nate system). This is dependent on which offsets are currently active: programmable,
settable, or no offsets.
Upon program start, G90 is active for all axes and remains active until it is deselected in a
subsequent block by G91 (incremental dimensioning data) (modally active).
Incremental dimensioning G91
With incremental dimensioning, the numerical value of the path information corresponds to
the axis path to be traversed. The leading sign indicates the traversing direction.
G91 applies to all axes and can be deselected in a subsequent block by G90 (absolute di-
mensioning).
Specification with =AC(...), =IC(...)
After the end point coordinate, write an equality sign. The value must be put in round brack-
ets.
Absolute dimensioning is also possible for center points using =AC(...). Otherwise, the refer-
ence point for the circle center is the circle starting point.
Programming example

N20 X75 Z=IC(-32)

Functionality
If workpiece dimensions that deviate from the base system settings of the control are present
(inch or mm), the dimensions can be entered directly in the program. The required conver-
sion into the base system is performed by the control system.
