The traversing movement at a specific point can be described by
S
Reference-measure input (absolute measure input) G90 or
S
Incremental input (relative measure input) G91
You can switch back and forth at will between reference-measure and incre-
mental input.
The status at startup is reference-measure programming G90.
G90 and G91 are modal.
Absolute dimensioning is the method used to specify dimensions that gener-
ally refer to the coordinate system.

Note
To ensure precise reproduction of the program, the first block should contain
reference-measure programming.
Incremental dimensioning is the method used to specify incremental dimen-
sions that refer to the last actual position.
