(4) Program example
(a) The Motion SFC program to read M-codes is shown as the following
conditions.
1) Axis used No. .......................................................... Axis 3
2) Processing at the positioning start by M-code ....... M-code No. is output
3) Processing at the positioning completion by M-code
a) M-code = 3 ..................................................... Y120 turns on
b) M-code = 5 ..................................................... Y121 turns on
c) M-code is except for (3 or 5) ......................... Y122 turns on
(b) Motion SFC program with the above conditions are shown below.
