Working area limitation group 2
In the second working area limitation group the axes in the WKS coordinate system can be
limited:
X axis in the plus direction: 10 mm
X axis in the minus direction: No limitation
Y axis in the plus direction: 34 mm
Y axis in the minus direction: -25 mm
Z axis in the plus direction: No limitation
Z axis in the minus direction: -600 mm
A axis in the plus direction: No limitation
A axis in the minus direction: No limitation
The system variables are assigned as follows:
N51 $AC_WORKAREA_CS_COORD_SYSTEM[2] = 1
; The working area limitation of
working area limitation group 2
applies in the WCS.
N60 $AC_WORKAREA_CS_PLUS_ENABLE[2,X] = TRUE
N61 $AC_WORKAREA_CS_LIMIT_PLUS[2,X] = 10
N62 $AC_WORKAREA_CS_MINUS_ENABLE[2,X] = FALSE
N70 $AC_WORKAREA_CS_PLUS_ENABLE[2,Y] = TRUE
N73 $AC_WORKAREA_CS_LIMIT_PLUS[2,Y] = 34
N72 $AC_WORKAREA_CS_MINUS_ENABLE[2,Y] = TRUE
