Function Library
set_arc_division:
This function specifies the maximum angle (in degrees) between
successive points along the arc. The default is 5 degrees.
arc_optimization:
This function enables (
optimize =
TRUE
) or disable (
optimize =
FALSE
) the automatic calculation of the optimum acceleration for an
arc. The default state for arc optimization is enabled. When
arc_optimization()
is enabled, circular intepolation is greatly
improved by choosing the best acceleration for the motion. The
optimum acceleration is given by the following formula:
A
opt
= V
2
/d;
where A
opt
, is the best acceleration, V is the
set_move_speed()
velocity, d is the segment length. If the acceleration is higher than A
opt
,
the linear portions may be noticeable. If the acceleration is lower than
A
opt
, the motion will be slowed during the arc and it will lose its
roundness. Both
arc_xy()
and
arc_zu()
automatically change the
acceleration to A
opt
during the circular interpolated move.
set_move_ratio:
This function configures scale factors for the specified axis. Usually,
the axes only need scale factors if their mechanical resolutions are
different. For example, if the resolution of feedback sensors is two
times resolution of command pulse, then
ratio = 2
.
