Too many non-relevant blocks in sequence while spline is active.

Description

The CNC program contains too many non-relevant blocks between two motion blocks to be connected by spline interpolation. Non-relevant blocks are all CNC program blocks that contain no motion. 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 executed.

The spline is activated by:

• G151 or #SPLINE ON (B spline or Akima)
• #HSC ON [BSPLINE …]

For more information on spline interpolation, see
[PROG// Section: B spline interpolation]
[PROG// Section: Akima spline interpolation]

Response

Class

2

Program abort.

Solution

Class

6

Check CNC program, reduce the number of M functions, subroutine calls and parameter calculations between spline interpolation motion blocks.

Error type

1, Error message from NC program.
