Pre-Set Positions & Profile Moves
Up to 64 pre-set positions can be stored and recalled in the head. (dependent on controller)
Each position includes, Pan, Tilt, Zoom and Focus positions. Once stored, the positions are
saved during power loss. Simply drive the head to the required position and
Store
this
position as a Pre-Set.
A major feature of the
Camball4
is that it always does a
Smooth
Profile Move
to
each pre-
set position. The profile of this move can be specified by the operator. By default, all axes,
Pan, Tilt, Zoom & Focus, move in the same amount of
time
to the pre-set position.
Default Total Time
= 4.5sec.
Default Ramp Up
= 1.5sec.
Default Ramp Down
= 1.5sec.
These settings are automatically stored but can be adjusted
at any time from the
Multi Function Controller
Total Time,
Ramp Up time, and Ramp Down time can be adjusted by
the operator for each pre-set position independently.
The Zoom start and stop times can be separated from the
Pan/Tilt start stop times.
The
Zoom Start
can be started before or after the main
Pan/Tilt move.
The
Zoom End
can be stopped before or after the main
Pan/Tilt move.
Fig.1 shows a profile move for Pan & Tilt. Zoom and Focus are not shown but are included in
the move. In the move illustrated, pan has further to move than tilt therefore pan moves at a
faster speed than tilt so that it stops at position 2 at the same instant as tilt.
Zoom also moves in the same time. Focus moves during the centre portion of the move so
that objects of interest are not de-focused during the start or end of the move.
