The camera can only be set to a motion control mode when
the “NORM/PS” switch is in “PS/CCU” position.
When an external control mode is enabled, the camera will
close the control loops and position the shutter and transport
in the mid shutter closed position.
The adjustable sector will be set to 180 degress if the mode
allows external control of the adjustable sector, otherwise
it will set to position which was set in the camera.
When the “NORM/PS” switch is set to “NORM” during
motion control mode the control loops will be disabled
and the camera can be loaded or a gate check can be
performed. The camera will re-enter the selected motion
control mode when the switch is set to “PS-CCU“ again.
Note: The camera will indicate the actual frame count
but will not reposition the film to the framecount
where the motion control mode was left for
reloading/gate checking.
Note: The camera checks for any overacceleration/
overspeed and will exit motion control mode if
any error occurs.
See
Appendix
for motion control error codes.
Attention: The external controller has to take care
if the capping shutter has been withdrawn from
the gate before filming. When the phase
relation of the transport and the shutter motor is
shifted exposure will happen during the pulldown
which will result in blured images.
Note: The ARRIFLEX 435 Advanced has a built in
supervisory function that prevents the camera
from being overdriven by third party motion
control systems. This supervisory function will
trip at the following limits:
155 fps +/- 5fps
100 f/s
2
Acceleration +/- 20 f/s
2
However, if you run the camera on a motion
control system above the following limits
96 fps
40 f/s
2
we recommend to shoot tests before starting
production.
