Channel Block: Program reset required

NC reset required. Alarm is triggered: all measuring cycles except for CYCLE973, CYCLE976. Remedy: Execute NC reset.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Measuring cycle interruption or abnormal termination preventing proper program state recovery
  • Active measuring cycle (other than CYCLE973 or CYCLE976) still running when reset attempted
  • NC kernel state mismatch requiring full reset to clear measuring cycle context
  • Machine safety interlock or emergency stop activated during active measurement operation

Troubleshooting Steps

  1. 1Execute full NC reset via control panel or NC_RESET command to clear measuring cycle state
  2. 2Verify no measuring cycles other than CYCLE973 or CYCLE976 are active or queued in the part program
  3. 3Check machine safety interlocks and emergency stop status; reset if necessary before proceeding
  4. 4Review NC error log and program memory for incomplete or interrupted measurement operations
  5. 5If alarm persists after reset, restart control system and reload part program from scratch
