Feedback
Once the continuous procedure takes effect, a feedback is sent to the PLC:
● Machine axes:
– DB31, ... DBX65.6 (active machine function "Continuous manual traversing")
● Geometry axes:
– DB21, ... DBX41.6 (geometry axis 1: Active machine function "Continuous manual
– DB21, ... DBX47.6 (geometry axis 2: Active machine function "Continuous manual
– DB21, ... DBX53.6 (geometry axis 3: Active machine function "Continuous manual
● Orientation axes:
– DB21, ... DBX333.6 (orientation axis 1: Active machine function "Continuous manual
– DB21, ... DBX337.6 (orientation axis 2: Active machine function "Continuous manual
– DB21, ... DBX341.6 (orientation axis 3: Active machine function "Continuous manual
Travel command plus/minus
Once a traversing request for an axis is pending, the interface signal "Travel command minus"
or "Travel command plus" is output to the PLC depending on the direction of movement:
● Machine axes:
– DB31, ... DBX64.6 (travel command "minus") or
– DB31, ... DBX64.7 (travel command "plus")
● Geometry axis 1:
– DB21, ... DBX40.6 (geometry axis 1: Travel command "minus") or
– DB21, ... DBX40.7 (geometry axis 1: Travel command "plus")
● Geometry axis 2:
– DB21, ... DBX46.6 (geometry axis 2: Travel command "minus") or
– DB21, ... DBX46.7 (geometry axis 2: Travel command "plus")
● Geometry axis 3:
– DB21, ... DBX52.6 (geometry axis 3: Travel command "minus") or
– DB21, ... DBX52.7 (geometry axis 3: Travel command "plus")
● Orientation axis 1:
– DB21, ... DBX332.6 (orientation axis 1: Travel command "minus") or
– DB21, ... DBX332.7 (orientation axis 1: Travel command "plus")
