\layout Standard

The format of a parameter file is shown in Table 
\begin_inset LatexCommand \ref{cap:Parameter-File-Format}

\end_inset 

.
 The file consists of any number of header lines, followed by one blank
 line, followed by any number of lines of data.
 The Interpreter skips over the header lines.
 It is important that there be exactly one blank line (with no spaces or
 tabs, even) before the data.
 The header line shown in Table 
\begin_inset LatexCommand \ref{cap:Parameter-File-Format}

\end_inset 

 describes the data columns, so it is suggested (but not required) that
 that line always be included in the header.
\layout Standard

The Interpreter reads only the first two columns of the table.
 The third column, 
\begin_inset Quotes eld
\end_inset 

Comment,
\begin_inset Quotes erd
\end_inset 

 is not read by the Interpreter.
\layout Standard

Each line of the file contains the index number of a parameter in the first
 column and the value to which that parameter should be set in the second
 column.
 The value is represented as a double-precision floating point number inside
 the Interpreter, but a decimal point is not required in the file.
 All of the parameters shown in Table 
\begin_inset LatexCommand \ref{cap:Parameter-File-Format}

\end_inset 

 are required parameters and must be included in any parameter file, except
 that any parameter representing a rotational axis value for an unused axis
 may be omitted.
 An error will be signalled if any required parameter is missing.
 A parameter file may include any other parameter, as long as its number
 is in the range 1 to 5400.
 The parameter numbers must be arranged in ascending order.
 An error will be signalled if not.
 Any parameter included in the file read by the Interpreter will be included
 in the file it writes as it exits.
 The original file is saved as a backup file when the new file is written.
 Comments are not preserved when the file is written.

\begin_inset LatexCommand \label{sub:Coordinate-Systems}

\end_inset 


\layout Standard

In the RS274/NGC language view, a machining center has an absolute coordinate
 system and nine program coordinate systems.
\layout Standard

You can set the offsets of the nine program coordinate systems using 
\family typewriter 
G10 L2 Pn
\family default 
 (n is the number of the coordinate system) with values for the axes in
 terms of the absolute coordinate system.
 See Section 
\begin_inset LatexCommand \ref{sub:G10:-Set-Coordinate}

\end_inset 

.
\layout Standard

You can select one of the nine systems by using 
\family typewriter 
G54
\family default 
, 
\family typewriter 
G55
\family default 
, 
\family typewriter 
G56
\family default 
, 
\family typewriter 
G57
\family default 
, 
\family typewriter 
G58
\family default 
, 
\family typewriter 
G59
\family default 
, 
\family typewriter 
G59.1
\family default 
, 
\family typewriter 
G59.2
\family default 
, or 
\family typewriter 
G59.3
\family default 
 (see Section 
\begin_inset LatexCommand \ref{sub:G54-to-G59.3:}

\end_inset 

).
 It is not possible to select the absolute coordinate system directly.
\layout Standard

You can offset the current coordinate system using 
\family typewriter 
G92
\family default 
 or 
\family typewriter 
G92.3
\family default 
.
 This offset will then apply to all nine program coordinate systems.
 This offset may be cancelled with 
\family typewriter 
G92.1
\family default 
 or 
\family typewriter 
G92.2
\family default 
.
 See Section 
\begin_inset LatexCommand \ref{sub:G92,-G92.1,-G92.2,}

\end_inset 

.
\layout Standard

You can make straight moves in the absolute machine coordinate system by
 using 
\family typewriter 
G53
\family default 
 with either 
\family typewriter 
G0
\family default 
 or 
\family typewriter 
G1
\family default 
.
 See Section 
\begin_inset LatexCommand \ref{sub:G53:-Move-in}

\end_inset 

.
\layout Standard

Data for coordinate systems is stored in parameters.
\layout Standard

During initialization, the coordinate system is selected that is specified
 by parameter 5220.
 A value of 1 means the first coordinate system (the one 
\family typewriter 
G54
\family default 
 activates), a value of 2 means the second coordinate system (the one 
\family typewriter 
G55
\family default 
 activates), and so on.
 It is an error for the value of parameter 5220 to be anything but a whole
 number between one and nine.
