Arguments
•
end_1
The end position for the
BASE
axis.
•
end_2
The end position for the next axis.
•
centre_1
The position around which the
BASE
axis is to move.
•
centre_2
The position around which the next axis is to move.
•
direction
A software switch that determines whether the arc is interpolated in a
clockwise or counterclockwise direction. Value: 0 or 1.
If the two axes involved in the movement form a right-hand axis, set
direction to 0 to produce positive motion about the third (possibly imagi-
nary) orthogonal axis. If the two axes involved in the movement form a
left-hand axis. set direction to 0 to produce negative motion about the
third (possibly imaginary) orthogonal axis. See the table below.
