Repositioning on the contour via the controlsWith the Repos function it is possible to re-approach theinterruption point by means of the direction keys.2. Repositioning on the contour via the programSeveral approach strategies are available through programcommands: approaching the interruption point, approaching theblock starting point, approaching the block end point, approachinga point on the path between the start of the block and theinterruption point.Retentive memory Data areas in data blocks and times, counters and markers areretentive (non-volatile) if their contents are not lost when the system isrestarted or the mains supply is disconnected.Rigid tapping This function allows threads to be tapped without a compensatingchuck. By using the method whereby the spindle, as a rotary axis, andthe drilling axis interpolate, threads can be cut to a precise final drillingdepth (e.g. for blind hole threads) (requirement: spindles in axisoperation).Rotary axis Rotary axes rotate a workpiece or tool to a defined angular position.Rotary axis,continuously turningDepending on the application, the traversing range of a rotary axiscan be selected to be limited to less than 360 degrees or to beendlessly turning in both directions.Endlessly-turning rotary axes are used for non-circular turning,grinding, and winding.Rotation Component of a -> frame which defines a rotation of the coordinatesystem through a specific angle.Rounding axis Rounding axes rotate a workpiece or tool to an angular positioncorresponding to an indexing grid. When a grid index is reached, therounding axis is "in position".SS7 configuration S7 configuration is a tool with the aid of which modules can beparameterized. With S7 configuration, various -> parameter blocksof the -> CPU and the I/O modules are set on the -> programmingunit. These parameters are transmitted to the CPU.
