Coordinate transformations (frames)

12.1

Frames

Frame
The frame is a self-contained arithmetic rule that transforms one Cartesian coordinate system
into another Cartesian coordinate system.
Basic frame (basic offset)
The basic frame describes coordinate transformation from the basic coordinate system (BCS)
to the basic zero system (BZS) and has the same effect as settable frames.
See Basic coordinate system (BCS) [Page 28].
Settable frames
Settable frames are the configurable work offsets which can be called from within any NC
program with the G54 to G57 and G505 to G599 commands. The offset values are predefined
by the user and stored in the zero offset memory on the control. They are used to define the
settable zero system (SZS).
See:
• Settable zero system (SZS) [Page 31]
• Settable work offset (G54 to G57, G505 to G599, G53, G500, SUPA, G153) [Page 159]
