Ex.
When the buffer memory address of "[Da.9] Dwell time/JUMP destination positioning data No." of the positioning data No.1 of
axis 2 is determined
6000 + (1000  (2 - 1)) + 10  (1 - 1) + 2 = 7002
Block start data
Block start data consists of five start blocks from Start block 0 to 4, and the block start data of 1 to 50 points is assigned to
each block. The start blocks are assigned to each axis. Block start data has the following structure.

When setting block start data using a program, determine buffer memory addresses using the following calculation formula
and set the addresses.

Appendix 2 How to Determine Buffer Memory Addresses
●Up to 50 block start data points can be
set (stored) for each axis in the buffer
memory addresses shown on the left.
●Items in a single unit of block start
data are shown included in a bold frame.
●Each axis has five start blocks (block Nos. 0 to 4).
