5. Set the limits.
In order to prevent damage to cables and other equipment, you can
set limits to the range of physical travel of the head movement and
lens controls.
For example to set the limits in the LFP controller you use the menu
option
SET SOFT LIMITS
.
Hint
The homing facility on the SFH-50 head uses optical sensors
(with homing fins) on the Pan and Tilt axes. The optional Roll
facility uses a magnetic sensor. There are two magnets on the
Roll ring, so the Roll homing facility will work for both
over-slung and under-slung mount configurations. For either
configuration, note that the camera platform is not horizontal
in the Roll home position. This is intentional, as it makes the
homing procedure quick and directionally reliable when you
invoke the homing facility from a typical horizontal (or
near-horizontal) platform starting position, whether the camera
is over-slung or under-slung.
Hint
If your SFH-50 has a
Roll Ring, set a Tilt
limit within ±90° of a
horizontal platform in
order to avoid
damaging the Roll
motor cable which goes
through the hole in the
centre of the Tilt axle.
