Alarm 10227

Siemens 10227 - [up to SW 3.x only] Channel : command aborted

Alarm 10227 occurs on older Siemens 840D systems (SW 3.x and earlier) when an NC command or function is aborted unexpectedly during execution. This typically results from program syntax errors, conflicting commands, incorrect mode selections, or interruptions during synchronized actions like tool changes or axis movements.

Root Cause Summary

Alarm 10227 occurs on older Siemens 840D systems (SW 3.x and earlier) when an NC command or function is aborted unexpectedly during execution. This typically results from program syntax errors, conflicting commands, incorrect mode selections, or interruptions during synchronized actions like tool changes or axis movements.

Safety

  • Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.

Causes and Fixes

  1. 1

    Identify the exact block number where the alarm occurred by checking the alarm message detail and channel display.

  2. 2

    Review the NC program at and around the alarm block for syntax errors, missing mandatory parameters, or incomplete command structures (G-codes, M-codes, positioning commands).

  3. 3

    Check for conflicting modal commands in the same block or sequential blocks (e.g., multiple motion types, incompatible cycles).

  4. 4

    Correct the program syntax, verify with simulation mode, then reset the alarm and restart the program from a safe position.

    Always perform a dry run after program modifications to prevent collisions.
