INVERT – Reverse motor rotation direction. It’s extremely important to choose the correct
motor rotation direction to not damage your gimbal. To determine the correct direction, set
the P, I, and D values to 0 and the POWER values to 80 (or higher if your motors don’t
produce enough force to hold/move the camera). Level the camera tray horizontally and
click the AUTO button in the “Motor configuration” settings. The gimbal will make small
movements to determine correct motor rotation direction. Wait for the calibration
procedure to complete. Then, re-set your PID values and tune your Power values.
NUM.POLES – Number of motor poles. This value needs to be equal to the number of
magnets in your motor’s bell. During the “auto” calibration process described above, this
value is automatically detected. However, sometimes the auto calibration process is unable
to determine the correct number. Most brushless gimbal motors are built with 14 poles
(magnets) and utilize a DLRK winding scheme. Count your motor magnets and enter this
value if the “auto” value is not correct.
SENSOR – Configure your IMU by specifying the IMU sensor board’s orientation and
position on the gimbal. For a standard IMU sensor installation, look at the gimbal from
behind, like the camera view out from the gimbal. From this perspective, the up and right
direction will match the Z and X axis, respectively. You can place the IMU sensor in any
direction, as long as its sides are parallel to each motor axis. Take extra care in this step. It
is important to align the sensor precisely and mount it firmly. The correct configuration of
the IMU should result in the following:
1. Camera pitches forward – the PITCH arrow spins clockwise in the software.
2. Camera rolls right – ROLL arrow spins clockwise in the software.
3. Camera yaws clockwise – YAW arrow spins clockwise in the software.
SKIP GYRO CALIBRATION AT STARTUP – With this option, the board starts working
immediately after powering on, using the saved calibration data from the last gyroscope
calibration. Stored calibration data may become inaccurate over time or during temperature
changes, however. We recommend that you recalibrate your IMU on a regular basis to
ensure the best performance.
