Outputting user error messages

The user has the option of outputting user error messages in the NC program via the #ERROR NC command.

The related error texts are saved to a text file with parameters defined in P-STUP-00169. The output is sent to the log file defined via P-STUP-00170.

Error IDs saved to text file together with the related error texts are only written to the log file.


The range for possible error IDs is 1 – 1000.

Programming Example

Customer-specific error text in log file

Content of user-specific error text file:

455 error text to ID455

The call in the NC program then looks like this:

#ERROR [ID455 RC2 PV1=5 PV2=4.999 PM1=2 PM2=3]

Other information on the #ERROR command: [PROG://User-defined error output]

The output in the log file:
