4.4.4 Acceleration

Description
Specify or query axis acceleration and deceleration for speeds above the base
speed. Acceleration is specified in positions/second
Syntax
Query desired pan acceleration: PA<delim>
Set desired pan acceleration:
Query desired tilt acceleration: TA<delim>
Set desired tilt acceleration:
Example
The following illustrate different rates of acceleration:
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 57 positions/sec.
Syntax
Query desired pan base speed: PB<delim>
Set desired pan base speed:
Query desired tilt base speed:
Set desired tilt base speed:
Example
The following commands home the pan axis, moves it far left, changes the
base rate, then moves back to home:
PA * Pan acceleration is 2000 positions/sec^2
PB * Current Pan base speed is 1000 positions/sec
PU * Maximum Pan speed is 2902 positions/sec
