Buffer FIFO full.

Description

The CNC program contains too many non relevant blocks between two motion blocks to be connected by spline interpolation (G151). Non-relevant blocks are all CNC program blocks that contain no movement. These are, for example, blocks resulting from M function subroutine calls or parameter calculations. With too many non relevant blocks, internal buffer memory is not sufficient and spline interpolation cannot be done.

For more information on spline interpolation see

Response

Class

2

Program execution stop.

Solution

Class

6

Check CNC program, reduction of M codes, subroutine calls and parameter calculation between spline interpolation motion blocks.

Error type
