6.2 Frame instructions
Function
For the possible frames the position of one of the target coordinate systems is defined:
• Basic frame (basic offset)
• Settable frames (G54...G599)
• Programmable frames
In addition to these frames, you can program replacing and additive statements or generate
frames as well as frame rotations for tool orientation. Certain set frames or superposed
movements and transformations can also be deselected.
Basic frame (basic offset)
The basic frame describes the coordinate transformation from the Basic Coordinate System
(BCS) to the Basic Zero System (BZS) and has the same effect as for settable frames.
Settable instructions
Settable instructions are the zero offsets, which can be called from any NC program with the
commands G54 to G599. The offset values are predefined by the user and stored in the zero
offset memory on the control. This is used to define the Workpiece Coordinate System
(WCS).
Programmable instructions
Programmable instructions (TRANS, ROT, etc.) are valid in the current NC program and
refer to the settable instructions. The programmable frame is used to define the Workpiece
Coordinate System (WCS).
