(The buffer memory addresses shown are those of the "positioning data No. 1".)
• Guide to buffer memory address
In the buffer memory address, "n" in "6001+1000n", 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
6001+1000n (
Da.10
M code)
=6001+1000 15=21001
6009+1000n (
Da.7
Arc address
)= 6009+1000 15=21009
(Note-2): The range from axis No.1 to 2 (n=0 to 1) is valid in the QD77MS2.
(Note-3): The range from axis No.1 to 4 (n=0 to 3) is valid in the QD77MS4
