Remedy:
Generally reduce the number of symbols in the affected block (possibly by using the array technique or by using R
parameters), or adapt the corresponding machine data (see below).
MD28020 $MC_MM_NUM_LUD_NAMES_TOTAL with error in LUD blocks (i.e. if more variable definitions were made
in the active part program than allowed by the MD).
GUD data blocks can cause errors as part of the 'initial.ini download' process (e.g. in the case of a series start-up) or
by selective activation via PI service _N_F_COPY (activate GUD via HMI dialog). If alarm 15180 refers to a GUD def-
inition file, then MD18120 $MN_MM_NUM_GUD_NAMES_NCK or MD18130 $MN_MM_NUM_GUD_NAMES_CHAN
is set to a value that is too small.
Macros are loaded during POWER ON/NCK RESET or selectively via PI service _N_F_COPY (activate macro via HMI
dialog). If alarm 15180 refers to a macro definition file, then MD18160 $MN_MM_NUM_USER_MACROS is set to a
value that is too small.
Cycle program definitions (PROC instruction) are reloaded at each POWER ON/NCK RESET. In case of failure check
parameter %3 to find out whether the name of the cycle program has caused the error - in this case, the value of
MD18170 $MN_MM_NUM_MAX_FUNC_NAMES should be increased, or whether the name of a cycle call parameter
has caused the error - in this case, the value of MD18180 $MN_MM_NUM_MAX_FUNC_PARAM should be
increased.
Program
Clear alarm with NC START or RESET key and continue the program.

[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 pro-
grammed. 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 cor-
rection pointer positions on the incorrect block. You should decide on the basis of the machine manufacturer's pro-
gramming 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.

[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 program-
ming. Only the G function numbers indicated in the Programming Guide "Fundamentals", Section 12.3 "List of G func-
tions/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.
