This display shows a list of the macro variables and their present values. As the control interprets a macro
program, the changes within a macro variable will be displayed on this page and the results can be viewed.
The variables may be modified in this display. For more information on this display, refer to the “Macros”
section of your operator manual.
D Number to serialize with in a G47 - Macro Variable 599 is the one that is used to change the number to
engrave to serialize with, when using a G47 to engrave serial numbers on a part. Every time a G47 P1 (####) is
executed on a Haas mill.

This display allows the operator to activate or deactivate a series of countdown timers for a series of 10 different
maintenance checks, defined in number of hours (see Maintenance section of Operator Manual). To either
activate or deactivate a timer, cursor onto TIME and press ORIGIN. To adjust number of hours, use the right or
left cursor arrow

This display shows the time the tool has been in a feed move (Feed-Time), the actual time the tool has been in
the spindle (Total-Time), and the number of times the tool has been selected (Usage). This information can be
used to assist in predicting tool life.
This display may also be used to generate an alarm when a tool has been used a specific number of times.
The last column is labeled “Alarm,” and if the number is not at zero, an alarm will be generated when that
number count is the same, or above, the Usage number. Alarm 362 TOOL USAGE ALARM is generated when
the count is reached, and may be cleared with RESET. The ALARM numbers can be changed by the operator.
The values in this display can be zeroed by Cursoring onto the specific number that needs to be zero and
pressing ORIGIN. You can zero the whole column by cursoring to the top, onto the actual title, and pressing
ORIGIN to zero all of the data in that column.
The tool that is currently in the spindle will be highlighted on the far left column.

With the tool load display, the operator can enter the maximum load that you can limit for each tool. When this
load is exceeded in a feed move, a certain machine action will be taken. This display shows the SPINDLE
LOAD MAX%, which is the maximum load a tool has ever reached. And the spindle load LIMIT% is what you
need to adjust for the load LIMIT% on each tool.
The tool load monitor operates whenever the machine is in a feed operation (G01, G02, or G03). The values
entered into the tool load LIMIT% display are checked against the actual spindle motor load. If the limit is
exceeded, the tool overload action specified in Setting 84 (Alarm, Feedhold, beep, or Autofeed) will be taken. If
you select Alarm, it’ll stop everything and give you an alarm 174 “Tool Load Exceeded,” This alarm will stop the
axis motors, the spindle motor, turns off the coolant, and disable the servos. With selecting FEEDHOLD,
everything will continue running, but it’ll stop the machine as if pressing feedhold, so you can adjust your
overrides slower, and press cycle start to continue on until the load limit is reached again. With selecting
BEEP, if the load limit is reached, everything will continue running, the control will just start beeping to indicate
the tool has reached its load limit.
