Considerations for some functions.

Work zones.
The work zones may be defined, enabled and disabled from the PLC using the command
CNCWR, writing the corresponding variables.
Variable.
[ch].A.ZONELIMITTOL.xn
[ch].G.ZONEST[k]
[ch].A.ZONELOWLIM[k].xn
[ch].A.ZONEUPLIM[k].xn
[ch].G.ZONECIRAX1[k]
[ch].G.ZONECIRAX2[k]
[ch].G.ZONECIR1[k]
[ch].G.ZONECIR2[k]
[ch].G.ZONER[k]
[ch].G.ZONETOOLWATCH[k]
Syntax of the variables.
·ch· Channel number.
·k· Zone number.
·xn· Name, logic number or index of the axis.
[2].G.ZONEST[1]
A.ZONEUPLIM[1].Z
A.ZONEUPLIM[1].4
[2].A.ZONEUPLIM[1].1
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).
<condition> = MOV 0 R1 = CNCWR(R1, A.ZONELOWLIM[1].X, M1)
= MOV 1000000 R1 = CNCWR(R1, A.ZONEUPLIM[1].X, M1)
= MOV 1 R1 = CNCWR(R1, G.ZONEST[1], M1)
The coordinates will be given in ten-thousandths if they are in mm or hundred-thousandths
if they are in inches.
Meaning.
Safety distance of the limits of the work zones.
Status of work zone [K].
(0=Disabled zone).
(1=Work zone enabled as no-entry).
(2=Work zone enabled as no-exit).
Lower limit of zone [k].
Upper limit of zone [k].
Logic axis corresponding to the first coordinate of the center of
zone [k].
Logic axis corresponding to the second coordinate of the center
of zone [k].
Center coordinate of zone [k] along the first axis that defines the
circular zone.
Center coordinate of zone [k] along the second axis that defines
the circular zone.
Radius of zone [k] (circular zone).
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).
Channel ·2·. Zone 1.
Z axis. Zone 1.
Axis with logic number ·4·. Zone 1.
Axis with index ·1· in the channel ·2·. Zone 1.
