Working Area Limitation In Bks - Siemens SINUMERIK 840D sl Function Manual

A3: Axis Monitoring, Protection Zones
3.2 Axis monitoring functions
Powerup response
If an axis moves outside the permissible working area when activating the working area limits,
it will be immediately stopped with the maximum permissible acceleration.
Overrunning of the working area limitation in JOG mode
In JOG mode, an axis is moved to no further than its working area limit by the control system.
When the traverse button is pressed again, an alarm is displayed and the axis does not traverse
any further.
Geo-axis replacement
Through the following machine data it is adjustable, whether during geometry axis change the
active working area limitation is retained or deactivated:
MD10604 $MN_WALIM_GEOAX_CHANGE_MODE = <value>
<value>
0

Working area limitation in BKS

Application
Using the "working area limitation in BCS", the working area of a machine tool is limited so
that the surrounding devices (e.g. tool revolver, measuring stations) are protected against
damage.
Working area limits
The lower and upper working area limits of each axes are adjusted through setting data or
programmed through part program commands:
Working area limitation through setting data
The adjustments are done through the immediately effective axis-specific setting data:
SD43420 $SA_WORKAREA_LIMIT_PLUS (working area limitation plus)
SD43430 $SA_WORKAREA_LIMIT_MINUS (working area limitation minus)
Programmed working area limitation
The programming is done using the G commands:
G25 X... Y... Z...
G26 X... Y... Z...
108
Meaning
The working area limitation is deactivated during the geometry axis change.
The working area limitation remains activated during the geometry axis change.
