4.8 The Error Messages
Display of errors
The TNC generates error messages when it detects problems such
as:
„ Incorrect data input
„
Logical errors in the program
„ Contour elements that are impossible to machine
„ Incorrect use of the touch probe system
When an error occurs, it is displayed in red type in the header. Long
and multi-line error messages are displayed in abbreviated form. If an
error occurs in the background mode, the word “Error” is displayed in
red type. Complete information on all pending errors is shown in the
error window.
If a rare “processor check error” should occur, the TNC automatically
opens the error window. You cannot remove such an error. Shut down
the system and restart the TNC.
The error message is displayed in the header until it is cleared or
replaced by a higher-priority error.
An error message that contains a program block number was caused
by an error in the indicated block or in the preceding block.
