Manual PID Tuning
For novice DYS 3X users we do not recommend immediately
diving into motor and PID tuning. This section is for advanced
users who are familiar with all the parameters of the software.
Always remember to make a backup of your profile settings
so you can easily reload and have record of your original PID
settings!
Prerequisites:
To start with fine tuning your PIDs you should have your
original DYS 3X Profile settings loaded. Your motor polarity
should be correct and your IMU sensor should be calibrated
and configured properly.
Tuning is achieved by referencing the Real Time Data tab in
the GUI. You should have the gimbal on a table mounted
and locked to the DYS 3X stand. The battery should be fully
charged for the tuning process.
Tuning Process:
Set gimbal to Profile 4 (LOCK MODE) Start with the PITCH axis,
then ROLL then YAW. Begin by deflecting the camera with
your hand on each axis and watch the speed and
smoothness of the return action of the GYRO data on the
Real Time Data graph. Your goal in tuning is to raise the P and
D value for each axis as high as possible without causing high
frequency feedback or unwanted vibrations.
i.
Set “I” to a small value of 0.04 or less.
ii. Slowly increase “P” until the motor starts to oscillate.
iii. Increase “D” in small increments until the oscillations
stop.
iv. Repeat steps ii and iii until high-frequency vibration
occurs. You may feel the vibration by hand and see a
noisy line on the gyro graph. At this point, you have
identified the maximum values for “P” and “D” for
