11. PROGRAM COMMAND
1485
A programmed figure can be magnified or reduced (scaling).
The dimensions specified with X_, Y_, and Z_ can each be magnified or
reduced with the same or different rates of magnification.
The magnification rate can be specified in the program or by a parameter.
Least input increment of scaling magnification is: 0.001 or 0.00001 and
is set by parameter SCR (No. 5400#07).
The scaled axis is selected by parameter SCLx (bit 0 of parameter No.
5401).
The value in the scaling magnification parameter (No. 5411) is used when
not defined in the program.
If X,Y,Z are omitted, the tool position where the G51 command was
specified serves as the scaling center.
