PROGRAM D ISPLAYS
The PROGRAM DISPLAY is used to show a program being edited in EDIT mode or a program being run in
MEM. In MEM mode, there is also a PROGRAM REVIEW display available.
The PROGRAM DISPLAY uses 18 lines of the text display area of the CRT to show the command blocks of a
CNC program. The display is 40 positions wide and blocks that are longer than 40 positions are continued on
the next line of the display.
The PROGRAM REVIEW function is available whenever a program is being run. This allows you to review the
program that is running. This is selected by pressing F4 while in MEM mode and PROGRAM DISPLAY. The
screen is changed to an 80 column display with the normal MEM display on the left and PROGRAM REVIEW
on the right. The CURSOR and PAGE UP and PAGE DOWN keys can be used to change the display on the
right to a different part of the program. The display on the left will show the progress of the running program.
To exit PROGRAM REVIEW, select any other display.
While you are running a program, the BACKGROUND EDIT function is available as a standard feature. BACK-
GROUND EDIT allows you to edit any named program in memory while any program is being run in memory.
BACKGROUND EDIT is selected from MEM mode in PROG display by entering Onnnnn with the program
number and pressing F4. The display will change to the selected program while still running the first program.
BACKGROUND EDIT is enabled by parameters in your machine.
POSITION D ISPLAYS
The following are the five position displays in this control:
Home Page
This display shows the four displays simultaneously in small characters. The other displays are shown in large
characters. The PAGE UP and PAGE DOWN keys will change displays. The coordinates displayed (operator,
work, machine, or distance to go) are selected using the cursor up and down keys. The last display selected
will be shown in CURNT COMDS and SETNG / GRAPH displays when they are selected. In this display, any
axis that is at the zero position will be highlighted. In the other four displays, the selected axis will be blinking.
Operator Display
This display is for the operator/setup person to use as desired, and is not used by the control for any position-
ing functions. In JOG mode, and with this display selected, the ORIGIN button can be used to set the zero
position. This display will then show position relative to the selected zero position.
Work Display
This display shows how far the tool is away from the X, Y and Z zero of the programmed part. On power up, it
will display the value in work offset G54 automatically. It can only be changed by G54 through G59, G110
through G129, or by a G92 command. The machine uses this coordinate system to run the part.
Machine Display
This display is the machine coordinate system that is automatically set on power up and the first ZERO RET.
It cannot be changed by the operator or any work coordinate systems, and will always show the distance from
machine zero. It can be used by a non-modal G53 command.
Distance To Go
This display is an incremental display that shows the travel distance remaining before the axes stop. When in
the ZERO RET mode, this display shows a diagnostic value. When in JOG mode, this display shows the total
distance jogged. In rigid tapping, this number decreases to zero at the bottom of the hole and then increases
again as the reverse stroke occurs.
