Detailed description
2.1 Axis monitoring
Effects
Automatic operating modes
• With / without transformation
• With overlaid motion
Manual operating modes
• JOG with / without transformation
General
• Activation of the working area limitation
• Overrunning of the working area limitation in JOG mode
• Geo-axis replacement

The part program block with a programmed traversing motion that would lead to
overrunning of the working area limitation is not started.
The axis, which would violate the working area limitation due to the overlaid movement, is
braked without jerk limitation and will come to the position of the working area limitation.
Other axes involved in the movement are braked corresponding to the currently
applicable acceleration. The preset path is left during this process.
The axis is positioned at the working area limitation and then stopped.
If the actual position of an axis after activation is located ouutside of the working area
limitation, it is stopped with the maximum permissible acceleration without jerk limitation.
If the position of the working area limitation is reached and renewed pressing of the
traversing button should cause further travel in this direction, an alarm is displayed and
the axis is not moved farther.
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
= 0: The working area limitation is deactivated during the geometry axis change.
= 1: The working area limitation remains activated during the geometry axis change.
