Selecting the axes
Each DRW-1 module has a selection button for
P
an,
T
ilt and
R
oll, at the top.
Initially
R
oll of P T R will be selected and visible,
after the SRH remote panel had been connected
to the LBUS.
By pressing the button
P
an,
T
ilt and
R
oll, the desired
axis for each wheel can be selected.
NOTE
Ensure that each wheel is assigned to only one individual axis.
Avoid assigning two wheels to the same axis.
NOTE
A blue blinking LED indicates a problem in the LBUS daisy chain.

The brake
The DRW-1 wheels are equipped with a brake
lever, which goes back to the ARRI Gear Head.
The brake lever allows the operator to engage or
disengage the wheel from the selected motor axis.
NOTE
An
unlocked
wheel will be indicated by a
green
LED,
A
locked
wheel will be indicated by a
red
LED.
NOTE
Disengaging the wheels can also support operation.
When you need to reproduce a movement and you want the position of the crank
to be at a certain angle, for example at the end of the movement, than first move the
head to the desired end position, disengage the wheel and bring the crank to the
required angle.
Now engage the wheel again and move the head backwards to the starting point.
Start the movement from the beginning.
7
Fluid Drag Ring (friction)
The DRW-1 wheels are equipped with a fluid drag ring,
which allows friction to be adjusted.
This unique feature allows the operator to control the
accuracy of the head through a mechanical friction
adjustment instead of a software value such as ramp.
Due to the mechanical friction, the ramp values
in the remote control can be set to 0 or close to 0.
The mechanical friction ensures that the DRW-1 wheels
and remote head respond quickly and accurately.
