5 – Cursor Keys
Cursor Keys
The cursor keys are in the center of the control panel. They give the user
the ability to move to and through various screens and fields in the control. They are used
extensively for editing and searching CNC programs. They may be arrows or commands.
Up/Down
– Moves up/down one item, block or field.
Page Up/Down
– Used to change displays or move up/down one page when viewing a program.
HOME
– Will move the cursor to the top-most item on the screen; in editing, this is the top left block of
the program.
END
– Will take you to the bottom-most item of the screen. In editing, this is the last block of the
program.
6 and 7 – Alpha Keys and Numeric Keys
The Alpha Keys allow the user to enter the 26 letters of the alphabet along with some special characters.
Depressing any Alphabet Key automatically puts that character in the Input Section of the control (lower
left-hand corner).
SHIFT
key provides access to the yellow characters shown in the upper left corner of some of
the alphanumeric buttons on the keyboard. Pressing SHIFT and then the desired white
character key will enter that character into the input buffer.
EOB
key enters the end-of-block character, which is displayed as a semicolon on the
screen and signifies the end of a programming block. It also moves the cursor to the
next line.
Parentheses are used to separate CNC program commands from user comments. They must
always be entered as a pair. Example: (T1 ½” End Mill)
Also any time an invalid line of code is received through the RS-232 port, it is added to the
program between parentheses.
(–) and (.)
These keys are used to define negative numbers and give decimal position.
+ = # * [ ]
These symbols are accessed by first pressing the SHIFT key and then the key with
the desired symbol. They are used in macro expressions (Haas option) and in
parenthetical comments within the program.
, ? % $ ! & @ :
These are additional symbols, accessed by pressing the SHIFT key, that can be
used in parenthetical comments.
