Definition of control areas
The definition of a work or protection area has to be done directly in NC program. The definition consists of #-commands and a sequence of standard movement blocks. The standard movement blocks must be programmed in absolute dimensions. The contour of the control area in the plane is defined either with a closed polygon formed by linear movement blocks (end point and starting point of the block sequence must be identical) or by a full circle. The excursion in the third dimension and further characteristics of the control area are defined in the assigned #-command.
Start of definition of a control area:
#CONTROL AREA START [ ID <expr> WORK | PROTPOLY | CIRC MIN_EXCUR <expr> MAX_EXCUR <expr> ] (modal)
ID<expr>
WORK Control area is a work space.
PROT Control area is a protection space.
POLY Contour of control area is defined as a closed polygonal shape.
CIRC Contour of control area is defined as a full circle.
MIN_EXCUR<expr> Limitation of the control area in the third dimension in negative direction.
MAX_EXCUR<expr> Limitation of the control area in the third dimension in positive direction.
End of definition of a control area:
#CONTROL AREA END (modal)
Each control area has to be closed with the command #CONTROL AREA END. Only after that further control areas can be defined.
 | A deselected control area can be redefined by programming the new definition using the same ID. |
