Basic Functions
100 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Manual operating modes
• JOG with / without transformation
The axis is positioned at the working area limitation and then stopped.
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>
2.2.7.2 Working area limitation in BKS
Application
Using the "working area limitation in BKS", 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 instructions:
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:
<value> Meaning
0 The working area limitation is deactivated during the geometry axis change.
1 The working area limitation remains activated during the geometry axis change.
