The two Light Emitting Diode (LED) front panel displays tell you what is going on inside the controller. There are
nine characters that are displayed on each. The left two characters are the step number and go from 1 to 99.
They cannot be changed with the numeric keys and are selected by using the STEP SCAN arrow buttons. The
remaining seven characters display data that is stored in memory. Every step (or block) contains several
pieces of information that are necessary for your program, but they cannot be displayed simultaneously. In
order to overcome this, use the DISPLAY SCAN button to view the pieces of data for each step. The data is
preceded by a letter to indicate which piece of information is being displayed. For example, if an
F
precedes
the number, the displayed data is for feed rates. There are five such registers. They are:
1) current spindle position (indicated by a letter
P
)
2) step size and direction (indicated by no letters),
3) feed rate (indicated by a letter
F
),
4) loop count (indicated by a letter
L
)
5) G code (indicated by a letter
G
)
Successive pushes of the
right
arrow button will cause the display to cycle to the next register, that is,
POSITION - STEP SIZE - FEED RATE - LOOP COUNT - G CODE - POSITION - etc. In RUN mode, the
right
arrow button can select among any of these five displays. In PROGRAM mode, all of these but the position
may be displayed.
Refer to the diagram on the following page. When you are in the PROGRAM mode, you are editing the num-
bers (or registers) inside the dotted lines. Think of the LED displays as a window that allows you to see only
one number of the program at a time. The DISPLAY SCAN button allows you to scan sideways and see all the
information for a single step. Pushing the DISPLAY SCAN button shifts the window one place to the right,
looping from left to right at the end of the row. Pushing the
up
arrow allows you to view the previous step, while
pushing the
down
arrow allows you to view the next step. Using these three keys, you can scan to anywhere
in the program. If you enter a new number in that position, the number will be stored when you scan to another
position or return to RUN mode.
