specified in $MN_...PAIRS[n] must not undershoot. Parameters are assigned for the
protection window in the following item of machine data:
MD61519 $MN_CC_PROTECT_WINDOW[n] = <minimum distance>
Note
Machine data change
A change to machine data item $MN_...WINDOW[n] may also be activated when the
protection function is active ($MN_...PAIRS[n] ≠ 0).

Orientation

The orientation of the machine axes to one another is specified in the following item of
machine data:
MD61532 $MN_CC_PROTECT_DIR_IS_REVERSE[n] = <orientation>

Protection window extension

The protection window for which parameters are assigned in $MN_...WINDOW[n] can be
expanded using the protection window extension function. The protection window extension
is set in the following item of machine data:
MD61533 $MN_CC_PROTECT_WINDOW_EXTENSION[n] = <extension>
The resulting effective protection window is as follows:
• Effective protection window[n] = protection window $MN_...WINDOW[n] + protection
window extension $MN_...WINDOW_EXTENSION[n]
Note
