11.10 SCALING
General
A programmed figure can be magnified or reduced (scaling).
Two types of scaling are supported. One type applies the same rate of
magnification to all axes (X, Y, and Z). The other type applies a
different rate of magnification to each axis.
Unless specified in the program, the magnification rate specified in the
parameter is applied.
- Scaling along all axes at the same rate of magnification
Set bit 4 (XSC) of parameter No. 7611 to 0. If scaling magnification
rate P is not specified, the magnification specified in parameter No.
6410 is assumed
Scaling up or down along all axes at the same rate of magnification
