Table of dynamic weightings (dynamic_weighting[i].*)
The channel parameters of the CNC contain a table which defines weighting factors for the dynamic characteristics (v, a, tr) depending on the contour path. The weighting factor of a table index entry is used when the contour path is smaller than the associated motion path limit value in the table. If the contour path is equal to the motion path limit value, the dynamic factors of the next index entry are used.
Structure name | Index |
dynamic_weighting[i] | i = 0 .. 9 (maximum number of table entries: 10, application-specific) |
The following further conditions must be considered when defining further definitions:
- the motion path limit in the table increases as index values become larger.
- The axes which form the contour path for dynamic weighting must be marked accordingly (P-AXIS-00015). Weighting is only executed for these axes.
- The weighting factor is limited to a minimum value of 1%. For ramp time, the minimum ramp time tr_min (P-AXIS-00201) must also be considered as the lower limit value.
- Weighting is possible upwards to the maximum value of vb_max (P-AXIS-00212) and a_max (P-AXIS-00008). With ramp time tr_grenz (P-AXIS-00200) the weighting has no upper limit.
