Number / Alarm Cause
A206 The NC block which was read in contains an
illegal 4th G function.
4th G-function not
allowed 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.
A208 A D number greater than 20 was found in the
decoded NC block.
D-number is not
allowed 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.
A210 The decoded NC block contains an
interpolation of 3 or more axes.
Interpolation of 3 axes
not allowed 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.
A211 G function G68 (shortest path for rotary axis)
was detected in the decoded NC block,
Shortest distance G68 although G91 (incremental dimensions) is
and G91 not allowed 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.

Counter-measure
-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).
Correct the NC block.
Correct the NC block. Only 2D interpolation is
allowed.
Correct the NC block.
Function G68 can only be programmed in
association with G90 (absolute dimensions).
