5.4 List of block start data
The illustrations below show the organization of the block start data stored in the buffer
memory of Simple Motion module. The block start data setting items [Da.11]
to [Da.14]
are explained in the pages that follow.

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).
Start block 2 to 4 are not allocated to buffer
memory.
Set with GX Works2.
(Note): For information on the organization
of the buffer memory addresses
assigned to the start block 1, refer
to Appendix 1 "List of buffer memory
addresses".
The following pages explain the block start data setting items [Da.11] to [Da.14].
(The buffer memory addresses shown are those of the "1st point block start data (block
No. 7000)".)
• Guide to buffer memory address
In the buffer memory address, "n" in "22000+400n", etc. indicates a value
corresponding to axis No. such as the following table.
Axis No. n Axis No. n Axis No. n Axis No. n
1 0 5 4 9 8 13 12
2 1 6 5 10 9 14 13
3 2 7 6 11 10 15 14
4 3 8 7 12 11 16 15
(Note-1): Calculate as follows for the buffer memory address corresponding to each axis.
(Example) For axis No. 16
22000+400n ([Da.11] Shape) = 22000+400 15 = 28000
