Defining interpolator functionalities (P-CHAN-00650)
P-CHAN-00650 | 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 required to calculate deceleration distance and dynamic planning. |

Identifier | Description |
FCT_IPO_DEFAULT | FCT_LOOK_AHEAD_STANDARD |
FCT_LOOK_AHEAD_LOW | 30 blocks |
FCT_LOOK_AHEAD_STANDARD | 120 blocks |
FCT_LOOK_AHEAD_HIGH | 190 blocks |
FCT_LOOK_AHEAD_CUSTOM | Any number of look-ahead blocks in the interval [ 0; 200]. Specification by parameter P-CHAN-00653. |
FCT_SYNC | Synchronisation of an axis on a path group. |
FCT_LOOK_AHEAD_OPT | The path velocity curve can be further improved for HSC machining by additional calculations. This generally reduces machining time. The additional calculations place greater demands on the controller hardware. |
FCT_LIFT_UP_TIME | Automatic lifting/lowering of an axis (time-based coupling). |
FCT_SHIFT_NCBL | Path-controlled offset of M functions (dwell time). |
FCT_CALC_STATE_AT_T | Calculation of path velocity at a time in the future. Function only available in combination with HSC slope and only as of V3.1.3057.0 |
FCT_CALC_TIME | Calculation of interpolation time to next feed block (G01,G02,G03). |
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 Planetary expansion |
The look-ahead buffer size values specified above apply as of CNC Builds V2.11.2800 and higher; the following settings apply to CNC Build V2.11.20xx:
FCT_LOOK_AHEAD_LOW | 30 blocks |
FCT_LOOK_AHEAD_STANDARD | 70 blocks |
FCT_LOOK_AHEAD_HIGH | 120 blocks |
