5403 SPL:CAN NOT MAKE
VECTOR
(M series)
Three–dimensional tool compensation
vectors cannot be generated.
· When a three–dimensional tool com-
pensation vector is created for the se-
cond 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 com-
pensation 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 suppressed.
5407 ILLEGAL COMMAND IN
G41.3
(M series)
1) A G code that belongs to group 01 ex-
cept G00 and G01 is specified in G41.3
mode.
2) An offset command (a G code belong-
ing to group 07) is specified in G41.3
mode.
3) The block next to G41.3 (startup) con-
tains 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 specified.
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 (PRM19610–19619)
that determines the relationship between
the rotation axis and rotation plane is incor-
rect.
5411 NURBS:ILLEGAL ORDER
(M series)
The number of steps is specified incorrect-
ly.
5412 NURBS:NO KNOT
COMMAND
(M series)
No knot is specified. Alternatively, in
NURBS interpolation mode, a block not re-
lating 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 com-
pleted yet, the NURBS interpolation mode
is turned off.
5416 NURBS:ILLEGAL MODE
(M series)
A mode that cannot be used with NURBS
interpolation mode is specified 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.
