Number ContentsMessage
5402 SPL:ILLEGAL AXIS MOVING
(M series)
A movement is made along an axis that is not the spline interpolation
axis.
For example, in three–dimensional tool compensation mode using an
offset vector of which components are the X–, Y–, and Z–axes, when
two–axis spline interpolation is performed with the two spline axes set
to the X– and Y–axes, a movement along the Z–axis occurs, resulting
in this alarm.
5403 SPL:CAN NOT MAKE VECTOR
(M series)
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.
5405 ILLEGAL PARAMETER IN G41.2/
G42.2 (M series)
The parameter setting that determines the relationship between the
rotation axis and rotation plane is incorrect.
5406 G41.3/G40 FORMAT ERROR
(M series)
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 sup-
pressed.
5407 ILLEGAL COMMAND IN G41.3
(M series)
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.
5408 G41.3 ILLEGAL START_UP
(M series)
1) In a mode of group 01 except G00 and G01, G41.3 (startup) is speci-
fied.
2) At startup, the included angle of the tool direction vector and move
direction vector is 0 or 180 degrees.
5409 ILLEGAL PARAMETER IN G41.3
(M series)
The parameter setting (No. xxxx to xxxx) that determines the relation-
ship between the rotation axis and rotation plane is incorrect.
5411 NURBS:ILLEGAL ORDER (M series) The number of steps is specified incorrectly.
5412 NURBS:NO KNOT COMMAND
(M series)
No knot is specified. Alternatively, in NURBS interpolation mode, a
block not relating to NURBS interpolation is specified.
5413 NURBS:ILLEGAL AXIS COMMAND
(M series)
An axis not specified with controlled points is specified in the first block.
5414 NURBS:ILLEGAL KNOT (M series) The number of blocks containing knots only is insufficient.
5415 NURBS:ILLEGAL CANCEL
(M series)
Although NURBS interpolation is not completed yet, the NURBS inter-
polation mode is turned off.
5416 NURBS:ILLEGAL MODE (M series) A mode that cannot be used with NURBS interpolation mode is speci-
fied in NURBS interpolation mode.
5417 NURBS:ILLEGAL MULTI–KNOT
(M series)
As many knots as the number of steps are not specified at the start and
end points.
5418 NURBS:ILLEGAL KNOT VALUE
(M series)
Knots do not increase in monotone.
5420 ILLEGAL PARAMETER IN G43.4/
G43.5 (M series)
A parameter related to pivot tool length compensation is incorrect.
5421 ILLEGAL COMMAND IN G43.4/
G43.5 (M series)
In pivot tool length compensation (type 2) mode, a rotation axis is speci-
fied.
