DBB4 (feedrate override); channel-specificDB31, ...DBX2.2 Delete distance-to-go, axis-specificEdge evaluation: Yes Signal(s) updated: CyclicSignal state 1 or edgechange 0 → 1The axis-specific distance-to-go of the positioning axis is canceled. The positioning axis isdecelerated and the following error is eliminated. The programmed end position is deemed tohave been reached. The path axes are not influenced by the axis-specific "delete distance-to-go" interface signal. The channel-specific "delete distance-to-go" interface signal is used forthis purpose.Special cases,errors, ...If the axis-specific "delete distance-to-go" interface signal is enabled, even if no positioningaxes have been programmed in this block, the NCK does not respond.Corresponding to ...
