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
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
N73 $AC_WORKAREA_CS_LIMIT_MINUS[2,Y] = –25
N80 $AC_WORKAREA_CS_PLUS_ENABLE[2,Z] = FALSE
N82 $AC_WORKAREA_CS_MINUS_ENABLE[2,Z] = TRUE
