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

Program execution stop.

Solution

Class

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.
