Detailed Setup Instructions

Throttle Range Calibration

Throttle calibration is necessary for the ESC to respond accurately to remote control commands. Below is a step-by-step guide in a numbered list format.

• 1. Turn off the controller and check connections: power, motor, receiver.
• 2. Turn on the remote control and set the throttle stick to the maximum position.
• 3. Connect the battery to the controller.
• 4. You will hear two beeps — the ESC has received the maximum power signal.
• 5. Move the throttle to the minimum position — another beep will sound, confirming calibration.
• 6. The controller is ready for operation; if the motor does not respond, repeat the procedure.

Setup via Remote Control

The T-Motor AT-75A supports full programming from the remote: you can change braking parameters, start mode, low voltage thresholds, and other settings without additional equipment.

• 1. Turn on the remote and set the throttle to maximum.
• 2. Connect the battery — after a series of beeps, the ESC will enter programming mode.
• 3. After the beeps, lower the throttle to minimum and select the desired parameters.

Parameter Selection and Change

Below are the available parameters and values, selected by the number of beeps during programming.

• Brake Type: 1 beep — No Brake; 2 beeps — Normal Brake; 3 beeps — Reverse Brake; 4 beeps — Linear Reverse Brake.
• Brake Force: 1 beep — Low; 2 beeps — Medium; 3 beeps — High.
• Low Voltage Protection Mode: 1 beep — Soft Cut-off; 2 beeps — Hard Cut-off.
• Battery Cell Count: 1 beep — Automatic Mode; 2 — 2 Cells; 3 — 3 Cells; 4 — 4 Cells; 5 — 5 Cells; 6 — 6 Cells.
• Low Voltage Threshold: 1 beep — Disabled; 2 beeps — Low Threshold (2.8V); 3 beeps — Medium Threshold (3.0V); 4 beeps — High Threshold (3.4V).
• Start Mode: 1 beep — Normal Start; 2 beeps — Soft Start; 3 beeps — Ultra-Soft Start.
• Timing Advance (Timing): 1 beep — Low 5°; 2 beeps — Medium 15°; 3 beeps — High 25°.

Exiting Programming Mode

• 1. After configuration, the ESC will emit a special beep indicating completion.
• 2. Move the throttle stick to the minimum position within 3 seconds.
• 3. The ESC will exit programming mode, and the motor will emit several short beeps, indicating readiness for operation.

Protection Functions

• Start-up Protection: automatic restart attempts in case of unstable RPM.
• Signal Loss Protection: power cut-off if no signal for more than 0.25s to prevent accidents.
• Motor Lock-up Protection: automatic shutdown in case of physical obstruction to prevent damage.
• Overheat Protection: at >120°C, power is reduced to 60% for cooling.
• Low Voltage Protection: power reduction when thresholds are reached to protect the battery.

This controller is ideal for users who value stability, safety, and fine-tuning capabilities. It is compatible with a wide range of batteries and ensures reliable operation in demanding conditions.
