Siemens 840D 10933 - Channel block contour programm does not contain enough
Channel block contour programm does not contain enough
The contour program contains: - Less than 3 contour blocks with CONTPRON - No contour blocks with CONTDCON
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- Contour program contains fewer than 3 blocks with CONTPRON instruction
- Missing CONTDCON blocks required for contour definition
- Incomplete contour programming syntax or missing required statements
- Contour subprogram called with insufficient geometric data blocks
- Incorrect program structure with premature program termination before contour completion
Troubleshooting Steps
- 1Verify the contour subprogram contains minimum 3 blocks with CONTPRON instructions for contour profile definition
- 2Check that CONTDCON block is present in the contour program to define contour conditions
- 3Review the complete contour program syntax in the referenced channel and block number to ensure all required statements are included
- 4Confirm contour subprogram is called correctly and contains all necessary geometric blocks before any program end statement
- 5Edit the contour program to add missing CONTPRON or CONTDCON blocks according to contour programming requirements, then reload and test
