    New Alexmos Encoder Firmware Upgrade

    Alexmos Encoder 2.44b4 Encoder Tab

    Using encoders with SimpleBGC board gives the following advantages:

    1. Prevents motors from loosing synchronization and skipping steps.

    2. Provides the information about frame angle and angle of the camera relative to frame, that can be

    important for some kind of applications.

    3. Can significantly decrease power consumption by using field-oriented control strategy to drive

    motors.

    4. Increases instant torque the same way.

    5. Provides possibility to get information about the camera balance and makes automatic balancing

    (with help of extra DC servomotors and moving counterweights).

    6. Option to adjust camera position by hands.

    7. Increase the precision of stabilization by applying FOC-specific compensations.
