Siemens 840D 14093 - Channel block path interval <= 0 with polynominal interpolation
Channel block path interval <= 0 with polynominal interpolation
In the polynomial interpolation POLY, a negative value or 0 has been programmed under the keyword for the polynomial length PL=.
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- PL parameter set to zero or negative value in POLY interpolation block
- Incorrect syntax or typo in polynomial length declaration
- Parameter passed from CAM post-processor contains invalid value
- G-code editing error introduced negative or null PL value
- Corruption in part program file affecting parameter values
Troubleshooting Steps
- 1Locate the referenced block in the part program and verify the PL= parameter value is positive and greater than zero
- 2Review the polynomial interpolation syntax: ensure format is correct (POLY PL=<positive_value>)
- 3Check CAM post-processor settings and regenerate the G-code if using automated programming
- 4Verify the part program file for corruption by reviewing surrounding blocks and re-saving in text editor
- 5Test with a known good part program containing POLY interpolation to isolate machine versus program issue
