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 | Number of look-ahead blocks in the interval [ 10; P-CHAN-00653]. |
FCT_SYNC | Synchronising an axis in coordinated motion |
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 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. |
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 |
