Detailed description

2.2 Enabling/disabling of protection

Protection window
The protection window is recorded in the machine data:
MD61519 $MN_CC_PROTECT_WINDOW[n]
2.2 Enabling/disabling of protection
Enabling/disabling
The protection is active:
• as soon as a valid axis pair is defined in the machine data:
• both axes are referred.
If the two axes are already inside the protection window at the turn-on time, then the
operator must move the axes freely. The software does not prevent any colliding movement
in this condition!
The function is deactivated by deleting the axis pair definition in MD61516
Status display
As mentioned in the beginning, this compile cycle would handle this "global resource" very
sparingly. The operator can therefore determine whether or not he wants to have a status
display of the pairs.
_PROTECT_STATUS
If the control detects the NCK-GUD "_PROTECT_STATUS[n]" at the time of the ramp-up,
then the current status of each pair is recorded in it:
Value
0
1
2
4
