ADTECH9 Series CNC Programming Manual
Between G66 and G67, after the segment with motion instruction is executed, all the specified macro
subroutines are called and executed, and the execution times are specified by L.
Format:
G66 P_ L_ <argument>;
P_ :subroutine No.
L_ :repeat times
Details:
After G66 instruction is specified and before G67 (cancel) instruction is specified, all the segments with
motion instruction will call G66 specified macro subroutine automatically after executed.
G66 and G67 instructions are in the same program, and must be specified in pair. If G66 instruction isn’t
executed first and G67 instruction is executed directly, the system will alarm.
In G66 instruction segment, all the bit addresses are considered as the arguments of G65.

For example: drilling cycle

Note:
G66 instruction executes the subroutine for the first time, and later motion instructions will call the
subroutine automatically.
After G67 instruction takes effect, the subroutine won’t be executed.
