12.27 Pan Movable Range Assignment
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 Pedestal Initialize 2
command, it return to minimum or maximum position within motion range
by the return motion.
