program number and block number where the
block decoder detected an error.
Effect:
NC program execution is inhibited or aborted.
Moving axes are stopped via the deceleration
ramp.

Counter-measure
-Transfer the program to the technology.
-Select the correct program number.
The permissible range for program numbers is
between 1 and 200.
The program number must not be changed
while the program is running.
Correct the block.
The last block in the sequence must contain
the following block identifier "0".
Specify an existing main program number.
For the block search function, the selected
program number [PROG_NO] must be
specified as the program number for the main
program.
For the block search function, an existing
program number must be specified as the
subprogram number for level 1 or level 2.
For the block search function, the subprogram
number specified in the NC block must be
specified as the subprogram number for level
1.
For the block search function, the subprogram
number specified in the NC block must be
specified as the subprogram number for level
2.
