  • 09. Powering Up The GREMSY T3

    After connecting to the power supply, the gimbal will perform series of alignments, self tests, which last about 5 seconds and will determine the status of the gimbal, indicated by the Status LED color. During this time, don’t touch the gimbal or camera.

    Always start the gimbal with a balanced camera set up otherwise after initialization the controller will return an error followed by a red color indicator.

     
    Step 1

    Make sure the Hyper Quick Release is mounted to the drone and its power port is already connected to the power supply correctly. Next, let’s mount the gimbal to the Hyper Quick Release, it will be automatically powered up.

     
    Step 2
    Wait about 5 seconds, do not touch the gimbal or camera.
     
    Step 3
    If the status LED is blinking green, the gimbal is ready for use. By default, the gimbal is in Follow mode if the motors are turned ON by the Function Button. Pan and tilt will hold the last orientation during turning on motor in follow mode so Tilt axis can be positioned to preferred orientation by hands.
     
    If the status LED is solid red, something is wrong with the gimbal and motors can not start. Connect to the software/apps to check details of the error message.
     
    Read “LED STATUS INDICATOR” in next section for more information.

  • 11. Operation Modes
    GREMSY T3 HAS 2 OPERATION MODES

    LOCK MODE: is a stabilization mode where the camera maintains orientation independently of the rest of the gimbal and the orientation can be changed by an external control signal from remote control.

    FOLLOW MODE: in this mode, the camera will mimic the operator’s movement and allows one person to control camera tilt and pan without using an external device like a remote control.

     
     
    GREMSY T3 Supports

    SINGLE OPERATOR: using FOLLOW mode.

    DUAL OPERATOR: a second operator can use a Remote Controller (SBUS, SPEKTRUM, PPM) to control gimbal’s movement.

     
     
    Working Operation
     

    GREMSY T3 has 2 working operations: Normal and Inverted.

     
    After powering up the gimbal , it will automatically detect if the gimbal is in inverted operation or normal operation based on pan motor position.
    During working, switching to other working operation made easy by changing pan motor position, the gimbal will automatically detect new type of working operation.
     
     
     
    Swithing Between Modes

    Using function button

    PRESS TIMES MODES
    Once time Turn motors ON
    2 times Lock mode
    3 times Follow mode
    Hold 3 seconds Turn motor OFF
    4 times Calibrate Gyros
     
     

    Using mode channel on remote control

    POSITIONS MODES
    High Follow mode
    Motors ON
    Midle Lock mode
    Motors ON
    Low Motors OFF
     
     
     

    Using software/application

    If there is a remote control signal, changing modes or turning motors on/off by other methods such as using the function button or software will not take effect because the remote control signal has the highest priority and override the command.

  • 14. Balancing
    To achieve the best performance from the T3, proper balancing is necessary. Accurate balance is critical in shots where the gimbal will be subjected to extreme movements or accelerations. There are 3 axes that need to be precisely balanced prior to powering up the gimbal.
  • 15. Mounting The Camera
    Use a 1/4”-20 screw to secure the camera to the camera tray, then put the camera to the gimbal and tighten the top bar screw.
     
     
  • 16. Mounting The Hot Shoe Adapter
    Use a provided hotshoe adapter to mount it onto hotshoe of the camera.
    For short cameras like Sony A6000/A6300 , hotshoe extension block shoud be used to increase the height
     
     
     
  • 17. Tilt Axis Front-Back Balance
    When the proper front-back balance is achieved, the camera will stay level when you remove your hands.

    1. Loosen the thumbscrew underneath the camera tray and the top bar screw. Then, gently slide the camera forward or backward until the tilt axis remains level.

    2. Tighten the thumbscrews to lock the camera and camera tray in position.

     
     
  • 18. Tilt Axis Vertical Balance
    When the proper vertical balance is achieved, you can rotate the camera in any angle and it will stay at that position.

    1. Rotate the tilt axis so that the lens is pointing upward.Then, loosen both vertical adjustment thumbscrews, gently slide the camera mount crossbar and the top bar forward and backward until the camera remains pointing upward when released.

    2. Tighten the thumbscrews. Check the number markings on both vertical rods are the same. Sometimes, the vertical balance could not be achieved, the front-back balance should be rechecked in this case.

     
     
  • 19. Roll Axis Balance
    When the proper left-right roll balance is achieved, the camera will stay level when you remove your hands.

    1. Loosen the thumbscrew underneath the roll bar, then gently slide the roll bar left or right until roll axis remains level.

    2. Tighten the thumbscrew to lock the roll bar in position.

     
     
  • 20. Pan Axis Balance
    Tilt the gimbal about 20 degrees from the verticality, identify if the gimbal is front heavy or back heavy. Slide the pan axis slider until the camera does not swing.

