An alarm will occur when scaling is used for an axis that has scaling
turned off for the parameter.
An alarm will occur when circle cutting is specified while a different
scaling ratio is set for each axis.
Setting a different scaling ratio for each axis in circular interpolation
mode does not result in elliptical interpolation.
When a different scaling ratio is set for each axis and the radius (R) of
the arc is specified in circular interpolation mode, the larger scaling
factor of the axes forming the plane on which the arc is drawn is applied
to the radius.
E.g.) Arc using command "R": The left and right command formats are equivalent.

When a different scaling ratio is set for each axis and the center (I, J) of
the arc is specified in circular interpolation mode, the distance from the
start point to the center (I, J) is not subject to scaling.
E.g.) Arc using commands "I" "J": The left and right command formats are
equivalent.
