Arithmetical error in
APPR/DEP
230 n Calculation of an APPR or DEP
block before or after a helix resulted
in an arithmetic error.
n Check the input values.
If necessary change the starting
point.
Arithmetical error in
APPR/DEP
238 n Calculation of the approaching or
departing path with APPR LCT or
DEP LCT in the Contour Train cycle
resulted in an arithmetical error.
n Check the input values.
n If necessary, use another tool
radius.
Arithmetical error in
CR
232 n Calculation of the circle center of a
"circle with radius" block in a
contour pocket resulted in an
arithmetical error.
n Check the coordinates in the CR
block (ISO: G2,G3 with R).
Arithmetical error in
CT
233 n Calculation of a "circle with tangent"
block in a contour pocket resulted in
an arithmetical error.
n Check the coordinates in the CT
block (ISO: G6, G16).
Arithmetical error
during M112
250 n Calculation of automatically
inserted rounding arcs (M function
M112) resulted in an arithmetic
error.
n Check input values for M112 .
Arithmetical error in
RND/CHF
234 n Calculation of a rounding arc or
chamfer in a contour pocket
resulted in an arithmetic error.
n Check the input values in the
chamfer or rounding block.
n If necessary, use another tool
radius.
Arithmetical error in
rough-out
231 n Calculation of a rounding arc for
contour-parallel rough-out resulted
in an arithmetic error.
n Change the starting point.
n If necessary, use another tool
radius.
Oversize greater
than depth
448 n SL cycles II: Allowance for floor is
greater than milling depth.
n Check Q4 in cycle 20 (ISO: G120).
Autostart not
enabled
3205 n You have attempted to activate the
autostart function even though it
was not enabled by the machine
tool builder.
n Contact your machine tool builder.
Contouring disabled
by PLC
3056 n In your NC program you have
programmed a movement to be
executed in more than one axis.
However, contouring operation has
been disabled by the PLC.
n Edit the NC program so that it
contains only paraxial line blocks.
Path comp wrongly
ended
253 n You attempted to cancel radius
compensation in a circle block (with
R0, ISO: G40).
n The tool radius compensation can
be activated only with a line block
(L, ISO: G0, G1, G10, G11).
Path comp wrongly
started
254 n You attempted to program a
chamfer before tool radius
compensation was started.
n A chamfer may only be
programmed if tool radius
compensation is active.
Path comp wrongly
started
255 n You attempted to program a corner
radius before tool radius
compensation was started.
n A corner radius may only be
programmed if tool radius
compensation is active.
Path comp wrongly
started
256 n You attempted to activate tool
radius compensation in a circle
block (with RL or RR, ISO: G41 or
G42).
n The tool radius compensation can
be activated only with a line block
(L, ISO: G0, G1, G10, G11).
Path comp wrongly
started
257 n You attempted to program a corner
radius between a part-program
block without radius compensation
and a line block with tool radius
compensation.
n Program a corner radius only with
active tool radius compensation.
Path comp wrongly
started
258 n You attempted to take over a pole
(or circle center) after the first block
with tool radius compensation
(empty CC block, ISO: G29).
n The pole can be taken over no
earlier than in the second block
with tool radius compensation.
Path comp wrongly
started
259 n You tried to program an APPR block
with tool radius compensation
active.
n APPR block is permitted only when
no tool radius compensation is
active.
