Start-up parameters
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 |
Data range | See Description. |
Dimension | ---- |
Default value | FCT_IPO_DEFAULT |
Remarks |

P-STUP-00071 | User-specific size of look-ahead buffer |
Description | This parameter permits the user-defined definition of the number of NC blocks in the look-ahead buffer. The parameter is only evaluated if P-STUP-00070 is set with FCT_LOOK_AHEAD_CUSTOM. |
Parameter | configuration.channel[i].interpolator.number_blocks_lah * |
Data type | UNS32 |
Data range | 0 ... 10000 |
Dimension | ---- |
Default value | 120 |
Remarks | As of Build V2.11.20 and higher, the default size of the look-ahead buffer is 70 blocks. As of Build V2.11.28 and higher, the default size is 120 blocks. As the size increases, the additional calculations make greater demands on the controller hardware. As of Build V3.1.3067.07 the upper limit of the data range is 500 blocks. If #SLOPE[TYPE=STEP] is used, the upper limit is 10000 blocks as of Build V3.1.3060.0.
