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
