28-48
Unlike non-modal macro calls, the G66 macro call repeats automatically
after any axis move until cancelled by a G67 block. This also applies to
nested macros. When the control begins execution of the nested macro
1002 in the program below, each axis move in the nested macro also calls
for the execution of the macro 1001.
Example 28.18
Modal Macro Call
N0100G66P1001;
N0200G65P1002;
In Example 28.18, after the complete execution of the macro 1002, the
macro 1001 is called. Any motion blocks in macro 1002 will cause macro
1001 to be executed.

Parameter #1 is set at 1.1 in macro 1001.
X Axis is moved 1 unit and then macro 1001 is called and
executed 2 times.
Z Axis is moved .25 units and then macro 1001 is called and
executed 2 times.
Parameter #1 is set at 2. in macro
1002.
X axis is moved 1 unit then macro 1002 is called and
executed once.
Macro 1002 is canceled.
Macro 1001 is canceled.

N210#1=1.7
N220M99;
Z Axis moves an amount equal to the current value for
parameter #1
Parameter #1 for macro 1001 is set at 1.7.
Macro end.
(MACRO);
O1002;
N300Z#1;
N310M99;
Z Axis moves an amount equal to the current value set
parameter #1 (in this case always 2 units). Macro 1001 is
called and executed twice.
Macro end.
