Detailed Description
2.3 Monitoring of static limits
Effect
Automatic operating modes
1. With / without transformation
2. With overlaid motion
Manual operating modes
1. JOG with / without transformation
General
• Activation of the working area limitation
• Overrunning of the working area limitation in JOG mode
2-28
The part program block with a programmed traversing motion that would lead to
overrunning of the working area limitation is not started.
The part program block with a programmed traversing motion that would lead to
overrunning of the working area limitation is started. Axes that are traversed with overlaid
motion stop at the working area limitation.
The axis is positioned at the working area limitation and then stopped. Other machine
axes participating in the traversing motion are braked. The preset path is left during this
process.
If the actual position of an axis after activation is located outside of the working area
limitation, it is stopped with the maximum permissible acceleration.
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:
Alarm: "10631 Channel <Channel number> Axis <Axis identifier> is at the working area
limitation <Direction>"
