Channel block illegal cycle alarm number

A SETAL command has been programmed with a cycle alarm number less than 60 000 or greater than 67 999. Alarm reactions of Siemens standard cycles: Nos. 61,000 -61,999: Interpreter stop; delete with Reset Nos. 62 000 - 62 999: Compensation block; delete with NC Start

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • SETAL command references a cycle alarm number outside the valid range of 60000-67999
  • Typo or incorrect value entered in SETAL instruction during program creation
  • Copy-paste error from another CNC program with different alarm number conventions
  • Mixing standard cycle alarm ranges (61000-61999 or 62000-62999) with invalid SETAL parameters
  • Program generated by CAM software with incorrect alarm number mapping

Troubleshooting Steps

  1. 1Review the part program around the flagged block number and locate the SETAL command with the illegal alarm number
  2. 2Verify the alarm number in the SETAL instruction falls within 60000-67999 range; correct any values outside this window
  3. 3Cross-reference the intended cycle behavior against Siemens standard cycle alarm definitions (61000-61999 for interpreter stop, 62000-62999 for compensation block)
  4. 4Check CAM post-processor settings if program was generated automatically; update to use correct alarm number ranges
  5. 5After correction, reload the program and execute NC Start to clear the alarm and resume operation
