NoteCorner limit angle and compressor function COMPCADThe corner limit angle for COMPCAD set via the setting data SD42470$SC_CRIT_SPLINE_ANGLE is only used as an approximate measure for corner detection.By evaluating the plausibility, the compressor can also identify flatter block transitions ascorners and larger angles as outliers.Recommended settingsThe following machine data has an effect on the compressor functions. We recommend settingthe following values:Number Identifier RecommendedvalueMD18360 $MN_MM_EXT_PROG_BUFFER_SIZE 100MD20490 $MC_IGNORE_OVL_FACTOR_FOR_ADIS 1MD28520 $MC_MM_MAX_AXISPOLY_PER_BLOCK 3MD28530 $MC_MM_PATH_VELO_SEGMENTS 5MD28540 $MC_MM_ARCLENGTH_SEGMENTS 10MD28060 $MC_MM_IPO_BUFFER_SIZE 100MD28070 $MC_MM_NUM_BLOCKS_IN_PREP 60MD32310 $MA_MAX_ACCEL_OVL_FACTOR operation>ProgrammingSyntaxCOMPONCOMPCURVCOMPCADCOMPOFMeaningCOMPON: Activating the compressor function COMPONEffective: ModalCOMPCURV: Activating the compressor function COMPCURVEffective: ModalCOMPCAD: Activating the compressor function COMPCADEffective: ModalCOMPOF : Deactivating the currently active compressor function.See alsoTolerance and compression of G0 blocks (Page 235)B1: Continuous-path mode, Exact stop, Look Ahead4.5 Compressor functionsBasic FunctionsFunction Manual, 01/2015, 6FC5397-0BP40-5BA2 229
