Automatic Operation (Position Control)
8-48
8.9.2 Procedure of Rewriting Positioning Data
The following flowchart shows the flow of the operation required in a user program.
• For reading and writing, the operations to be executed (read, write) and targets (axis number,
table number, table size) are specified in the buffer control area of the unit memories.
• By executing “Recalculation” after the operation, the positioning data stored in the system
area of FP7 MC Unit is updated. Once the "Recalculation" is completed, the positioning
operation can be started for the rewritten positioning data.
