Offizielle Schritte zur Fehlerbehebung

Parameters: %1 = Channel number %2 = Block number, label %3 = T number or T identifier %4 = Program name Definitions: A tool identifier which the NCK does not recognize was programmed. Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Remedy: If the program pointer is at an NC block which contains the specified T identifier: If the program is incorrect, remedy the error with a correction block and continue the program. If the data block is missing, create one. You can do this by downloading a data bl ock with all the defined D numbers onto the NCK (via MMC with overstore) and continue the program. If the program pointer is at an NC block which does not contain the specified T identifier: The error occurred at an earlier point in the program where the T command appeared, but the alarm was not output until the change command was detected. If the program is incorrect - T5 programmed instead of T55 - the current block can be corrected with a correction block; i.e. if only M06 is entered, you can correct the block with T55 M06. The incorrect T5 line remains in the program until it is terminated by a RESET or end of program. In complex program structures with indirect progr amming, it may not be possible to correct the program. In this case, you can only intervene locally with an overstore block - with T55 in the example. If the data block is missing, create one. You can do this by downloading the data block of the tool with all the defined D numbers onto the NCK (via MMC wi th overstore), program the T command with overstore, and continue the program. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
