COMMAND REFERENCE PTU-D46 User’s Manual (v2.14.0)
Related Topics
• Position resolution (units): See Section 4.3.3
• Symmetric trapezoidal acceleration is used, so the rate of deceleration is
equivalent to the rate of acceleration
• Acceleration cannot be changed on-the-fly since it takes several seconds to
recompute the internal tables used to rapidly execute speed ramping.
4.4.5 Base (Start-Up) Speed
Description
Specify or query axis base (start-up) speed. Base speed is specified in
positions/second. Defaults to 1000 positions/sec.
Syntax
Query desired pan base speed: PB<delim>
Set desired pan base speed: PB<positions/sec><delim>
Query desired tilt base speed: TB<delim>
Set desired tilt base speed: TB<positions/sec><delim>
Example
The following commands home the pan axis, moves it far left, changes the
base rate, then moves back to home:
I *
PP0 *
A *
PP2600 *
PB * Current Pan base speed is 1000 positions/sec
PB1000 *
PP0 *

• Speed bounds: See Section 4.4.6
• Changes in the base rate cannot be made on-the-fly since it takes several
seconds to recompute the internal tables used to rapidly execute speed
ramping.
4.4.6 Speed Bounds
Description
Set and query the upper and lower speed bounds for desired speed
commands.
Syntax
Query upper pan speed limit: PU<delim>
Set upper pan speed limit: PU<positions/sec><delim>
Query lower pan speed limit: PL<delim>
Set lower pan speed limit: PL<positions/sec><delim>
