# ID 120371

Buffer FIFO full.
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 movement. These are, for example, blocks resulting from M functions, subroutine calls, dwell times or parameter calculations. Because of limited internal buffer memory polynomial or spline calculation cannot be done.

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

Response | Class | 2 | Program execution stop.
Solution | Class | 6 | Check CNC program. In some cases, the problem can be solved by appropriately placing the HSC function select and deselect outside the ranges with non-relevant blocks.. Otherwise reduction of M codes, subroutine calls and parameter calculation between motion blocks has to be done.
Error type | 1, Error message from NC program.
