4.12 2D Interpolation
“Interpolation between two axes” means the two axes start simultaneously
and reach their ending points at the same time. For example, in the figure
below, we want to move the axes from P0 to P1, and hope the two axes start
and stop simultaneously at a period of time ?t. Then the moving speed along
X-axis and Y-axis will be?X/?t., ?Y/?t, respectively.
The interpolation function of PCI-8136M has similar format. For example, a
S-Curve 2-axis (2 and 3) linear interpolation:
int16 AxisArray[2]={2,3}
_8136_Start_S_Move_XY(CardNo, AxisArray, Px, Py, Start_V,
Max_V,Tacc,Tdec)
The first axis at the axis array of interpolation functions is the main axis, and
the other axis is the secondary axis. The speed relation between main and
secondary axes is as follows:
Composite Speed = Speed of main axis x
X-Axis
Y
-Axis
