COMMAND REFERENCE PTU-D46 User’s Manual (v2.14.0)
Because speed, acceleration, and position are precisely controlled, you can accurately and
simply predict the position attained by the pan-tilt unit in time.
4.4.2 Speed (absolute)
Description
Specify or query desired axis speed. Desired speed is specified in positions/
second and it can be changed on-the-fly. The speed specifies that rate at
which the pan-tilt move to achieve position movement commands.
Desired speed commands outside the speed bounds return an error and
are not executed.
Syntax
Query desired pan speed: PS<delim>
Set desired pan speed: PS<positions/sec><delim>
Query desired tilt speed: TS<delim>
Set desired tilt speed: TS<positions/sec><delim>
Example
The following commands instruct the pan axis to move to the far left, then
slowly move right, and then on-the-fly it speeds up:
I *
PS2500 *
PP2600 *
A *
PS600 *
PP-2600 *
PS2500 *
