5.2 List of parameters
The setting items of the setting data are explained in this section.
• Guide to buffer memory address
In the buffer memory address, "n" in "1+150n", 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
1+150n ([Pr.4] Unit magnification (AM)) = 1+150 15 = 2251
