• Working area limits for all channel axes
• A reference system, i.e. the coordinate system on which the working area limitations are based
The number of the working area limitation groups used is set in the machine data:
MD28600 $MC_MM_NUM_WORKAREA_CS_GROUPS
Working area limits
Both the activation of the working area limitation and the working area limits for the individual channel axes are
defined by the following channel-specific system variables:
The definition is given by writing the system variables through the user interface or in the part program.
Selection of the reference system
The reference system for the group's working area limitations is selected by means of the channel-specific
system variable:
$P_WORKAREA_CS_COORD_SYSTEM [<GN>] = <value>
System variable
Meaning
$P_WORKAREA_CS_PLUS_ENABLE[<GN>, <AN>]
Activation of working area limitation in a positive traversing
direction for axis <AN> in group <GN>
$P_WORKAREA_CS_LIMIT_PLUS[<GN>, <AN>]
Limit value in a positive traversing direction for axis <AN> in
group <GN>
Only effective if:
..._PLUS_ENABLE[<GN>, <AN>] = TRUE
$P_WORKAREA_CS_MINUS_ENABLE[<GN>, <AN>]
Activation of working area limitation in a negative traversing
direction for axis <AN> in group <GN>
$P_WORKAREA_CS_LIMIT_MINUS[<GN>, <AN>]
Limit value in a negative traversing direction for axis <AN> in
group <GN>
Only effective if:
..._MINUS_ENABLE[<GN>, <AN>] = TRUE
Parameters
<GN>
Number of the working area limitation group
<AN>
Channel axis name
<value>
Meaning
1
Working area limitation based on the workpiece coordinate system
3
Working area limitation based on the AZS
