OPERATION
( ) The parenthetical brackets are used to separate CNC program commands from
user comments. They must always be entered as a pair and may or may not
have additional characters separating them. Any time an invalid line of code is
received through the RS-232 port while receiving a program, it is added to the
program between these two brackets.
/ The right slash is used as a block delete flag. If this symbol is the first symbol
in a block and a BLOCK DELETE is enabled, then that block is ignored at run
time. The symbol is also used for division in macro expressions.
In some FANUC compatible controls, the block delete symbol can be used to
choose between two options when the "/" symbol is not at the beginning of the
line. For instance, in the following line, T2 is executed when the block delete
option is off, and when the block delete option is on, T1 is executed.
T1 / T2;
N1 G54
This cannot be done on a HAAS control.
A coding method for acheiving the same results on a HAAS control is given
below:
/ T2 M99 (T2 executed when block delete is off)
T1 (T1 executed when block delete is on)
N1 G54
[ and ] Square brackets are used in macro expressions and functions.
MODE KEYS: The mode keys are in the upper right part of the control panel. These keys change the
operational state of the CNC machine tool. There are six major operation modes. The
user can enter a specific mode by pressing the desired îš“arrowîš” shaped key on the left.
The keys in the same row as the pressed mode key are then made available to the user.
Otherwise, these keys are not available. The current mode is always displayed on the
top line just to the right of the current display on the video screen.
EDIT Selects edit mode.
INSERT Inserts the text in the input buffer after the current cursor location.Also used to
copy blocks of code in a program.
ALTER Changes the item that the cursor is on to the text in the input buffer.
Places an MDI program in the program list.
DELETE Deletes the item that the cursor is on.
UNDO Backs out or undoes up to the last 9 edit changes.
MEM Selects MEM mode.
SINGLE Turns single block on so that when the cycle start button is pressed,
BLOCK only one block of the program running is executed.
