An axis not specified with controlled points is specified in the first block.

No knot is specified. Alternatively, in NURBS interpolation mode, a
block not relating to NURBS interpolation is specified.

The number of steps is specified incorrectly.

The parameter setting (No. xxxx to xxxx) that determines the relationship
between the rotation axis and rotation plane is incorrect.

1) In a mode of group 01 except G00 and G01, G41.3 (startup) is specified.
2) At startup, the included angle of the tool direction vector and move
direction vector is 0 or 180 degrees.

1) A G code that belongs to group 01 except G00 and G01 is specified
in G41.3 mode.
2) An offset command (a G code belonging to group 07) is specified in
G41.3 mode.
3) The block next to G41.3 (startup) contains no movement.

1) A G41.3 or G40 block contains a move command.
2) A G1.3 block contains a G code or M code for which buffering is suppressed.

The parameter setting that determines the relationship between the
rotation axis and rotation plane is incorrect.

Three-dimensional tool compensation vectors cannot be generated. When a three-dimensional tool compensation vector is created for
the second or subsequent point, that point, previous point, and next
point are on the same straight line, and that straight line and the three-
dimensional tool compensation vector for the previous point are in
parallel. When a three-dimensional tool compensation vector is created at the
end point of smooth interpolation or spline interpolation, the end point
and the point two points before are the same.
