Sub-movementsThere are maximum 4 sub-movements in case of soft retraction and approach with thefollowing positions:● Start point of the movement P0● Intermediate points P1, P2 and P3● End point P4Points P0, P3 and P4 are always defined. Intermediate points P1 and P2 can be omitted, accordingto the parameters defined and the geometrical conditions.On retraction, the points are traversed in the reverse direction, i.e. starting at P4 and endingat P0.18.5.4.2 ParametersThe response of the smooth approach and retraction function is determined by up to 9parameters:Non-modal G code for defining the approach and retraction contourThis G code cannot be omitted.● G147: Approach with a straight line● G148: Retraction with a straight line● G247: Approach with a quadrant● G248: Retraction with a quadrant● G347: Approach with a semicircle● G348: Retraction with a semicircle3ZKHQDSSURDFKLQJZLWKDVWUDLJKWOLQH*3ZKHQDSSURDFKLQJZLWKDTXDGUDQW*3ZKHQDSSURDFKLQJZLWKDVHPLFLUFOH*7RROFHQWHUSRLQWSDWK7RROFHQWHUSDWK7RROFHQWHUSDWK7RRO 7RRO&RQWRXU &RQWRXU&RQWRXU7RRO3 3',653',653',6533Figure 18-16 Approach behavior depending on G147 to G347 and DISR (with simultaneous activationof tool radius compensation)W1: Tool offset18.5 Tool radius compensation 2D (TRC)Basic Functions1410 Function Manual, 01/2015, 6FC5397-0BP40-5BA2
