Basic offset
The basic offset describes the coordinate transformation between BCS and BZS. It can be used, for example, to
define the palette window zero.
The basic offset comprises:
• Zero offset external
• DRF offset
• Superimposed motion
• Chained system frames
• Chained basic frames
Figure 10-18 Example of the use of the basic offset
The following settings apply:
• The user can change the basic offset from the part program by means of an operator action and from the
PLC.
• If the basic offset is to take effect immediately, an ASUB can be started via the PLC using FC9 in order to
execute the appropriate G code.
Note
Recommendation to the machine manufacturer
Use the 3rd basic offset onwards for your own applications.
The 1st and 2nd basic offset are reserved for PRESET and the "Zero offset external".
