# ID 120371

Buffer full: too many non-relevant blocks programmed in sequence.
Description | In the CNC program there are too many non-relevant blocks between two motion blocks to be connected via the HSC function (#HSC ON[..]). Non-relevant blocks are all CNC program blocks that contain no motion. These are, for example, blocks resulting from M functions, subroutine calls, dwell times or parameter calculations. With too many non-relevant blocks, the internal buffer memory is not sufficiently large to execute a polynomial calculation or a spline curve.

For more information on the HSC function, see
[PROG// Section: Standard HSC programming]

Response | Class | 2 | Program abort.
Solution | Class | 6 | Check CNC program. In some cases, the problem can be solved by appropriately placing the HSC function selection and deselection outside the ranges using non-relevant blocks.. Otherwise, reduce the number of M functions, subroutine calls and parameter calculations between motion blocks.
Error type | 1, Error message from NC program.
