8.9.3 Sample Program (Rewriting Positioning Tables)
The operation for rewriting positioning tables using a user program is mainly divided into five
steps.
• Specify the axis number, table number and table size to rewrite the positioning table.
• Set the positioning data to be rewritten.
• Set the positioning data in the positioning data setting area in buffers.
• Execute reading or writing the data in accordance with the requests stored in buffers.
• Execute recalculation.
(Note): The sample program on the next page is for rewriting the positioning data of one table from the table number
1 of the axis number 1 for the FP7 MC Unit installed in the slot number 1.
