52 Operation Theory
As in the diagram below, 2-axis linear interpolation means to move
the XY position from P0 to P1. The 2 axes start and stop simulta-
neously, and the path is a straight line.
The speed ratio along X-axis and Y-axis is (?X: ?Y), respectively,
and the vector speed is:
When calling 2-axis linear interpolation functions, the vector speed
needs to define the start velocity, StrVel, and maximum velocity,
MaxVel.
4.2.8 Two Axes Circular Interpolation Mode
Circular interpolation means XY axes simultaneously start from
initial point, (0,0) and stop at end point,(1800,600). The path
between them is an arc, and the MaxVel is the tangential speed.
Notice that if the end point of arc is not at a proper position, it will
move circularly without stopping.
