Define the working area limitation groups
Additionally two working area limitation groups will be defined:
Working area limitation group 1
In the first working area limitation group the axes in the SZS coordinate system will be limited:
● X axis in the plus direction: 10 mm
● X axis in the minus direction: No limitation
● Y axis in the plus direction: No limitation
● Y axis in the minus direction: 25 mm
● Z axis in the plus direction: No limitation
● Z axis in the minus direction: No limitation
● A axis in the plus direction: 10 degrees
● A axis in the minus direction: -40 degrees
The system variables are assigned as follows:
Program code
N1 $P_WORKAREA_CS_COORD_SYSTEM[1]=3
N10 $P_WORKAREA_CS_PLUS_ENABLE[1,X]=TRUE
N11 $P_WORKAREA_CS_LIMIT_PLUS[1,X]=10
N12 $P_WORKAREA_CS_MINUS_ENABLE[1,X]=FALSE
N20 $P_WORKAREA_CS_PLUS_ENABLE[1,Y]=FALSE
N22 $P_WORKAREA_CS_MINUS_ENABLE[1,Y]=TRUE
N23 $P_WORKAREA_CS_LIMIT_MINUS[1,Y]=25
N30 $P_WORKAREA_CS_PLUS_ENABLE[1,Z]=FALSE
N32 $P_WORKAREA_CS_MINUS_ENABLE[1,Z]=FALSE
N40 $P_WORKAREA_CS_PLUS_ENABLE[1,A]=TRUE
N41 $P_WORKAREA_CS_LIMIT_PLUS[1,A]=10
N42 $P_WORKAREA_CS_MINUS_ENABLE[1,A]=TRUE
N43 $P_WORKAREA_CS_LIMIT_MINUS[1,A]=-40
Working area limitation group 2
In the second working area limitation group the axes in the WCS 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