    1. Loosen the thumbscrew, then gently slide the pan axis slider backward/ forward until it doesn’t swing and stay at any given position when released.

    2. Tighten the thumbscrew to make sure pan axis slider is locked in position.

     
     
  • 21. Software - Tuning
    After the camera is balanced on the Gremsy, it’s time to fine tune some parameters for best performance.
     
  • 22. Stiffness Tuning
    Stiffness setting has a significant impact on the performance of the T3. This setting adjusts the degrees to which the gimbal tries to correct for unwanted camera movement and hold the camera stable. The higher you can run the setting without vibration or oscillation, the better.
     
     
    General Method
    Start with a low value of 20 for all axes then turn motors ON. Slowly increase this setting until you feel an oscillation in each axis, then reduce it until the oscillation subsides. You can touch the camera to feel the oscillation during tuning. Increase the stiffness setting 5-10 points at a time until oscillation appears then reduce 5 points until oscillation subsides.
     
     
    Step 01 - Tilt Stiffness

    Slowly increase this setting until you feel an oscillation in the tilt axis, then reduce the setting until the oscillation subsides. Make sure there is no vibration when tilting the camera up and down and when moving the gimbal in any orientation.

     
     
    Step 02 - Roll Stiffness

    Slowly increase this setting until you feel an oscillation in the roll axis, then reduce the setting until the oscillation subsides. Pick the T3 up and make sure there is no vibration when you move the gimbal around.

     
     
    Step 03 - Pan Stiffness

    Slowly increase this setting until you feel an oscillation in the pan axis, then reduce the setting until the oscillation subsides. Tilt the T3 about 20 degrees from the verticality and make sure that no vibrations are presented.

     
     
     
  • 23. Filter

    The purpose of the filters is to eliminate noise and vibration due to structural resonances in the camera, lens, or gimbal.

    Setting the filters too high or too low can cause signal disturbances that can reduce the overall stabilization.

     
     
    Gyro Filter

    Defines the strength of the filter applied to Gyro sensor output. If the gimbal has oscillations that cannot be corrected by adjusting stiffness settings, the Gyro Filter is used to further tune the gimbal and remove the oscillation.

     
     
    Output Filter

    Defines the strength of the filter applied to motors output. If the gimbal has oscillations that cannot be corrected by adjusting stiffness settings, the Output Filter is used to further tune the gimbal and remove the oscillation.

    1. If the gimbal is vibrating at a high frequency after tuning, increase the filter values.

    2. If the gimbal is oscillating or rocking at a low frequency after tuning, decrease the filter values.

     
     
    Default Values
    Gyro Filter 2
    Output Filter 3
     
     
     
  • 24. Expert / Advanced Settings

    There are some expert parameters that normally do not need to be adjusted. Leave these parameters at default settings unless they are required for troubleshooting.

     
     
    Hold Strength

    If “Auto power adjustment” is enabled, “Hold strength” will be the minimum power level required for the corresponding axis. The controller will automatically adjust power level from minimum to maximum level depending on the displacement between current angle and commanded angle.

    If “Auto power adjustment” is not selected “Hold strength” will be constant power level provided to the corresponding axis and should be adjusted manually. This option is only recommended for advanced users.

    For heavy cameras, it’s suggested to increase hold strength for each axis around 10% than the default value. If “Auto power adjustment” is not selected “Hold strength” will be fixed power level provided to the corresponding axis and should be adjusted manually. This option is only recommended for advanced users.

     
     
     
    Gain

    Defines how fast each axis will return to commanded position. To reload default expert settings just press “Default” in the expert menu.

     
     
    Default Settings
    HOLD STRENGTH TILT ROLL PAN
    40 40 40
    GAIN 120
    AUTO POWER ADJUSTMENT: ENABLED
     
     
     
  • 25. Follow Mode Settings

    The most widely used mode of single operation is Follow mode where the gimbal operator controls to pan and tilt of the camera. The camera movement will mimic the user’s input from the top-mount while the footage remains stable. The follow mode can be configured to be either very linear and robotic, or smooth and cinematic.

    Follow mode settings is available for Tilt axis and Pan axis.

     
     
    Speed

    Defines how fast camera will follow the movement.

     
    Smooth

    Smooth out the camera movement by adjusting this parameter. The higher the value is the smoother camera moves but at the expense of more delay in following the movements

     
    Window

    When the movement is out of the window zone, the camera starts to move. Within the window zone, the camera maintains its direction.

     
    Tilt Lock

    If this option is selected, the tilt axis will maintain its angle and only be controlled by remote control.

     
    AIRBORNE
    This feature is not available on the T3.
     
     
     
  • 26. Rotation Limit
    Travel of Tilt and Roll axis can be limited using UP LIMIT and DOWN LIMIT. The Pan axis keeps the ability to pan 360 degrees itself.
     
