Parameters: %1 = Channel number %2 = Block number, label %3 = Index Definitions: A function was programmed or triggered which is not allowed in the current program context. The code of the function in question is encoded in the "index" parameter: Index == 1: "RET" command was programmed in the main program level Index == 2: Conflict between "Cancel level"/" Clear number of passes" and "Implicit GET" Index == 3: Conflict ASUB start immediately after selection of overstore (up to P3) Index == 4: MD10760 $MN_G53_TOOLCORR = 1: SUPA/G153/G53 programmed in G75 Index == 5: POSRANGE command not programmed in synchronized action Index == 6: SIRELAY command not programmed in synchronized action Index == 7: GOTOF/GOTOB/GOTO command progra mmed with string variable in synchronized action. Index == 8: COA application "cutting generator" not active Reaction: Interpreter stop NC Start disable in this channel. Interface signals are set. Alarm display. Remedy: Index == 1: Substitute "RET" command with M17/M30 Index == 2: Insert an auxiliary block (e.g. M99) after the subroutine call to which the "Cancel level"/"Clear number of passes" refers Index == 3: Overstore an auxiliary block (e.g. M99), then start ASUB (up to P3) Index == 4: With MD10760 $MN_G53_TOOLCORR = 1: Do not activate SUPA/G53/G153 in the G75 block Index == 5: Program POSRANGE command in synchronized action Index == 6: Program SIRELAY command in synchronized action Index == 7: Program GOTOF/GOTOB/GOTO command with block number or label Index == 8: Load COA application "cutting generator" Program Continuation: Clear alarm with the RESET key.
