4.4.7 Speed Control Modes

Description
By default, position control commands are independent from the speed
control commands. In this independent control mode, the commanded speed
is an unsigned magnitude that determines the speed at which independently
commanded positions are effected, and the execution of these speed
commands do not affect the commanded desired positions themselves. This
mode is appropriate for pure position control methods (when pan-tilt control
is effected solely by commanding pan-tilt position) and hybrid position-
velocity control methods (when pan-tilt positions and the rate at which they
are achieved are both controlled).
in which all pan-tilt control is effected by signed changes in command axis
