ID 50852

Maximum shift value exceeded.

Description

In connection with the #SHIFT function, a shift value greater than the predefined maximum shift value has resulted from the current conditions due to the programmed geometry, the technology parameters and the measurement. The CNC has insufficient motion information to execute the shift operation.

Execute the definition of the maximum shift value taking into consideration the programmed NC block lengths and the parameters of the motion look-ahead in the interpolator. This includes any active geometric smoothing/block segmentation functions for motion blocks.

The maximum shift value should be set as small as possible.

The channel-specific look-ahead function is parameterised in

The channel-specific look-ahead function is parameterised in
P-CHAN-00650 and P-CHAN-00653, (alternatively P-STUP-00070 and P-STUP-00071).

FCT_SHIFT_NCBL must be active for P-CHAN-00650 in order to use the function:

configuration.interpolator.function FCT_IPO_DEFAULT | FCT_SHIFT_NCBL

Response

Class

4

Movement stop.

Solution

Class

6

Check and correct the parameter setting of the look-ahead:P-CHAN-00650 / P-CHAN-00653, (alternatively P-STUP-00070 / P-STUP-00071).

Correct the maximum shift value or the programmed geometry
