MUHIMU: To reduce the risk of fire, bodily injury, and damage to the equipment, read through Instruction Manual before operating ESC and always follow all instructions.

KEEP OUT OF THE REACH OF CHILDREN. Pay attention to the maximum voltagnaruhusiwa:

• KDE-UAS LV Series 7.4V (2S LiPo) – 26.1V (6S LiHV) 26.5V Max.
• KDE-UAS XF Series 7.4V (2S LiPo) – 34.8V (8S LiHV) 35V Max.
• KDE-UAS HVC Series 11.1V (3S LiPo) – 52.2V (12S LiHV) 55V Max.
• If model is not listed, maximum voltage is stated in specifications. Operating outside of the listed voltage voids warranty.
• All KDE Direct ESCs are opto-isolated and do not provide BEC power output for the peripheral equipment and requires 3 to 12V applied to the control lead. Never operate the ESC beyond the specifications stated on hardware.
• Serious injury or property damage can result from misuse.
• Ensure the polarity is correct with the power supply to the ESC power source leads. Reverse polarity may cause fire and serious injury and will immediately damage the ESC beyond warranty coverage.
• Ensure the ESC is installed in a safe location and protected to prevent any exposed connections and solder locations from contacting conductive areas. Always use electronics-grade solder and make sure to use proper soldering techniques and equipment. Poor soldering technique is a common cause of in-flight failure and ESC damage. Ensure all connectors are protected with insulation and heat-shrink to prevent unwanted conduction and shorts.
• Check all connectors for secure connection before flight. Disconnection due to vibration and flight-conditions can result in a dangerous loss of control and potential damage and serious injury.
• Do not disassemble or open the ESC or DMA. Opening of the case or removal of shrink-wrap may cause damage to the internal components, void all warranty claims, and yield unsafe operation.
• Install the ESC in a location with adequate airflow to maintain cool temperatures and achieve the maximum performance rating.
• An electric motor that is connected to the ESC can start unexpectedly and can cause serious injuries. Always remove the propeller and disengage all gearing when working on the system with power applied.
• Do not allow full submersion of the ESC in water. Water can damage the ESC and cause malfunction and failure of the electrical components.
• KDE Direct is not responsible for the use of this Product(s) or for any damages or injuries caused or sustained by its usage. Always observe all laws and instructions regarding the use of this Product(s), and operation of devices using this Product(s).
• This is a high-power, electromechanical device with the potential to be very dangerous – always handle with caution and be aware of proper operation. This product may contain chemicals known to the State of California to cause  cancer and/or birth defects or other reproductive harm. Do not ingest or attempt to ingest this product.
• Disconnect brushless motor from ESC motor leads before programming ESC. An electric motor that is connected to the ESC can start unexpectedly and cause serious injuries or damage.
• Before flight, ensure that all ESCs are operating on the same settings and firmware.
• Extending the ESC power leads is at your own risk and voids the warranty. At low load we recommend you turn off Synchronous Rectification, low load may result in discontinuity with the motor RPM.
• The KDE Direct UAS ESC (Electronic Speed Controller) Series is engineered specifically for multi-rotor applications. Each ESC is factory calibrated and utilizes a proprietary control algorithm to deliver high-speed response and low-latency performance for precise and stable flight.

ESC INSTALLATION AND WIRING

Pay close attention to proper wiring as shown in the diagram above. Ensure the polarity is correct and proper soldering techniques are used when connecting the power source and brushless motor to prevent damaging the ESC.

KALIBRATION YA ESC THROTTLE

The UAS ESC Series is optimized for the KDE Direct UAS Brushless Motor Series and is designed for simple, plug-and-play operation using the default settings. If manual throttle calibration is desired, this option can be selected via the KDE Direct Device Manager Adapter (DMA) programming kit (sold separately). Always remove the propellers before calibrating the ESC. All ESCs are factory-calibrated and utilize a proprietary auto-scaling algorithm that dynamically adjusts to the connected receiver (RX) and/or flight controller.

1. Ensure the ESC control lead is connected to the throttle channel on your receiver (RX) or flight controller, confirming correct orientation of plugs.
2. Turn on the transmitter (TX) and set the throttle-stick position to zero or low (0% throttle signal) to arm the ESC circuitry.
3. Connect the battery or power system to the ESC power source leads. The ESC will remain disarmed until a 0% throttle signal is received. An arming-tone will be heard and the number of LiPo battery cells will be heard as individual tones, followed by additional and final arming tones.
4. If arming tones are not heard, adjust the transmitter throttle end-points (ATV/AFR) values until the arming sequence is heard. Check the operation of the ESC with the receiver (RX) throttle channel for correct direction and reverse if necessary (reverse direction for Futaba systems).
   If the arming throttle signal (0%) is not applied when the power source is first connected to the ESC, short tones will continuously sound after approximately five (5) seconds. To remove this warning tone move the throttle to 0% or disconnect power.
5. Check for proper rotation direction of each ESC/motor combination. To change rotation direction, swap ANY two brushless motor lead connections.

COMPATIBILTY AND OPTIMIZATIONS

New technologies incorporated into the latest production designs include:

• Regenerative Braking – active braking during motor deceleration phase, providing instantaneous response to the flight controller commands and matched-response to acceleration profiles (less “float” during flight).
• Temperature-Controlled Synchronous Rectification – new proprietary algorithm for smooth-running motors at low-throttle and improved, faster response under high-peak loads; all while significantly increasing flight-time efficiency and reducing operating temperatures.

KDE Direct offers a wide-range of UAS Brushless Motors, from small 2S motors for lightweight applications to industrial-grade motors supporting 14S and higher voltagmifumo ya e.

