4.5 Considerations for some functions.
4.5.1 Work zones.
The work zones may be defined, enabled and disabled from the PLC using the command
CNCWR, writing the corresponding variables.
Syntax of the variables.
·ch· Channel number.
·k· Zone number.
·xn· Name, logic number or index of the axis.
Example of how to activate a work zone from the PLC.
The following example shows how to define a forbidden zone of the X axis the area between
position 0 and 100 mm (1000000 tenth-thousands of a mm).
The coordinates will be given in ten-thousandths if they are in mm or hundred-thousandths
if they are in inches.
Variable. Meaning.
[ch].A.ZONELIMITTOL.xn Safety distance of the limits of the work zones.
[ch].G.ZONEST[k] Status of work zone [K].
(0=Disabled zone).
(1=Work zone enabled as no-entry).
(2=Work zone enabled as no-exit).
[ch].A.ZONELOWLIM[k].xn Lower limit of zone [k].
[ch].A.ZONEUPLIM[k].xn Upper limit of zone [k].
[ch].G.ZONECIRAX1[k] Logic axis corresponding to the first coordinate of the center of
zone [k].
[ch].G.ZONECIRAX2[k] Logic axis corresponding to the second coordinate of the center
of zone [k].
[ch].G.ZONECIR1[k] Center coordinate of zone [k] along the first axis that defines the
circular zone.
[ch].G.ZONECIR2[k] Center coordinate of zone [k] along the second axis that defines
the circular zone.
[ch].G.ZONER[k] Radius of zone [k] (circular zone).
[ch].G.ZONETOOLWATCH[k] Monitor the tool tip or the tool base.
(0=Monitor the tool tip).
(1=Monitor the tool base).
(2=Monitor the tool tip and the tool base).
