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.
5422 EXCESS VELOCITY IN G43.4/G43.5
(M series)
As a result of pivot tool length compensation, an attempt was made to
move the tool along an axis at a feedrate exceeding the maximum cut-
ting feedrate.
5425 ILLEGAL OFFSET VALUE (M series) The offset number is incorrect.
5430 ILLEGAL COMMAND IN 3–D CIR
(M series)
In a modal state in which three–dimensional circular interpolation can-
not be specified, a three–dimensional circular interpolation
(G02.4/G03.4) is specified. Alternatively, in three–dimensional circular
interpolation mode, a code that cannot be specified is specified.
5432 G02.4/G03.4 FORMAT ERROR
(M series)
A three–dimensional circular interpolation command (G02.4/G03.4) is
incorrect.
5433 MANUAL INTERVENTION IN 3–D
CIR (M series)
In three–dimensional circular interpolation mode (G02.4/G03.4), manu-
al intervention was made when the manual absolute switch was on.
5435 PARAMETER OUT OF RANGE
(TLAC) (M series)
Incorrect parameter setting (set value range)
5436 PARAMETER SETTING ERROR 1
(TLAC) (M series)
Incorrect parameter setting (setting of the rotation axis)
5437 PARAMETER SETTING ERROR 2
(TLAC) (M series)
Incorrect parameter setting (setting of the tool axis)
5440 ILLEGAL DRILLING AXIS
SELECTED (M series)
The drilling axis specified for the drilling canned cycle is incorrect.
The G code command block of the canned cycle does not specify the
Z point of the drilling axis. When there is a parallel axis with the drilling
axis, the parallel axis is also specified at the same time.
