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