11. PROGRAM COMMAND
997
A programmed figure can be magnified or reduced (scaling).
The dimensions specified with X_, Y_, and Z_ can each be scaled up or
down with the same or different rates of magnification.
The magnification rate can be specified in the program.
Unless specified in the program, the magnification rate specified in the
parameter is applied.
Least input increment of scaling magnification is: 0.001 or 0.00001.
It depends on parameter SCR (No. 5400#07) which value is selected.
Specify an axis to be subjected to scaling, using parameter SCLx (bit 0
of parameter No. 5401).
If scaling P is not specified on the block of scaling (G51X_Y_Z_P_ ;), the
scaling magnification set to parameter (No. 5411) is applicable.
If X,Y,Z are omitted, the tool position where the G51 command was
specified serves as the scaling center.
