ACU-RITE 3500i 389
11.4 Advanced Programming
Modifiers
Use modifiers to alter the way the 3500i interprets a word address. For
example, a single value in an Inch Mode program may be forced to
Metric Mode, without programming G71. Or, arc center values (I, J, or
K) may be forced to an absolute value.
The address and modifier must be accompanied by an ampersand
(&). Place the ampersand (&) between the address word to be
modified and the modifier. The address word is programmed first,
followed by &, followed by the modifier, followed by the value.
The modifier is non-modal and is applied only to the address word it
accompanies.
The following available modifiers are listed.
Example: G02 X2.0 Y1.0 I&A1.5 J&A1.0
The example forces the I and J center of an arc to be in Absolute
Mode. I and J are incremental by default. Assume the axes are
at X1 Y1.
Block Separators
Block separators (;) can be used to place several functions on one line
of a program. This is useful in Manual Data Input (MDI) Mode because
you can combine several commands on one line at the command line.
The number of separate steps in a program is limited only by the
available memory. Block separators can also be used in programs.
Example 1 executes five moves on the machine when you touch
Start. Each move is separated by the (;) block separator.
Example 1: G90 G01 X0 Y0 F30 ; X3 ; Y-2 ; X0 ; Y0
Example 2 moves the axes linearly to X0 Y0, then CW to X1 Y1, then
linearly to X2.
Example 2: G90 G01 X0 Y0 F10 ; G02 X1 Y1 I1 J0 F8 ; G01 X2
Modifier Function
A Force the address word to be in Absolute Mode.
D Force the address word to be in Incremental Mode.
E Force the address word to be in Inch Mode.
M Force the address word to be in Millimeter Mode.
