Introduction

The TG20 is a multi-function stabilizer for 360 video shooting, based on our

years of stabilizer development experience, is the most advanced 360 video

shooting stabilization platform to date. The technology built into the TG20 allows

the user easily use and bring world-class movement translation and stability to the

professional cinematographer's market.

TG20 comes with an independent high performance IMU module, no need

work with other controllers, so it can be use on any multi-rotors、drones、cars or

other platforms. High performance motor servo systems with position feedback

and IMU to communicate with our custom 32-bit processor, which processes

movement calculations in 0.001 seconds, this equates to control and stability

accuracy down to 0.01 degrees of translated movements, meaning your images

are going to be perfectly stable in all three axes of movement.

A GoPro power supply system built into TG20, it can be power 10 GoPro

simultaneously, so the customer no need worry about Gopro shooting time. A

buzzer can be generate sound synchronization signal for video post-processing

also comes with the TG20 .

extension rod is ok for use. When the diagonal dimension of the aircraft is above

1140mm, two extension rods needed.

Mounting the Damper Plate

Mounting the damper plate to the another end of the extension rod with the

M3×12mm screws, fix the screws tightly to prevent from loosening or dropping.

www.accsoon.com

After completing the above steps, the gimbal assembly is complete.

(a) One extension rod (b) Two extension rods

Mounting the Gimbal to the Aircraft

Use tube clamp to attach loading tube with aircraft tightly. The space between

two loading tube is 155mm.

www.accsoon.com

Instead of using loading tube ， use damper plate to attach to DJI

S900/S1000/M600 directly.

The Gimbal Safe Distance

The following figure takes the GoPro 4 as an example. The GoPro settings is:

the viewing angle is widest which is about 170 degrees, video aspect ratio is 4:3,

recording format is 30fps 2.7K or 60fps 1080p.

When there are 8 GoPro vertically mount onto the gimbal and the wide

viewing angle is in 4:3 mode, the minimum vertical safety distance is 30cm, the

viewing overlapping ratio of cameras is about 60%.

www.accsoon.com

When there are 4 GoPro vertically mount onto the gimbal and the wide

viewing angle is in 4:3 mode, the minimum vertical safety distance is 45cm, the

viewing overlapping ratio of cameras is about 10%.

When there are 2 GoPro mount onto the gimbal bottom and the wide viewing

angle is in 4:3 mode, the minimum bottom safety distance is 18cm，the viewing

overlapping ratio of cameras is about 50%.

Parameters

The parameters controls the behavior of the gimbal.

Power: This parameter will determine how powerful the gimbal will be in

holding the camera still. Slowly increase this setting until you feel an

oscillation, then reduce the setting until the oscillation subsides. It is

important to check that the setting you have set will not oscillate in any

www.accsoon.com

orientation.

Speed: This parameter will determine how quickly the gimbal back to the

original position when it is not there due to any external force. Slowly increase

this setting meanwhile drag the axis to make it return to the original

position, until the gimbal back to the original position quickly and without

any vibration.

Trim: This parameter offers accuracy compensation when the gimbal is

working in dynamic, such as frequent vibrating in all direction or moving.

When the value is too high the gimbal will oscillate， then the value should

be decreased properly.

NOTE: Firstly adjust the power value, then the speed value and finally the trim

value.

Follow Deadband: Flollow deadband defines a range in degrees of handle or

aircraft movement which will be ignored. In practice, this means that you can

move the handle less than the deadband and the camera will not pan. Once

you exceed the pan follow deadband threshold, the camera will begin to pan.

Follow Speed: This parameter means how fast the gimbal follow the aircraft

or handle movements.

Working Mode

Pan Follow: The gimbal pan axis always tracks the aircraft or handle

orientation, which means when the aircraft or the handle rotated left or right,

www.accsoon.com

the camera will move, smoothly following the aircraft or the handle rotation,

and stop at the appropriate angle.

Pan Lock: All three axes are in self-stabilized and the direction is locked.

Troubleshooting

NO.

The Problem

The Cause

What to DO

The gimbal keeps

drifting after

initialization.

(1)The TX trims are too

high

(2)The ambient

temperature is too low

(1)Adjust the TX trims

(2)Wait for 1 to 2 minutes to

make the IMU warm

Some axis can not

keep horizontal after

initialization

(1)The default

calibration is wrong

(2)There is drift in gyro

(1) Do gyro calibration by

PC Assistant software or do

an offline gyro calibration

by RC

(2)Please contact Accsoon

customer Service if it still

cannot keep horizontal or it

moves irregularly after

initialization

The gimbal cannot

keep horizontal after

initial power on if the

ambient temperature

is lower than 10

degree

(1)The IMU wram up

time isn't enough

(1)Warm the gimbal for 2 to

3 minutes and wait until it

goes almost horizontally,

then quickly power off the

gimbal and power on it
