All directions are given from a camera operator's point of view. For example, camera-right
side refers to the right side of the camera when standing behind the camera and operating
it in a normal fashion.
The appendix at the back of the manual contains useful reference material including
specifications, connector pin-out diagram.
Before use, please ensure that all users comprehensively read, understand, and follow the !
instructions in this document. !

1.1 Risk Levels and Alert Symbols!
!
Safety warnings, safety alert symbols, and signal words in these instructions indicate
different risk levels: !
!
!
!
DANGER indicates an imminent hazardous situation which, if not avoided, !
will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided,
may result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
NOTICE
NOTICE explains practices not related to physical injury. No safety alert
symbol appears with this signal word.
NOTE
Provides additional information to clarify or simplify a procedure.

PID
!
Proportional – Integral – Derivative controller (PID controller)!
!
!
!
!
Proportional – Integral – Derivative controller (PID controller)!
A PID controller continuously calculates an error value e (t) as the difference between a !
desired setpoint (SP) and a measured process variable (PV) and applies a correction !
based on proportional, integral, and derivative terms (denoted P, I, and D respectively) !
which give the controller its name.!
!
Term Pis proportional to the current value of the SP − PV error e(t). For example, if the !
error is large and positive, the control output will be proportionately large and positive, !
taking into account the gain factor "K". Using proportional control alone in a process with !
compensation such as temperature control, will result in an error between the setpoint and !
the actual process value, because it requires an error to generate the proportional !
response. If there is no error, there is no corrective response.!
Term Iaccounts for past values of the SP − PV error and integrates them over time to !
produce the I term. For example, if there is a residual SP − PV error after the application of !
proportional control, the integral term seeks to eliminate the residual error by adding a !
control effect due to the historic cumulative value of the error. When the error is eliminated, !
the integral term will cease to grow. This will result in the proportional effect diminishing as !
the error decreases, but this is compensated for by the growing integral effect.
Term D is a best estimate of the future trend of the SP − PV error, based on its current rate !
of change. It is sometimes called "anticipatory control", as it is effectively seeking to reduce !
the effect of the SP − PV error by exerting a control influence generated by the rate of error !
change. The more rapid the change, the greater the controlling or dampening effect. !

PID Quick Setup!
NOTE Start with a solid camera setup
1.0 Set Ramp to ZERO on the Joystick (Pan & Tilt) (K4, K5, K6)
2.0 Physical testing of the head motor power:
2.1 Touch the Tilt axis and try move the camera
down and check if the camera slipping. !
!
2.2 If the tilt axis is slipping, you need to
increase motor power for the tilt axis.
2.3 Use the resulting Tilt value as !
starting value for the Pan axis.!
2.4 Press Save
3.0 Adjusting the PID values:
NOTE First you will need a camera picture
3.1 Select a point in the set.
3.2 Use the joystick to pan and stop the head !
at the selected point in the set.
4.0 Check if the camera: !
4.1 stops at the selected point!
4.2 or if the camera is over driving the point!
4.3 or if the camera is bouncing left and right
5.0 If the camera is over driving or bouncing,
you need to work on the Pand Dvalue !
of the Pan axis.
Adjust the Pand Dvalues by steps of five !
up or down.
5.1 If the head is still bouncing because a too soft damper
in between the Head and Crane, increase the Ramp
on the Joystick to slow down the mass before the targeted
end position.
5.2 Same procedure for Tilt
Conclusion:!
It is important to understand that the entire system, such as camera setup, the attachment
of the SRH-3 head to the crane and the overall quality of the crane itself must be
considered.
!
For example:!
If a too soft Iso Damper is used and the whole system becomes too elastic and therefore it
the head may begin to shake. But if a suitable Iso Damper with the right dimensions and
hardness is used, the maximum performance of the SRH-3 can be used.
!
PID

!
!
!
!
If there is mechanical play between the components in the shock absorber, !
vibrations of the overall system may occur.
!
In order to use the maximum power of the SRH-3, it must be ensured that all !
involved components are optimally designed for the task.
If you want to read a truly detailed description of Stabilization as it applies to Film & TV,
we strongly recommend the following :
http://www.pv-labs.com/wp-content/uploads/2014/12/Stabilization-Steering-and-Gimbal-Technology.pdf
!
!
7.5
Drop!
Permanently compensates of the Pan and Tilt for the !
changing lever and weight distribution of the camera, !
when the camera is facing down.!
!
!
!
!
If the camera is tilted downwards on the tilt axis, the overall !
length of the camera will be shortened, as well as the weight !
distribution.!
The compressed weight distribution can lead to !
overcompensation of the Pan axis.!
The Drop function will help to prevent this.!
!
The motor power of the Pan axis is regulated down in !
proportion to the tilt angle.
Depending of the length and weight of the camera, the !
proportional compensation value can be adjusted from !
0% to 100%.
7.6
Top Down
When extreme camera angles will be reached,
such as 90° tilt down, the entire head and crane
set up may start to vibrate
A higher Drop compensation will be needed.
NOTE
Ensure that the camera setup is rigid.!
The top support bracket will also help to
reduce unwanted vibrations.

Autotune (Beta)
The SRH-3 offers Autotune which will help to find the needed PID values. !
Autotune tries to calibrate strength and torque of the motors automatically.
NOTE
Autotune can only be used with camera setups heavier than 8 Kg / 17.3 lbs.
If the camera setup is below 8 Kg / 17.3 lbs, use the default values and set Power to 100.
Touching Auto will open a new menu.

Autotune procedure
This menu allows you to autotune each axis on its own,
or all three axes the same time.
Touching All PID Tune for example, will open
this screen.
NOTE
During autotune calibration, the head moves in all
single axes, which can cause vibration and possibly noise.
This is completely normal and there is no need to worry.
When the autotune has been completed, the PID menu
will show up again and will present the actual PID values.
Here you can accept the autotune PID values,
by pressing Save.
Or you Discard the autotune PID values, because they
do not reach your needs.
