Boundary conditions3.2 Boundary conditions for standard functionsSpecial functions: Retrace Support (TE7)36 Function Manual, 11/2006, 6FC5397-2BP10-2BA03.2.4 Block searchBlock search with calculationRESU is subject to the following supplementary conditions in the context of the block searchwith calculation (on contour/at end of block) standard function:• The last CC_PREPRE(x) RESU part program command run during the block search iseffective in the target block.• The retraceable contour range starts with the REPOS approach block.Block search without calculationCC_PREPRE(x) RESU part program commands have no effect during block searcheswithout calculation.3.2.5 TransformationsMeaningRESU can also be used for active kinematic transformation (e.g. 5-axis transformation)subject to restrictions, as the traversing movements of the first two geometry axes on thechannel are recorded in the basic coordinate system (BCS) and therefore before thetransformation.Transformation changeoverWhile RESU is active, no transformation changes are permitted to take place andtransformation must not be activated/deactivated.RESU is active:• Start: Part program command CC_PREPRE(1)• End: Program end or part program command CC_PREPRE(-1)You will find a complete description of the transformations in:References:/FB2/ Function Manual for Extended Functions, Kinematic Transformation (M1)/FB3/ Function Manual for Special Functions, Transformation Package Handling (TE4)
