  • Page 34: Gimbal Yaw Smooth Start/Stop

    GIMBAL GIMBAL YAW SMOOTH Smooth factor for gimbal controller, using to smooth control. The larger the value, START/STOP the smaller the acceleration of gimbal. MAX GIMBAL YAW SPEED This controls the max speed percentage at which the gimbal yaw. A higher value means a faster-moving gimbal and lower value means a slower gimbal.

  • Page 35: Stiffness Tuning

    GIMBAL STIFFNESS TUNING Stiffness setting has a significant impact on the performance of the gimbal. This setting adjusts the degrees 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 it is. GENERAL METHOD Start with a low value of 20 for all axes, then turn the motors ON.

  • Page 36: Hold Strength

    GIMBAL HOLD STRENGTH For heavy cameras, it’s suggested to increase hold strength for each axis by around 10% than the default values. 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”...

  • Page 37: Filter

    GIMBAL 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. GYPRO FILTER Defines the strength of the filter applied to Gyro sensor output.

  • Page 38: Others Gimbal Parameters

    GIMBAL OTHERS GIMBAL PARAMETERS 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.

  • Page 39: Imu Sensor

    IMU SENSOR The IMU sensor used in the PIXY SM is a combination of a high precision 3 axis gyroscope sensor and a 3 axis accelerometer sensor. IMU board is 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.

  • Page 40: Gypro Calibration

    (below -20C or above 50C) please re-calibrate the gyro. CALIB AT STARTUP: this feature is not available on the PIXY SM After Gyro Calibration, Gyro Offset X, Y, Z will change to a new value depending on the temperature.

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