Siemens alarm 10933: Channel %1 block %2 contour program does not contain enough contour blocks
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
A stock-removal contour description was evaluated but contains fewer traversing contour elements than needed to define a machinable profile boundary. At minimum two meaningful contour blocks are required. Enrich or correct the contour subprogram.
Likely causes
- Contour subprogram reduced to a single positioning block
- Blocks commented out or skipped by jumps
- Wrong file selected as the contour description
