6.9  Linear and Circular Interpolated Motion 

@ Name 

_8132_start_move_xy – Perform a 2-axes linear interpolated motion 

between X & Y without waiting 

_8132_move_xy – Perform a 2-axes linear interpolated motion 

between X & Y and wait for completion 

_8132_arc_xy – Perform a 2-axes circular interpolated motion 

between X & Y 

 

and wait for completion 

_8132_arc_xy – Perform a 2-axes circular interpolated motion 

between Z & U and wait for completion 

_8132_recover_xy – return single axis motion mode   

@ Description 

_8132_move_xy, _8132_start_move_xy: 

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. 

_8132_arc_xy: 

These two functions cause the axes to move along a circular a rc 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. 

_8132_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. 

_8132_recover_xy: 

   After using _

start_move_xy, use must use this function for next 

single PTP axis motion
