correct one for your particular SFH-30 head model and connection
method.
3. Set the control directions.
In your controller or software you need to specify the directions of
the focus, zoom and joystick/handwheel controls for your particular
head, lens gearing attachments, and preference. For example, some
people prefer the camera to point upward when the joystick is pulled
back, while others prefer the opposite logic whereby pushing
forward (“up”) on the joystick targets the camera upward in the
scene.
For example to set the control directions on an LFP controller you
use the menu option
SET DIRECTION
. On the MSA-20 Handwheels,
Joystick Controller, or Mini MSA you can use the same menu option
or use the
FWD
and
REV
hardware switches.
4. Zero the axes.
At the beginning of each session, after loading the head, you need to
zero the axes . This defines a base position at which all head
positions and lens settings are set to zero (0) in the controller or
software. All limits, lens controls, preset positions, and moves that
are stored in the controller or software are measured relative to this
base position. The zero points themselves are not stored in the head
or lens when the power is off, so you need to define them at the start
of each session, by zeroing the axes. Controllers usually offer two
different ways to zero the axes: an
automatic method and a manual
method:

In the automatic method (sometimes called homing ), the
controller physically moves the axes to the home positions that
are built into the hardware (if your head has the optional
homing facility) and then assigns these positions as the zero
points for the axes. For example to automatically zero the axes
with an MSA-based controller (such as the LFP, MSA-20
Handwheels, Joystick Controller, or Mini MSA) you can go
into film mode and use the menu option
HOME AXES
>
ALL
AXES
.

In the manual method (sometimes called direct zeroing ) you
use the controls to point the camera head in the direction that
you want to use as the zero position for the head axes and then
manually set the current axes positions as the zero points. For
