Pedestal Control Command Type 1
Function
To assign movable range in Pan direction.
Command 0064h
Length 9
byte
Normal Mounting: –889~+889 (7C87h~8379h)
Parameter
Range
Inverse Mounting: –1511~+1511 (7A19h~85E7h)
Status None
Reference •Maximum & minimum (position) movable angle can be set, when Pan motion
command is set by
Pan Right Start
and
Pan Left Start
are executed.
•To set Pan 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
12.17
)
•Minimum parameter value can be obtained by
Pan Minimum Angle
Request
command (
12.19
) and maximum value can be obtained by
Pan
Maximum Angle Request
(
12.20
).
•Parameter section (9byte) splits minimum angle (position) as p1~p4 and
maximum angle (position) as p5~p8.
•Minimum & maximum Pan 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, move to
Home Position
, even
though out of range.
•In case that Pan position is out of range before executing
