What causes Siemens SINUMERIK alarm 61311?

D offset number not programmed in NC code block before calling measuring cycle. D offset number was deselected or reset by previous program command. Tool offset table entry is empty or undefined for selected tool. Measuring probe tool offset not activated before workpiece measurement cycle. Active tool lost D offset reference due to tool change or reset.

How do I fix Siemens SINUMERIK alarm 61311?

1. Verify NC program includes D offset selection (e.g., D1, D2) immediately before the measuring cycle call 2. Check tool offset table in machine memory to confirm D offset entries exist and contain valid values 3. Review program logic flow to ensure no commands between tool selection and measuring cycle deselect the D offset 4. For workpiece measurement cycles, confirm measuring probe tool offset is activated with correct D number 5. Reload tool offset data or manually re-enter missing D offset values if table entries are corrupted
