LFP Quick Start Guide

Limits are being
ignored or causing the
head to oscillate when
reached. The axes have not been zeroed. You must do
this at the beginning of each session just after
you load the head (page 10).
The
PRESETS
buttons
do not work
(Broadcast mode).
Can’t set limits, or the
head oscillates when
you set a limit. When you set soft limits (page 13) you must set
the
MAX
limit to the higher (or more positive)
axis value, and set the
MIN
limit to the lower
(or more negative) value.
After zeroing the axes (page 10), all the lens
axes (focus, zoom, and iris) should have a
MIN
value of zero (0) and for these axes you should
only change the
MAX
values. If you can only
move the focus, zoom, or iris axis into negative
values then it means you are using a lens with
external motors, and that the axis value is
increasing in the wrong direction on your
particular rig. To cater for this, see
Zeroing lens
axes with external Lens Control Motors on page
64.
The head moves too
slowly or too quickly
when zoomed in. The Zoom Related Speed (ZRS) feature
automatically slows the live pan and tilt
controls to cater for the narrow field of view
when zoomed in. You can adjust the amount of
slowing in the
SET ZRS
menu options (page
38).
The head moves more
slowly when zoomed
out. You are using a lens with external motors, and
the zoom axis value is increasing in the wrong
direction on your particular rig. To cater for
this, see
Zeroing lens axes with external Lens
Control Motors on page 64.
