8.5.2 Procedure of Rewriting

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 rewrtten positioning data.

 Recalculation
Recalculation is necessary after rewriting positioning data using user porgrams. The
procedure of recalculation is as follows. When recalculation is not performed, the operation is
executed with the positioning table before rewriting.
1．Change the positioning table in the unit memories.
2．Turn on the recalculation request (Y4) in the I/O area.
3．Confirm that the recalculation done flag (X7) in the I/O area is on. (Confirm that the
recalculation process is completed.)
(Note): I/O numbers of the recalculation request (Y7) and recalculation done flag (X7) vary according to the value of
the "Starting word number" allocated to the unit.
