AXB-PT10/15/30 PosiTrack Camera Controllers
The following table lists parameters for the PosiTrack Camera Controllers Positional Commands.
Parameters - Send_Commands (Cont.)
Parameters Description
Time (optional) If specified, 0 to 255 in tenths of a seconds; if not specified, at
current rate.
Position 0 to 255; value of POT input. Corresponds to a position of the
unit. 0 is one end of the POT and 255 is the other end. Not
directly related to an output level voltage.
0 to 65535 when using the 'AD MODE x 10' command, or for pan/
tilt commands. Corresponds to a position of the unit. 0 is one end
of the POT and 65,535 is the other end. Not directly related to an
output level voltage.
Speed 0 to 127; where 0 is slowest and 127 is fastest (default).
Deviation 0 to 127; where 0 is most accurate but can have some jitter.
Default is 2, which means the position can be within +/- 2 from the
specified position.
Distance 0 to 127; distance from the specified position.
Ramp Time 1 to 255; time in 10ms increments that it takes the motor drives to
ramp up to speed.
Positional Commands
GAS
Sets the output to slow
down within the
specified distance of
the specified position
for future 'GxLxxx'
commands.
This command can be used for motor mode and servomotor speed modes.
Syntax:
"’G<output>A<distance>S<speed>’"
Variables (See Parameters - Send_Commands section on page 38):
G - output = 1 - 4
A - distance = 0 - 127
S - speed = 0 - 127
Example:
SEND_COMMAND CAM,"’G1A5S20’"
Sets PAN to speed 20 when within 5 of the specified position for future 'G1Lxxx'
commands.
GD
Sets the current
maximum position
deviation for future
position ('GxLxxx')
commands.
This command can be used for motor mode and servomotor speed/positional modes.
Syntax:
"’G<output>D<deviation>’"
Variables (See Parameters - Send_Commands section on page 38):
G - output = 1 - 4
D - deviation = 0 - 127
Example:
SEND_COMMAND CAM,"’G1D4’"
Sets PAN deviation to 4 for future 'G1Lxxx' commands. Output will stop when it is
within 4 of the specified position.
