3. Connect the UBEC cable to the BATT channel (or any free receiver channel).
4. Power the system using a compatible LiPo battery.

Step 2: Throttle Range Calibration

1. Turn on the transmitter and move the throttle stick to the top position.
2. Ensure the transmitter and receiver are well bound, then connect the ESC to the battery.
3. When the motor emits two short Beep-beep sounds, move the throttle stick to the bottom within 3 seconds.
4. Throttle calibration is completed.

Important: Remove propellers before performing calibration for safety.

Step 3: ESC Programming

1. Turn on the transmitter and move the throttle stick to the top position.
2. Connect the ESC to the battery while ensuring the transmitter and receiver are bound.
3. The motor will beep different tones indicating programming mode.
4. Listen for the corresponding beeps:
   • “Beep-beep” Throttle Calibration
   • “Beep-beep-beep” DEO ON
   • “Beep-beep-beep-beep” DEO OFF
5. Move the throttle stick to the bottom position 3 seconds after hearing the correct beep to complete programming.

Normal Start-up Process & Protections

Start-up Protection

• If the motor fails to start within 2 seconds, the ESC shuts down automatically to prevent damage.
• Users must reset the throttle stick to the bottom position and restart the motor.

Overload Protection

• The ESC will cut off power if the load suddenly increases beyond safe limits.
• Normal operation resumes once the throttle stick is reset to neutral.

Throttle Signal Loss Protection

• If the ESC detects a signal loss exceeding 0.25 seconds, it cuts off output to prevent motor damage.
• Once the signal is restored, the ESC resumes normal operation.

Troubleshooting

This XROTOR Pro 40A ESC is an excellent choice for high-performance drone applications, offering smooth operation, precise control, and multiple safety features to ensure a reliable and stable flight experience.
