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 touch probes
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.

Press the ERR key. The TNC opens the error
window and displays all accumulated error
messages.
Closing the error window

window.
