Siemens alarm 10750: Channel %1 block %2 tool radius compensation activated without tool number
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
G41/G42 cutter radius compensation was switched on although no valid tool with usable radius data is selected. Without current T/D offset geometry the controller cannot compute the offset contour, so activation is refused. Select a tool with radius data before enabling compensation.
Likely causes
- G41/G42 activated before any T/D selection
- Selected D number contains no radius data (tool type without radius)
- Tool offset table entry cleared or not loaded
