I have the HiFly gimbal, a Sony FS100 camera with an old Zeiss lens and I simply cannot get my yaw axis to hold steady.
Motor is a GBM 8108-90. PID = 3-0.02-10, motor config power 190, "limit accelerations = 500 dg/sec2, Gyro thrust 80, "follow yaw" is not selected. Followmode is disabled.
Anybody have a similar setup...? Please share your PID settings.
In any case, As 200sx suggest the PID values should be higher, also 'I'
Have you verified the NUM.POLE and Inverted is correct?
Try setting P 15, I 0.05, D as high as needed, but not higher. After it worked like this try if you can get P higher, raise D just as much as needed. When it is working fine like this, raise 'I' as much as possible.
Ps. Is Yaw well balanced? I would verify this first.
Also where is your battery located, It is good to minimise the inertia of the moving parts, i.e. battery close to the Yaw motor (under or front) or at top of the handle would be good.
I have my pitch and roll balanced and tuned today. My pan/yaw is hard to balance, cannot move the whole thing more to the front... Have you balanced you pan/yaw perfectly? Can you turn your pan axis so its paralell to the top handle bar and have it stay there and in all other directions?
The only way I can "lock" my yaw is to have PID all to 0, as soon as I raise them, the yaw becomes unlocked. If I go above 3 on D a high frequency sound appears. Doesnt matter if "Follow YAW" is selected or not, the yaw does not follow...
so I set my motor power to 200 and then it holds the yaw. As soon as I enter numbers under PID it "unlocks" and if I go above 3 in D it starts to scream!
You have to properly balance the gimbal. Specially the 3rd axis once it doesn´t hold. If it is unbalanced when the gimbal is off it won´t hold even with the motors on.
