Channel block more than two angles programmed with ROTS or

Frame rotations are described using space angles with the language commands ROTS or AROTS. A maximum of two angles can be programmed.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Programmer used three or more rotation angles in a single ROTS or AROTS command when only two are permitted
  • Incorrect syntax in frame rotation programming with excessive angle parameters
  • CAM-generated code containing unfiltered rotation angle data exceeding the two-angle limit
  • Misunderstanding of space angle definition requirements for frame rotations in part program

Troubleshooting Steps

  1. 1Locate the alarm-indicated block number in the part program and review the ROTS or AROTS command syntax
  2. 2Count the number of angle parameters programmed in the problematic rotation command; identify and remove any angles beyond the first two
  3. 3Verify proper frame rotation syntax: ROTS or AROTS should contain a maximum of two space angles; consult Siemens 840D programming documentation for correct format
  4. 4If using CAM software, check postprocessor settings and output filters to ensure frame rotation commands are not generating excess angle parameters
  5. 5Re-test the corrected block by single-stepping or dry-running the program to confirm the alarm no longer appears
