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.
1 0
2 1
3 2
4 3
(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

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".
