Channel %1 block %2 maximum number of symbols exceeded with %3
%1 = Channel number
%2 = Block number, label
%3 = Source string
The max. number of variable definitions (GUD, LUD), macro definitions, cycle programs
and/or cycle parameters that the controller's data management system is able to handle
has been exceeded. If this alarm occurs in conjunction with alarm 15175 (cycles were
loaded again), not enough memory is available. This situation can be remedied by modify-
ing the machine data. If this alarm occurs in conjunction with alarm 15180 (initial.ini down-
load failed), then this alarm shows the name of the block causing the error. (For a list of
names and their meaning -> please refer to alarm 6010)
- Correction block
- Interface signals are set.
- Alarm display.
Please inform authorized personnel / the service department. Reduce the symbols in the
block (possibly by using the array technique or by using R parameters), or adapt the
machine data (if you have access rights). $MC_MM_NUM_LUD_NAMES_TOTAL with
error in LUD blocks (i.e. if more variable definitions were made in the active part programs
than allowed by the MD). GUD data blocks can only cause errors as part of the 'initial.ini
download' process. Macros and cycle program definitions are reloaded at each POWER
ON/NCK-RESET. This means that these blocks can only cause errors in conjunction with
this process. See also the explanations for alarm 6010. Particularly in relation to the
reloading of cycle programs, users with the necessary expertise can check parameter %3
to find out:
• Whether the name of the cycle program has caused the error - in this case the value of
machine data $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 machine data $MN_MM_NUM_MAX_FUNC_PARAM should be increased.
If it is impossible to tell what the parameter mentioned in %3 belongs to, both machine
data values should be increased or successively one after the other.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 G function %3 is unknown
%1 = Channel number
%2 = Block number, label
%3 = Source string
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.
- Correction block
- Interface signals are set.
- Alarm display.
Press the NC Stop key and select the function "Correction block" with the softkey PRO-
GRAM 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.
Clear alarm with NC START or RESET key and continue the program.
