2238 In the Circular Pocket Finishing
cycle (Cycle 212, ISO: G212), you
entered a finished-part diameter
(Q223) smaller than the workpiece-
blank diameter (Q222).
2049 Circular pattern cycle: You entered
a pitch circle diameter of zero.
2050 Circular pattern cycle: Enter a
stopping angle equal to the starting
angle.
2829 In a measuring cycle you entered
in parameter Q247 an angular step
of 0.
1144 Paraxial radius compensation
(R+/R-, ISO: G43/G44) is not
permitted when M120 is active.
425 During resumption of a part
program a tool radius compensation
is active RL/RR (ISO: G41, G42)
although a PLC datum shift must
be executed.
2636 You activated M128 while a tool
radius compensation RL/RR (DIN/
ISO: G41/G42) was still active.
The TNC cannot switch from 2-D
to 3-D radius compensation.
267 You programmed four axes and
a tool radius compensation in an
L block, but the TNC can move no
more than three axes with radius
compensation.
M112 not permitted for circular
movement.
1143 You cannot change the tool radius
compensation while M120 is active.
You programmed a tool radius
compensation RR/RL in an LN
block, but the TNC will calculate
the compensation from the normal
vector NX, NY, NZ.
3026 The TNC cannot execute radius
compensation on the programmed
contour. Possible cause: You
programmed two tangentially
connecting straight lines in
sequence.
370 You programmed a radius-
compensated single-axis
positioning block which without
the radius compensation does not
result in tool movement (e.g. IX+0
R+, ISO: G7).
371 You programmed a radius-
compensated single-axis
positioning block whose path
would take a direction opposite to
that of the non-compensated path.
372 You attempted to run a part
program block with tool radius
compensation after inserting a
spherical or toroidal cutter.
Corrective action
Edit Q222 in the cycle definition.
Correct the pitch circle diameter in
the cycle.
Correct the starting or stopping
angle in the cycle.
Enter an angular step (Q247) other
than 0.
Edit the part program.
Cancel tool radius compensation
before resuming the program.
If you wish to run a 3-D radius
compensation, you must first
program M128 and then the tool
radius compensation with RL/RR
(ISO:G41/G42).
Remove one of the four axes or
the radius compensation.
Deactivate M112 with M113.
Edit the part program.
Delete RR/RL from the LN block.
Correct the contour.
Edit the part program.
Edit the part program.
Set R2 to equal 0 in the tool
table = 0.
