Sinumerik Alarm 10751 Channel %1 block %2 danger of collision due to tool radius compensation
%1 = Channel number
%2 = Block number, label
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.
– Local alarm reaction.
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.
– NC Stop on alarm at block end.
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.
Clear alarm with NC START or RESET key and continue the program.
