A206
4th G-function not
allowed
The NC block which was read in contains an
illegal 4th G function.
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values - decoder error location"
task.
Effect:
The axis movement is inhibited or stopped via
the deceleration ramp.
- MDI mode:No 4th G function is allowed.
- Automatic/single-block mode:Define a legal
4th G function according to the table (see the
Programming Guide).
A208
D-number is not
allowed
A D number greater than 20 was found in the
decoded NC block.
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values - decoder error location"
task.
Effect:
The axis movement is inhibited or stopped via
the deceleration ramp.
Correct the NC block.
A210
Interpolation of 3 axes
not allowed
The decoded NC block contains an
interpolation of 3 or more axes.
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values - decoder error location"
task.
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
Correct the NC block. Only 2D interpolation is
allowed.
A211
Shortest distance G68
and G91 not allowed
G function G68 (shortest path for rotary axis)
was detected in the decoded NC block,
although G91 (incremental dimensions) is
active.
Example: N10 G91 G68 X20.000
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values - decoder error location"
task.
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
Correct the NC block.Function G68 can only
be programmed in association with G90
(absolute dimensions).
