Description of function
Rotation is a modal function that is effective as soon as it has been
defined in the NC program.
The control rotates machining in the working plane about the active
workpiece datum.
The control rotates the input coordinate system (I-CS) as follows:
Based on the angle reference axis, i.e. the main axis
About the tool axis

Page 87
A rotation can be programmed as follows:
Absolute, relative to the positive main axis
Incremental, relative to the last active rotation
If rotation is active, the control displays it on the TRANS tab of the
additional status display.
