94 •Function Library
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.

@ Argument
axis: axis number designated to configure
n_axes: number of axes for coordinated motion
*map_array: specified axes number array designated to move.
str_vel: starting velocity in unit of pulse per second
