190 Motion Control Theory
a. Enable/disable point table function
Please enable the point table function, set up its ID (0~1),
movement dimension and axis number before using it. Please
disable it after the point table function is ended.
I32 APS_pt_enable (I32 Board_ID, I32 PtbId, I32 Dimension, I32
*AxisArr);
b. Monitor buffer space and fill in the points
A point table features 50 buffer points. You may monitor these
buffer points and fill in the table with movement commands (see
Section 4.11.1 for detail) by loading in all the graphic points
dynamically.
c. Start /stop point table movement
After enabling the point table and fill in the buffers with movement
commands you can then start up the point table function. The
motion kernel program starts executing movement commands
contained in buffer points in sequence until interrupted or each
buffer point has been executed.
