P-STUP-00060 | Defining functionalities for path preparation. |
Description | This parameter defines the individual functionalities for path preparation. The individual functions can be enabled or disabled for testing or for performance reasons. |

Path preparation function table
Identifier | Description |
FCT_DEFAULT | The functions FCT_FFM | FCT_PRESEGMENTATION | FCT_SPLINE | FCT_POLY | FCT_CAX | FCT_CAX_TRACK | FCT_SEGMENTATION are available. |
FCT_FFM | Free-form surface mode, #HSC [OPMODE 1 CONTERR 0.01], #HSC [OPMODE 2] |
FCT_PRESEGMENTATION | Linear pre-segmentation in HSC mode |
FCT_SPLINE | #HSC[], AKIMA, B-Spline, G150/G151 |
FCT_POLY | #CONTOUR MODE[], G61, G261/G260 |
FCT_CAX | C axis processing, i.e. the spindle is embedded in the NC channel. |
FCT_CAX_TRACK | #CAXTRACK, tracking an axis according to the contour angle |
FCT_SEGMENTATION | For dynamic segmentation of the path contour, e.g. if the curvature of a polynomial segment varies significantly. |
The following functions must also be enabled: | |
FCT_LIFT_UP | Automatic lifting/lowering of an axis (path-based coupling). |
FCT_EMF | Edge machining (sharp angle contours). |
FCT_EMF_POLY_OFF | Edge machining inactive with polynomials. Contrary to the setting with FCT_EMF, edge signal generation is masked when path polynomial generation is active in the channel. Polynomials are generated for smoothing G261 or when B Spline is active. The resulting geometry is then tangential. Example: FCT_DEFAULT | FCT_EMF_POLY_OFF |
FCT_SYNC | Synchronise an axis to a path group. |
FCT_PRECON | Optimised planning using #HSC[BSPLINE]. |
FCT_LIFT_UP_TIME | Automatic lifting/lowering of an axis (time-based coupling). |
FCT_PTP | Dynamically optimised smoothing of the complete contour. |
FCT_M_PRE_OUTPUT | Pre-output of M/H functions (microjoints). |
FCT_SURFACE | HSC machining with Surface Optimiser |
FCT_SEG_CHECK | Block segmentation in combination with path-controlled offset of M functions (dwell time), |
FCT_NIBBLING | Activate the nibbling function |
FCT_PUNCHING | Activate the punching function |
FCT_VSM | Activate the velocity smoothing function |
P-STUP-00070 | Definition of interpolator functionalities |
Description | This parameter defines individual functionalities and the size of the look-ahead buffer in the interpolator, i.e. it defines the number of blocks to calculate deceleration distance and dynamic planning. |
Parameter | configuration.channel[i].interpolator.function |
Data type | STRING |

FCT_SHIFT_NCBL | Path-controlled offset of M functions (dwell time). |

FCT_CONTOUR_LAH | Contour look-ahead: advance output of motion blocks to the PLC |
FCT_DYN_POS_LIMIT | Dynamic limitation of axis positions |
FCT_EXTENSION_EQUIDIST | Die-sinking EDM Orbiting |
FCT_CALC_POS_V_0 | Calculating and supplying the braking distance on the path until velocity and acceleration are 0. Supplying CNC objects on the path and assigned PCS and ACS axis positions at the end of this deceleration process. |
FCT_DLM | Activate the conveyor tracking function. |
