particular number. For example,

G65 A2.12 B3.213 J36.9 J–12 E129.73 P2200

variable #1=2.12 #2=3.213 #5=36.9 #8=–12 #8= ERROR

In the above example, variable #8 has already been assigned a value by the second address J (value, -12), since the value of address E is also assigned to variable #8, the control returns error message 3064 BAD MACRO STATEMENT.

A decimal point and a sign can also be transferred at the addresses.

20.2 The Modal Macro Call

20.2.1 Macro Modal Call in Every Motion Command (G66)

As a result of instruction

G66 P(program number) L(number of repetitions) <argument assignment>

the macro body specified at address P (program number) will be called after the execution of each motion command, as many times as is the number specified at address L. The interpretations of addresses P and L and the rules of argument assignment are identical with those described for instruction G65.

The selected macro will be called until with command

G67

it is canceled.

For example, a hole has to be drilled in a given segment of the part program after each movement:

Main program

...

G66 P1250 Z–100 R–1 X2 F130 (Z=Z point of hole, R=R point of hole, X=dwell F=feed)

G91 G0 X100

drilling is performed after each posi- tioning

(rapid-traverse positioning in direction Z to the point specified at address R–1)

(drilling as far as the point Z specified at address Z–100, with the feed specified at address F130)

(dwell at the bottom of the hole for the time specified at address X2)
