Axis of the third control area direction (EXCUR) must not be used for the definition of the base plane.
Description | A work or protection area of the work area control function (see [FCT-C14// Definition of work and protection areas]) is defined by a base plane (polygon or circle) and an excursion EXCUR in the 3rd dimension. The axis defining the third excursion direction of the control area may not be part of the base plane definition:

Example with error:

#CONTROL AREA BEGIN [ID1 PROT POLY MIN_EXCUR=0 MAX_EXCUR=360 EXCUR_AX=X]

G01 F1000 G90

X0 Y0 (Error 120734)

X0 Y100

#CONTROL AREA END

Corrected example:

#CONTROL AREA BEGIN [ID1 PROT POLY MIN_EXCUR=0 MAX_EXCUR=360 EXCUR_AX=Z]

G01 F1000 G90
