Channel %1 block %2 G function %3 is unknown
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Source string
Definitions:
With indirectly programmed G functions, an invalid or non-allowed group number has been
programmed. Allowed group number = 1. and 5 max. number of G groups. In the displayed block, a
non-defined G function has been programmed. Only "real" G functions are checked, which begin with
the address G, e.g. G555. "Named" G functions such as CSPLINE, BRISK etc. are interpreted as
subroutine names.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM
CORRECT. The correction pointer positions on the incorrect block. You should decide on the basis of
the machine manufacturer's programming guide whether or not the displayed G function exists or is
available, or whether a standard G function has been reconfigured (or introduced by an OEM).
Remove G function from the part program or program function call in accordance with the machine
manufacturer's programming guide.
Program
Clear alarm with NC START or RESET key and continue the program.
Continuation:

Channel %1 block %2 invalid G function number %3 programmed
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = G code number
Definitions:
A non-allowed G function number (parameter 3) has been programmed for a G group with indirect G
code programming. Only the G function numbers indicated in the Programming Guide
"Fundamentals", Section 12.3 "List of G functions/Path conditions" are allowed.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Modify part program.
Program
Clear alarm with NC START or RESET key and continue the program.
Continuation:
12480
Channel %1 block %2 subroutine %3 already defined
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Source string
Definitions:
The name used in the PROC or EXTERN instruction has already been defined in another call
description (e.g. for cycles).
Example:
EXTERN CYCLE85 (VAR TYP1, VAR TYP2, ...)
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM
CORRECT. The correction pointer positions on the incorrect block. A program name must be selected
that has not yet been used as identifier. (Theoretically, the parameter declaration of the EXTERN
instruction could also be adapted to the existing subroutine in order to avoid the alarm output.
However, it would have been defined identically twice).
Program
Clear alarm with NC START or RESET key and continue the program.
