3 2. Always fly your aircraft in areas free of people, animals, power lines, and other obstacles. 3. DO NOT approach or touch the motors or propellers when the unit is powered on. 4. Before takeoff, ensure that the propellers and motors are installed correctly and the propellers are unfolded. 5. Ensure that all parts of the aircraft are in good condition. DO NOT fly with worn or damaged parts. 6. Ensure that all parts are firmly in place and all screws are tight before each flight. 7. Only use compatible, authorized DJI parts. EN Introduction The E5000 Pro Tuned Propulsion System is designed for multirotor aircraft with a payload of kg/rotor. The system can be washed, making it ideal for industrial applications and aerial imaging in demanding environments. The brand new M motor features an integrated centrifugal cooling system and annular array of cooling fins to enhance heat dissipation. Reinforced blades and a perfected aerodynamic design minimize rotational inertia on the foldable 28-inch Z-Blade propellers to equip large platforms with sharp response. The 1280X ESC uses FOC (Field-Oriented Control) algorithms to allow for more motor responsiveness and precision control. Additional protection functions extend the life of the ESC. When used with the DJI N3 or A3 flight controllers, the ESC data cable handles communication with the flight controller and also acts as a backup throttle signal transmission cable for increased reliability and a safer flight. 1. Parts The Powertrain (CW or CCW, screws included), Smart ESC Communication Cable and Updater can be purchased separately on the DJI Online Store. Powertrain (CW) Powertrain (CCW) DJI All Rights Reserved.

4 Smart ESC Communication Cable Updater Screws Arm Screws (M4 14 Hex Socket) Propeller Adapter Screws (M3 11 Hex Cap) Tools and Materials Required: An hex key for arm screws (M4 14 hex socket), threadlocker, screw, corresponding holding base and wrench, or rivet and rivet gun for the mounting hole ( 4mm), electric soldering iron and soldering tin 2. Flight Controller Settings EN The E5000 ESC features a DJI optimized FOC algorithm to offer improved performance during rotor acceleration and deceleration. The gain values and power bandwidth must be adjusted according to your flight control system and airframe. The table below shows typical parameters when using the E5000 Pro with a DJI A3 flight control system, a six-rotor frame with a diagonal distance of 1600 mm, and at a takeoff weight of 35 kg: Basic Gain Sensitivity Gain Power Bandwidth Pitch Roll Yaw Throttle Brake Attitude 1% 1% 0% 0% 50% 0% 80% 3. Mounting the Powertrains Use a suitable airframe that can withstand the large thrust delivered by the E5000 Propulsion System. The powertrains are compatible with frame arms with an outer diameter of 30 mm. Mount the powertrains to appropriate frame arms only. Identify the clockwise and counter-clockwise marks on the propellers and mount the powertrains onto the corresponding frame arms. CW or CCW Mark Propeller Mounting Hole ( 4 mm) Powertrain Arm Motor Built-in ESC 2016 DJI All Rights Reserved. 5

5 Arm Screw Holes (M4) ESC Status Indicator EN 1) Pull the cables of the powertrain through the frame arm. Then insert the frame arm into the powertrain arm. 2) Align the components so that the propeller is oriented upright after assembly. 3) OPTIONAL: Use an appropriate screw and holding base or rivet (for the reserved mounting hole 4mm) for securing the position of the powertrain arm to achieve optimal performance. 4) Apply threadlocker to the two arm screw holes. Then insert and tighten two screws (M4 14 hex socket). Ensure the screw is secured tightly for the threadlocker to be effective. Ensure the threadlocker is completely dry and solid before flight to prevent the powertrain coming loose. 4. Connecting the Cables Power Cables (Red, VCC; Black, GND) Signal Cable (To the flight controller) Data Cable (For communication & firmware update) 1) Solder the red VCC cable and black GND cable of each powertrain to the frame s power system. Make sure that the solder points are strong and that there is no chance for a short circuit. 2) Connect the signal cable to your flight controller. The signal cable s red wire transmits the control signal; the black wire is for ground. 3) When using the powertrain together with the DJI N3 or A3 flight controller, connect the data cable to the iesc port on the flight controller via the smart ESC communication cable for real-time communication with the flight controller and redundant throttle signal transmission. Arrange the cable properly if not used, so that it will not interfere with other on-board devices DJI All Rights Reserved.

6 5. Using DJI Assistant 2 The DJI ASSISTANT TM 2 is used to update the ESC firmware. Be sure to remove the propellers before using DJI Assistant 2. Powertrain Updater Computer Before using the Updater, unplug any other serial devices that are connected to your computer, then follow the instructions below: 1) Download and install DJI Assistant 2 from the official DJI website. ( 2) Connect the Updater to the powertrain with the data cable and to your computer with a Micro USB cable. 3) Connect a 12S LiPo battery to the powertrain to supply power to the system. Do not disconnect the powertrain from the computer or power supply until the configuration is complete. 4) Launch DJI Assistant 2. When a connection is established, the software will display the connected devices. 5) Click under Connected Devices to enter the firmware update page. Check the current firmware version and ensure the installed firmware is up to date. If not, login with your DJI account and click the Upgrade button. EN If your ESC is not recognized by DJI Assistant 2 (no connected devices): Check if there is more than one FTDI device connected such as another DJI Updater, an FTDI USB adapter or development board (e.g. a BeagleBone, Raspberry or Arduino board). Unplug the other FTDI devices, restart the ESC and DJI Assistant 2, and try again. Re-connect the ESC and the power supply in the following order: Connect the ESC to your computer, connect the power supply to the ESC, and then launch DJI Assistant 2. When using the ESC together with the DJI N3 or A3 flight controller, connect the data cable to the iesc port on the flight controller via the smart ESC communication cable to update all the connected ESCs firmware together in the flight controller page of DJI Assistant 2: Connect the flight controller to DJI Assistant 2 -> N3 or A3 icon -> Firmware Update -> ESC Firmware List DJI All Rights Reserved. 7

7 6. ESC Status Description The 1280X smart ESC s protection and alarm functions prevent damage and extend its lifespan. ESCs status is displayed by the ESC Status Indicator and notification sounds.

It varies periodically as a function of the rotor position. 9. FAQ EN How do I replace the propeller blades or propeller adapters if they are damaged? 1) Prepare two propeller blade screws (M6 22 hex cap), four propeller adapter screws (M3 11 hex cap), and four propeller washers. 2) Apply threadlocker to the screw holes on the motor and the propeller adapter. 3) Assemble the propeller and tighten with two propeller blade screws (M6 22 hex cap) so that the blades can fold smoothly. Mount the propeller onto the motor and use four propeller adapter screws (M3 11 hex cap) to secure the propeller. Propeller Blade Screws (M6 22 Hex Cap) Propeller Adapter Screws (M3 11 Hex Cap) Propeller Washers Ensure the screw is secured tightly for the threadlocker to be effective. Ensure the threadlocker is completely dry and solid before flight to prevent the propeller from flying off the motor. This content is subject to change.
