10.3 Interface signals Traverse request and Motion enable
drive test
Axes with a mechanical brake may need the brake to be activated in some
cases. For this, select the option Enable with PLC in the basic display of the
traverse function being used.
The request signal generated on selection of the measuring function Traverse
request drive test (DB31.DBX61.0) and acknowledgement signal Motion en-
able drive test (DB31.DBX1.0) can be gated accordingly in the PLC user pro-
gram.
This safety mechanism can be deselected via the “Enable without PLC” option.
The traversing range monitoring function can be deactivated for axes with an
endless traversing range.
