Path offset wrongly ended
Do not cancel electrode radius compensation in a block with a circular
path.
Path offset wrongly started
Use the same radius compensation before and after a RND and CHF
block.
Do not begin electrode radius compensation in a block with a circular
path.
CYCL incomplete
Define the cycles with all data in the proper sequence.
Do not call the coordinate transformation cycles.
Before calling a cycle, define Cycle 12 PGM CALL.
BLK FORM definition incorrect
Program the MIN and MAX points according to the instructions.
Choose a ratio of sides that is less than 64:1.
If you call another program (PGM CALL), copy the BLK FORM to the
main program.
Axis double programmed
Each axis can have only one value for position coordinates.
Plane wrongly defined
Do not change the electrode axis while a basic rotation is active.
Correctly define the main axes for a circular arc.
Define both main axes for CC.
Wrong axis programmed
Do not attempt to program locked axes.
Do not mirror rotary axes.
Enter a positive chamfer length.
Chamfer not permitted
A chamfer block must be located between two straight-line blocks with
identical radius compensation.
No editing of running program
A program cannot be edited while it is being transmitted or executed.
Gross positioning error
The TNC monitors positions and movements. If the actual position
deviates excessively from the nominal position, this blinking error
message is displayed. To correct the error, do a ”warm start” by holding
down the END key for a few seconds.
Circle end position incorrect
Enter complete information for connecting arc.
Enter end points that lie on the circular path.
Label number not found
Only call label numbers that have been set.
PGM section cannot be shown
Enter a smaller electrode radius.
Movements in a rotary axis cannot be graphically simulated.
Enter an electrode axis for simulation that is the same as the axis in the
BLK FORM.
Rounding-off undefined
Enter tangentially connecting arcs and rounding arcs correctly.
Rounding radius too large
Rounding arcs must fit between contour elements.
Key non-functional
This message always appears when you press a key that is not needed
for the current dialog.
