12.28 Tilt Movable Range Assignment
Pedestal Control Command Type 1
Function
To assign movable range in Tilt direction.
Command 0064h
Length 9
byte
Normal Mounting: –267~+800 (7EF5h~8320h)
Parameter
Range
Inverse Mounting: –800~+89 (7CE0h~8059h)
Status None
Reference •Maximum & minimum (position) movable angle can be set, when Tilt motion
command is set by
Tilt Up and Down Start
Tilt motion setting command and
etc. and set Tilt maximum & minimum angle (position) which can be set by
Pan/Tilt Angle Assignment
command.
•Parameter value (1LSB) of Pan is equal to approx. 0.1125 by converting to
angle (see
12.18
).
•Minimum parameter value can be obtained by
Tilt Minimum Angle
Request
command (
12.21
) and maximum value can be obtained by
Tilt
Maximum Angle Request
(
12.22
).
•Parameter section (9byte) splits fixed value as p0, minimum angle (position)
as p1~p4 and maximum angle (position) as p5~p8.
•Minimum & maximum Tilt parameter value is to set at angle of
Home
Position
(8000h). See
12.25 Pan/Tilt Angle Assignment
.
•Not necessary to include
Home Position
between minimum and maximum
angle (position). But minimum angle value must set equal or less value of
maximum value.
•When
Pedestal Initialize 1
command executes, moves to
Home Position
,
even though out of range.
•In case that Tilt position is out of range before executing
Pedestal Initialize 2
command, it returns to minimum or maximum position within motion range
by the return motion.
