Feedback
Once the incremental procedure takes effect, a feedback is sent to the PLC:
● Machine axes:
– DB31, ... DBX65.0 - 65.5 (active machine function: INC1 to INCvar)
● Geometry axes:
– DB21, ... DBX41.0-5 (geometry axis 1: active machine function: INC1 to INCvar)
– DB21, ... DBX47.0-5 (geometry axis 2: active machine function: INC1 to INCvar)
– DB21, ... DBX53.0-5 (geometry axis 3: active machine function: INC1 to INCvar)
● Orientation axes:
– DB21, ... DBX333.0-5 (orientation axis 1: active machine function: INC1 to INCvar)
– DB21, ... DBX337.0-5 (orientation axis 2: active machine function: INC1 to INCvar)
– DB21, ... DBX341.0-5 (orientation axis 3: active machine function: INC1 to INCvar)
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)
