Sine Wave Start-up: Supports smooth, sensorless sine wave start-up. Supports firmware upgrades and parameter settings via PC software or web-based tuning tools. This product features a compact layout and lightweight design, making it particularly suitable for installation in drones with limited arm space. The ESC is equipped with high-precision current and temperature sensors, enabling real-time transmission of operating data via the serial TX pin; Signal cables are made of twisted silicone rubber, effectively reducing signal interference caused by copper wire transmission and further enhancing flight stability; Equipped with an aluminum alloy heat sink for efficient heat dissipation, ensuring stable operation over extended periods; Wiring diagram: To prevent short circuits and electrical leaks, please ensure that all connections are properly insulated. Programmable parameters: Reverse Rotation: Changes the motor’s default rotation direction; Complementary PWM: When enabled, the ESC actively slows the motor when the throttle is reduced, rather than allowing it to coast freely. This significantly improves control response; Variable PWM: When enabled, the ESC dynamically adjusts the PWM frequency based on the motor’s actual speed. This provides smoother operation at low speeds and optimizes efficiency at high speeds; Bi-directional (Fwd/Rev): Allows the motor to rotate both forward and backward. The motor stops at throttle neutral; pushing the throttle causes forward rotation, and pulling the throttle causes reverse rotation. Suitable for 3D aircraft, car models, or RC cars with a “reverse flip” (backflip) function; Stuck Rotor Protection: When the ESC detects that the motor is jammed by a foreign object and cannot rotate, it automatically cuts off the current to prevent burning out the motor or the ESC board; Brake On Stop: When the throttle is reduced to 0, braking force is applied to the motor to bring it to a rapid, complete stop. This is commonly used in gliders with folding propellers to prevent the propeller blades from continuing to rotate and creating drag during unpowered gliding; Stall Protection: Provides a protection mechanism to attempt recovery or shutdown when high load causes the motor and ESC to lose synchronization (desynchronization); Sinusoidal Startup: Uses a sinusoidal algorithm to drive the motor during startup, resulting in a smoother start-up process and reducing startup noise and vibration; 30 ms Telemetry: Sends ESC status data (such as RPM, current, voltage, and temperature) to the flight controller via the telemetry port every 30 milliseconds; Use Hall Sensors: If using a “sensor-equipped brushless motor” with Hall sensors, selecting this option provides extremely precise low-speed control (commonly used in rock crawlers, etc.); Timing Advance: The motor timing advance can be set to Auto or 1–31°. A medium timing advance value is typically suitable for most motors, but if the motor runs unevenly, try adjusting the timing advance. For some high-sensitivity motors, the commutation demagnetization time is relatively long, especially during low-speed operation. In such cases, the motor may stall or run unevenly when throttle is rapidly increased. Increasing the timing advance helps mitigate this issue, as a higher advance angle allows for a longer commutation demagnetization time; Motor KV: The KV value represents the increase in no-load speed per 1V increase in voltage. The KV value is generally set near the motor’s rated KV value to achieve optimal performance; Motor Poles: Refers to the number of magnetic poles (magnets) inside the motor’s rotor. The ESC must know the correct number of poles to calculate the motor’s actual speed; an incorrect setting will result in abnormal telemetry speed readings; Startup Power: Used to set the initial torque during motor startup. Setting this too low may cause the motor to fail to start or exhibit abnormal vibration, while setting it too high may result in an overly aggressive startup, which in severe cases could cause propeller blades to fracture or components to burn out; PWM Frequency: The frequency at which the ESC controls the motor pulses. Higher frequencies reduce high-frequency noise and provide smoother operation, but the ESC is more prone to overheating (this parameter generally does not need to be adjusted); Beep Volume: The volume of the alert sound emitted when the ESC powers on or triggers an alarm. Note: The ESC itself does not have a speaker; it generates sound by inducing micro-vibrations in the motor windings via high-frequency current (this parameter does not require adjustment); Sine Startup Range: Determines the speed range within which Sinusoidal Startup remains active after takeoff; beyond this range, the system switches back to conventional square wave/trapezoidal wave drive; Sine Mode Power: The amount of power supplied to the motor during the Sinusoidal Startup phase; Running Brake Level: The amount of braking force actively applied by the ESC when the throttle is reduced (but not fully released to 0) during flight or driving; Notes: Battery Management: Ensure the battery is properly balanced to prevent overvoltage or over-discharge in any single cell; Never reverse the positive and negative terminals Correct Power-On Sequence Wait for the self-test to complete: After powering on, wait for the ESC to complete the throttle signal detection and initialization self-test (indicated by a normal beep). Only unlock the flight controller after confirming the self-test is normal; never unlock it immediately after powering on; Troubleshooting Unexpected Power Loss Firmware Flashing Warning: Do not flash firmware not compatible with this ESC, as this may cause permanent damage to the ESC; DSHOT Wiring Guidelines: When using the DSHOT signal protocol, it is recommended to retain the ground wire from the ESC’s original twisted-pair signal cable to ensure a reliable signal ground connection and maintain signal stability; Advance Angle Parameter Adjustment Instructions: If the motor experiences abnormal conditions such as rough startup, or if you need to increase the motor’s maximum speed, you may try adjusting the ESC’s advance angle parameter to optimize performance; Operating Limits: Never exceed the ESC’s rated operating current or voltage range to prevent equipment damage due to overloading; Safety Guidelines: Before performing any operations, such as plugging or unplugging cables or connecting wires, ensure the system power is completely turned off to prevent live-wire operations; Manual download link: https://cdn.shopify.com/s/files/1/0011/4039/1996/files/FSESC_1680_G1_V1.0_AM32.pdf?v=1781252968
