Commanded abort block number not found.
Description | When ordering a NC program start, a block number (Nxx) unequal to zero (nil) can be declared, which defines the real point of program abortion. The corresponding block number is also searched for in subroutines. The message (warning) is output, if the declared block number has not been found until main program end M30.
Response | Class | 1 | NC program processing until M30.
Solution | Class | 1 | Check the NC program for the commanded block number and complete it if applicable. Note: NC blocks without block number are always executed during the search. So if you use this function, please attach to all relevant NC blocks a unique block number.
Parameter | %1: | Current value [-]
Commanded abort block number.
Error type | 1, Error message from NC program.
