Siemens alarm 10930: Channel %1 block %2 interpolation type not allowed in stock removal contour
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
Within a stock removal contour description (contour subprogram for CYCLE95-style roughing) an interpolation type other than linear and circular elements was found. Contour definition accepts only simple G0/G1/G2/G3-type elements in one plane. Remove helix, spline or polar interpolations from the contour program.
Likely causes
- Helical or spline blocks inside the contour subprogram
- Polar-coordinate blocks used in contour definition
- Cycle calling the wrong program as contour description
