- Horizontal rotation angle
When the graphic coordinate system selected is a three-dimensional
one, such as 7 (XYZ), 8 (YZX), or 9 (ZXY), the coordinate system can
be rotated about a horizontal plane of rotation. The rotation angle can
be set in the range of -360 deg. to +360 deg..
The initial rotation angle can be set for parameter No. 4831. The actual
rotation angle is equal to the initial rotation angle plus the specified
rotation angle.
In Fig. 10.11 (f), shown below, graphic coordinate system XYZ is
converted into XY"Z" because of the following settings:
Initial rotation angle: 180 deg.
Horizontal rotation angle: 30 deg.