     
    UP LIMIT

    Set the up limit for Tilt or Roll axis (in 1 degree unit). The default values are -90 for Tilt and -45 for Roll.

     
     
    DOWN LIMIT

    Set the down limit for Tilt or Roll axis (in 1 degree unit). The default values are 90 for Tilt and 45 for Roll.

     
     
    ROLL OFFSET

    Set the Roll offset (in 0.1 degree unit) is only applicable when there is no remote control signal since remote control will override the roll angle. This is useful to fine trim the horizon. The default value is 0.

     
     
  • 27. IMU Sensor

    The IMU sensor used in the T3 is a combination of a high precision 3 axis gyroscope sensor and a 3 axis accelerometer sensor.

    IMU board is enclosed in a weather proof case and being heated where the temperature inside is controlled around 50°C with 0.2°C accuracy. Thanks to this feature, gyro calibration is no longer required in most situations.

    In order to provide extra high precision data output, the IMU is performed 6-point calibration at Gremsy factory.

    The T3 controller has a special algorithm to provide attitude estimation based on input data from the IMU sensor. This attitude estimation helps the controller to command motor output to compensate for camera movement.

     
     
    Gypro Calibration

    Thanks to temperature controlled and heated IMU, gyro calibration is not necessary as the gyro was calibrated at the factory and the temperature inside IMU remains constant around 50 degrees. However, if you notice drift during operation in extreme weather (below -20C or above 50C) please re-calibrate the gyro.

    CALIB AT STARTUP: this feature is not necessary on the T3

    After Gyro Calibration, Gyro Offset X, Y, Z will change to a new value depending on the temperature.

     
     
    Accelerometter Calibration

    Do not use this function, please contact Gremsy Support Engineers. Accelerometer sensor was calibrated properly at the factory to achieve accurate horizon level with special and precise equipment. Users do not need to do this unless it’s required for troubleshooting.

     
     
     
     
  • 28. Remote Control

    T3 supports SBUS , SPEKTRUM and PPM receivers. There are some parameters to be aware of before assigning channels to the receiver.

    SMOOTH: increasing this number will smooth out the movement of the corresponding axis but will also cause a delay.

    SPEED MODE: when speed mode is selected, the speed of the corresponding axis will depend on how far the stick position is from the neutral position. It is recommended that TILT and PAN channels should be set to speed mode.

    ANGLE MODE: when angle mode is selected, the corresponding axis will move to the angle set by current stick/knob position. It’s recommended ROLL channel should be set to angle mode.

     
  • 29. SBUS/PPM Settings
    Receiver Connection

    SBUS port is located on the Hyper Quick release and the gimbal controller. PPM port is located in the Roll housing.

    The receiver must be connected to correct wires order. The SBUS/ PPM port has 5V output to power the receiver, please do not use external power supply to power the receiver at the same time. Doing so may damage the electronic inside the gimbal.

     
     
     
    Channel Setting

    There are 6 channels to assign: MODE, TILT, ROLL, PAN, TILT SPEED, PAN SPEED.

    Assign MODE channel first then follow the order above because MODE channel is used to change operating modes of the gimbal and should be assigned to a 3-position switch as follows:

    • Switch at high position: FOLLOW MODE , MOTORS ON
    • Switch at middle position: LOCK MODE , MOTORS ON
    • Switch at low position: MOTORS OFF

    TILT and PAN channel should be in speed mode and ROLL channel in angle mode.

    TILT SPEED or PAN SPEED could be assigned to the same channel and should be assigned to throttle stick, dial, or other non-centering control on the transmitter.

    Below is an example of channel assignment to the Futaba T8FG.

    CHANNEL CONTROL NOTE
    MODE 5 SC 3 positions switch
    TILT 2 J2 Speed mode
    ROLL 4 T4 Angle mode
    PAN 1 J1 Speed mode
    TILT SPEED 3 J3
    PAN SPEED 6 RD

    Thumbscrew/top bar nut is not tightened Check tightening
    Camera mounting is not stiff enough Check camera mounting
    Filters settings are incorrect: Gyro and output filter should only be changed if other methods of reducing oscillation have failed Please read more in manual about Gyro filter and output filter (Advanced settings)
    Gremsy gimbal seems to be drifting Gyro sensor is drifting too much Re-calibrate gyro
    Motors seem to be weak Stiffness is too low Increase stiffness
    Auto-power adjustment is not enabled Check in Expert menu if Auto-power adjustment is enabled or not
    Footage appears to wobble side to side or up and down Camera is not properly balanced Check camera balance
    Stiffness setting is low Increase stiffness settings, start with the axis which is poorly stabilized. Higher Stiffness will achieve better stabilization. The tuning process is described in the user manual.
