Coordinate transformation via frame variables

In addition to frame instructions (Page 307), such as e.g. ROT, AROT, SCALE, etc., the
workpiece coordinate system (WCS) can also be transformed using frame variables $P_...FR
(data management frames) and $P_...FRAME (active frames).
The following diagram provides an overview of structuring frame variables:
● Data management frames
● Active frames
● Active total frame: Chain of all active frames
● NCU global frames
● Channel-specific frames
