Function
This parameter determines how the control handles M- and G-codes when
the control executes an end of program command (M02 or M30).

G-codes back to their default values when the control executes an end of
program command. Modal M- and G-codes default back to their power-up
condition, and nonmodal G-codes are reset to their default values.
No -- When this parameter is set as no, the condition of the M- and
G-codes are retained when the control executes an end-of-program
command. All modal M- and G-codes remain at their present value, and
nonmodal M- and G-codes remain at their present value.
