A scaling magnification can be set for each axis or for all axes in common.
A parameter can specify whether it should be set for each axis or for all
axes.
X_Y_ : Absolute command of
center coordinate value of
scaling
I_J_ : Magnification of scaling
of X axis and Y axis
(Unit 0.001 or 0.00001 is
selected according to
the parameter.)
The magnification which can be
instructed is as follows.
"0.0001–"9.99999 or
"0.001–"9. 999
