Function
In addition to the programming options already described in the Programming Guide
"Fundamentals", you can also define coordinate systems with predefined frame variables.
The following coordinate systems are defined:
MCS: Machine coordinate system
BCS: Basic coordinate system
BZS: Basic origin system
SZS: Settable zero system
WCS: Workpiece coordinate system
What is a predefined frame variable?
Predefined frame variables are keywords whose use and effect are already defined in the
control language and that can be processed in the NC program.
