A220
Multiple zero offset
selection not allowed
The decoded NC block contains several
mutually exclusive G functions from the zero
offset group (G53 to G59).
Example:
N1 G54 G58
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.
A221
Multiple tool offset
selection not allowed
The decoded NC block contains several
mutually exclusive G functions from the tool
offset selection group (G43/G44).
Example:
N1 G43 G44 D2
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.
A223
Subprogram number
does not exist
The decoded NC block contains a subprogram
call, however the NC program which was
called does not exist in the memory of the
technology.
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
Correct the NC block.
A224
Subprogram nesting
depth not allowed
The permissible nesting depth of subprograms
was exceeded. Recursive calling of
subprograms.
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 program.
The permissible nesting depth for
subprograms is 2 subprogram levels.
