Profile
The Takyon Z14120 Electronic Speed Controller (ESC) is designed for
applications where high power and high reliability is of importance. Its
exterior (IP66 rated, IEC standard 60529) is sealed against dust and liquid
in order to prevent corrosion, while excellent heat dissipation capabilities
enable it to function stably during highly intensive periods of work. The
Active Protection functions extend the life of the ESC and prevent damage
from misuse, with a voice prompt from the motor connected to the ESC
notifying users if a fault occurs. The ESC’s data cable also works as a
backup throttle signal transmission cable for increased reliability and a
safer flight, when used together with the DJI N3 or A3 flight controllers.
DJI ASSISTANTTM 2 allows you to configure the timing, acceleration,
active braking, motor rotation direction and other parameters. Built-in
configurations, specifically for different propellers and applications, can be
selected to minimize setup time and risk. Upgradable firmware ensures the
Takyon series stays up-to-date with DJI’s latest motor control technology
and features.
Features
Active Braking Function
Broad Motor Compatibility*
Adjustable Output PWM Frequency
Batteries: 5S-14S LiPo
Maximum Continuous Current: 120 A
* Refer to Specifications (p. 14) for details.

Active Protection*
• Overvoltage protection
• Undervoltage protection
• Short-circuit protection
• Overheating protection
• Stall protection
• Redundant throttle signal transmission
Main and Backup Throttle Signal
• Main throttle signal: 30 Hz to 500 Hz PWM signal
• Backup throttle signal: Serial signal (DJI N3 or A3 flight controller required)
High Rotational Speed Motors
• 40000 rpm (7 pole pairs)
• 280000 rpm (1 pole pair)
PC Assistant Software
• Timing settings
• Voice prompt settings
• Active braking settings
• Motor rotation direction settings
• Throttle range settings
• Motor rotation direction testing
• Firmware upgrade
• Flight data export
Typical Applications
• Agricultural multirotor aircraft
• Industrial aerial imaging multirotor aircraft
Active Braking: The motor actively provides a reverse torque
when decelerating, recovering some of the rotational energy.
Normal braking mainly relies on air resistance.
DO NOT use a direct-current power supply for testing to avoid
damage to the power supply when active braking function is
enabled.
* Refer to Active Protection Functions (p. 13) for details.

Connection
Tools Required: Power distribution board (PDB)*, electric soldering iron
and soldering tin
1. Solder the ESC’s black and gray power cables to the pads on the PDB.
2 Connect the signal cable to your flight controller. The signal cable’s gray
wire transmits the control signal and the black wire is for ground.
3. When using the Takyon Z14120 together with the DJI N3 or A3 flight
controller, connect the data cable (JST 3-pin) to the iESC port on the
flight controller via a smart ESC communication cable for redundant
throttle signal transmission.
4. Connect the motor to the ESC.

Ensure that there are no open circuits or short circuits when
soldering the ESC cables.
It is recommended that you solder a power connector on the
PDB for the battery.
Using DJI Assistant 2
DJI Assistant 2 is used to upgrade and configure the ESC.
• The DJI Updater for DJI Smart ESC is required but is not
included with the ESC. To use DJI Assistant 2, connect the ESC
to a computer through the Updater as shown below.
• To ensure your own safety, remove the propellers or disconnect
the ESC and motors before using DJI Assistant 2.
• Unplug any other serial devices that are connected to your
computer before using the Updater.
ESC
Updater for
DJI Smart ESC
Computer
1. Download and install DJI Assistant 2 from the official DJI website.
http://www.dji.com/takyon-z14120/info#downloads
2. Connect the Updater to the ESC with the data cable and to your
computer with a Micro USB cable.
10 © 2017 DJI All Rights Reserved.
3. Connect a battery (5S - 14S LiPo) to supply power to the ESC. Do
not disconnect the ESC from your computer or the power supply until
configuration is complete.
4. Launch DJI Assistant 2. When a connection is established, the software
will display the connected devices.
5. Click the Settings tab for basic settings such as Active Braking,
Timing, Motor Rotation, Startup Tone, etc. Click the Advanced
Settings tab for Output PWM Frequency Settings. Click the Data
Recorder tab to view and export flight data.
6. Click Firmware Update to 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.
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 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.

Using the Remote Controller for ESC Configuration
Be sure to remove the propellers before configuring the ESC.
Calibrate the throttle range and switch the motor rotation direction using
the remote controller:
1. Power on the remote controller and receiver. Ensure a good communication
between them.
2. Push the throttle stick all the way up, connect the ESC to the motor
and power on the ESC. The motor will start beeping, alternating
between a double beep and a triple beep with a two-second gap
between each beep. To configure the ESC, carry out each of the
following movements within the two-second gap.
a. Throttle Range Calibration
After the double beep, pull the throttle stick all the way down. A
1-second beep will sound if calibration is complete.
b. Motor Rotation Direction Switch
After the triple beep, pull the throttle stick all the way down. A 1-second
beep will sound once motor rotation direction has been switched.
