Overview of Alarms
NCK alarms
12000 Channel %1 block %2 address %3 programmed repeatedly
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source string of the address
Definitions: Most addresses (address types) may only be programmed once in an NC block, so that the block
information remains unambiguous (e.g. X... T... F... etc. - exception: G and M functions).
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.
- Remove from the NC program addresses that occur more than once (except for those where multiple
value assignments are allowed).
- Check whether the address (e.g. the axis name) is specified via a user-defined variable (this may not
be easy to see if allocation of the axis name to the variable is performed in the program through
computational operations only).
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12010 Channel %1 block %2 address %3 address type programmed too often
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Source string of the address
Definitions: For each address type, it is defined internally how often it may occur in a DIN block (for instance, all
axes together form one address type for which a block limit also applies).
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.
The program information must be split up over several blocks (but make sure that the functions are of
the non-modal type!).
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12020 Channel %1 block %2 illegal address modification
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Valid address types are 'IC', 'AC', 'DC', 'CIC', 'CAC', 'ACN', 'ACP', 'CACN', 'CACP'. Not each of these
address modifications can be used for each address type. The Programming Guide specifies which
of these can be used for the various address types. If this address modification is applied to address
types that are not allowed, then the alarm is generated, e.g.:
N10 G02 X50 Y60 I=DC(20) J30 F100
interpolation parameters with DC.
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.
Apply non-modal address modifications only for permissible addresses, in accordance with the
Programming Guide.
Program Clear alarm with NC START or RESET key and continue the program.
