Syntax – General Guidelines Guideline Topic Guideline Examples
Command Delimiters
(<cr> and <lf>)
All commands must be separated
by a delimiter. A carriage return is
the most commonly used.
Neutral Characters
(<sp>)
Using neutral characters
anywhere within a command will
not affect the command.
Set velocity limit to 100 rps:
DMVLIM<sp>1ØØ<cr>
Case Sensitivity There is no case sensitivity. Use
upper or lower case letters within
commands.
Initiate motion:
GO1
go1
Comment Delimiter
[semi-colon ( ; ) or
apostrophe ( ‘ )]
All text between a comment
delimiter and a command delimiter
is considered program comments.
Add a comment to the command:
DMVLIM<sp> ; set
velocity
; limit
Binary and
Hexadecimal Values
When making assignments with or
comparisons against binary or
hexadecimal values, you must
precede the binary value with the
letter “b” or “B”, and the hex value
with “h” or “H”. In the binary
syntax, an “x” simply means the
status of that bit is ignored.
Binary:
ERRORL = bØ1111x11111111111
Hexadecimal:
ERRORL = h7FxF
Note: The command line is limited to 32 characters (including spaces).