The KDE Direct DMA provides the ability to update and program the KDE Direct UAS Brushless ESC Series to the latest production firmware releases, and customize advanced options for multiple applications. Advanced technologies, such as Synchronous Rectification and Regenerative Braking, can be enabled to enhance performance and optimize control algorithms.

DEVICE INSTALLATION AND WIRING

Pay close attention to proper wiring as shown in the diagrams. The ESC is automatically powered via the USB DMA when using the Programming Lead (orange-red-brown cable). External power is NOT required to properly arm and program the microcontroller in most cases.

If the ESC does not include the dedicated Programming Lead or does not connect, a 9V to 12V power source (2S or 3S LiPo preferred, 25V maximum) is required for powering the ESC during programming. Once external power is properly applied to the ESC, the microcontroller is programmed via connection of the DMA to the Control Lead (white-red-black cable).

DEVICE MANAGER SOFTWARE INSTALLATION

1. Download and install the Device Manager software from the KDE Direct Device Manager Adapter (DMA) webukurasa katika: www.kdedirect.com/products/kde-dma
2. Complete the software installation (and all prerequisites) and launch the KDE Device application from the Windows start menu or desktop shortcut.
3. Connect the Device Manager Adapter (DMA) to a USB port.
   • The LED on the DMA will change from red to green upon recognition.
   • The Adapter Status will change from red to green in the PC software.
4. Connect the ESC to the Device Manager Adapter, ensuring proper orientation of the 3-wire plug (refer to the diagrams in Device Installation and Wiring).
   • The Device Status will change from red to green once the ESC is detected in the PC software.
   • Note: The software will not recognize the ESC if connected incorrectly.
   • Detection may take up to five (5) seconds as the ESC boots and its settings are read.

ESC PROGRAMMING AND FIRMWARE UPDATE

1. Download the latest production firmware file (make sure to choose the appropriate version for your ESC model) from the KDE Direct webtovuti kwa: www.kdedirect.com/products/kde-dma
2. Update the ESC to the latest production firmware release by pressing the “UPDATE FIRMWARE” button in the Device Manager software and selecting the downloaded firmware file (.kde).
   Do not disrupt power or connection to the ESC or Adapter during the update process, or corruption of the firmware and permanent-failure of the ESC can occur (6ESC can be restored in most cases via the “REPAIR MODE” feature).
3. When update is completed, the default settings will be automatically applied to the ESC and confirmed (allow up to five (5) seconds for this to complete).
   • Default Settings can be reapplied by pressing the “DEFAULT SETTINGS” button in the Device Manager software (allow five (5) seconds to pass before unplugging). Select the motor edition (if available) to optimize control the KDE Direct UAS Multi-Rotor Brushless Motor Series.
4. Disconnect power from the ESC (if required), then disconnect the Adapter from the ESC Programming Lead or Control Lead to complete the update.

ESC PROGRAMMING AND ADVANCED SETTINGS
NOTE: The Device Manager Software allows for the adjustment of advanced ESC settings and flashing ESC firmware. Modifying control algorithms can improve system performance for UAS and multi-rotor applications.
* Bold indicates default settings

STARTUP POWER

1. Default calibration for Manual and Range mode is 1100gs to 1940gs and changes will be stored in the EEPROM memory. When changing the Throttle Calibration Mode, EEPROM memory will automatically reset to this default range for safety before calibration.
2. Voltage-cutoff should always be “OFF” for UAS and multi-rotor flight applications, or a potential loss of flight stability and control can occur during low-voltage events. Voltage-cutoff is advantageous for single-rotor and fixed-wing applications as desired
3. Arming tones are provided as three notifications: (1) power application to the ESC via the power-input leads and failsafe-operation state, (2) voltage supplied to the ESC via LiPo cell count, and (3) receipt of flight-controller and/or receiver arming signal for armed and ready- operation state. The arming tones selection of “INITIALIZE” will not provide the failsafe- operation state tones, so special care is needed to ensure safe operation before the appropriate arming signal is received to the ESC for ready-operation state.
4. Propeller Hold rapidly decelerates and stops the propeller when the throttle reaches minimum value (0% position). Make sure this throttle value does not occur during flight in multi-rotor applications, or an immediate loss of flight control can occur. Propeller Hold is designed for emergency parachute recovery systems and/or operation in high-wind conditions (for quick deceleration of the propeller after landing) and activated via minimum throttle-hold position, to prevent propeller blade rotation and parachute cord strike. Also applicable for fixed-wing applications — allowing for propeller blade fold-back and aerodynamic-drag reduction. KDE Direct is not responsible for damages or injuries when using this specialized function — make sure to understand the requirements for proper operation before enabling. The final arming tones (last 2 beeps) will repeat again which indicates that propeller hold is ENABLED.
5. 0verload Protection will decrease the maximum current output to the continuous rating of the ESC (i.e., 95.4 for the 954 ESC) when triggered over a five (5) second interval. The ESC will not allow amperage higher than the rating until the next initialization or power-cycle (reboot).
6. Repair Mode provides the ability to force upload firmware to the ESC, in the case of data corruption from a power-outage or other unusual event. Upon connecting the ESC to the Device Manager Adapter, turn on Repair Mode by selecting the available checkbox and wait for the software to reconnect to the ESC. Once the DEVICE STATUS has turned green solid-fill, press the UPDATE FIRMWARE button to upload the correct firmware file. Upon completion, unselect the Repair Mode checkbox and the software will again reconnect and read the parameters for the Advanced Settings from the internal MCU. Repair Mode allows the install of any firmware file edition — make sure the appropriate version is selected before installation, or incorrect operation of the ESC can occur and potential damage beyond warranty coverage.
