Protection Window; Orientation - Siemens SINUMERIK 840D sl Function Manual

Note
Machine data change
Machine data $MN_...OFFSET[<axis pair>] may only be made changed for an axis pair, if the
function for the axis pair is not active ($MN_...PAIRS[<axis pair>] = 0).
21.3.6

Protection window

Using the machine data, the minimum clearance is defined, which the axes of an axis pair
must not fall below:
MD61519 $MN_CC_PROTECT_WINDOW[<axis pair>] = <minimum clearance>
The axes are braked, if the axis clearance approaches the minimum clearance.
For instance, in the part program, the protection window can be dynamically expanded
(Page 750).
Note
Machine data change
A change to machine data $MN_...WINDOW[<axis pair>] may also be activated when the
($MN_...PAIRS[<axis pair>] ≠ 0) function is activated.
21.3.7

Orientation

The orientation of the axes of the axis pair to one another is specified in the following machine
data:
MD61532 $MN_CC_PROTECT_DIR_IS_REVERSE[<axis pair>] = <value>
<value> Meaning
Note
Machine data change
A change to machine data item $MN_... DIR_IS_REVERSE[<axis pair>] must only be activated
when the function is inactive ($MN_...PAIRS[n] = 0).
