Overview of Alarms
NCK alarms
10750 Channel %1 block %2 tool radius compensation activated without tool
number
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A tool T... must be selected so that the control can make allowance for the associated compensation
values.
A correction data block (D1) containing the correction values (parameter P1 - P25) is automatically
assigned to each tool (T number). Up to 9 correction data blocks can be assigned to a tool by
specifying the required data block with the D number (D1 - D9).
The cutter radius compensation (CRC) is allowed for if function G41 or G42 is programmed. The
correction values are contained in parameter P6 (geometry value) and P15 (wear value) of the active
correction data block Dx.
Reaction: Correction block is reorganized.
Interpreter stop
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Before calling the CRC with G41/G42, program a tool number under the address T...
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10751 Channel %1 block %2 danger of collision due to tool radius
compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The "Bottleneck detection" (calculation of intersection for the following compensated traversing
blocks) has not been able to calculate a point of intersection for the reviewed number of traversing
blocks. It is therefore possible that one of the equidistant paths violates the workpiece contour.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Please inform the authorized personnel/service department. Check the part program and modify the
programming if possible such that inside corners with smaller paths than the correction value are
avoided. (Outside corners are not critical because the equidistants are lengthened or intermediate
blocks are inserted so that there is always a point of intersection).
Increase the number of reviewed traversing blocks via machine data 20240
CUTCOM_MAXNUM_CHECK_BLOCKS (default: 3), resulting in an increase in the extent of
calculation and therefore also the block cycle time.
Program Clear alarm with NC START or RESET key and continue the program.
