6.9 Linear and Circular Interpolated Motion
@ Name
move_xy – Perform a 2-axes linear interpolated motion between X &
Y
move_zu – Perform a 2-axes linear interpolated motion between Z &
U
arc_xy – Perform a 2-axes circular interpolated motion between X &
Y
arc_xy – Perform a 2-axes circular interpolated motion between Z &
U
@ Description
move_xy, move_zu:
These two functions cause a linear interpolation motion between two
axes and wait for completion. The moving speed should be set before
performing these functions. Relations of speed between two axes are
given in Chapter 4.1.4.
arc_xy, arc_zu:
These two functions cause the axes to move along a circular arc and
wait for completion. The arc starts from origin and continues through
the specified angle. A positive value for angle produces clockwise
arcs and a negative value produces counter-clockwise arcs. The
center of the arc is specified by the parameters x_center and y_center.
set_arc_division() function specifies the maximum angle(in degrees)
between successive points along the arc. The default angle is 5
degrees. The moving speed should be set before performing these
functions.
