Fanuc Alarm 1092 - DUPLICATE MACRO-CALL WORD
Alarm 1092 occurs when multiple macro call instructions (G65/G66/G67 or user macro calls) are specified within a single NC program block. The Fanuc control can only execute one macro call per block and flags this as a programming error when it detects duplicate or conflicting macro call commands in the same line.

Root Cause Summary
Alarm 1092 occurs when multiple macro call instructions (G65/G66/G67 or user macro calls) are specified within a single NC program block. The Fanuc control can only execute one macro call per block and flags this as a programming error when it detects duplicate or conflicting macro call commands in the same line.
Causes and Fixes
- 1
At the MDI/EDIT screen, press PRGRM key and locate the block number where alarm 1092 occurred. The cursor will typically be positioned at the error line.
- 2
Examine the block for multiple G65 or G66 commands. Example of error: 'G65 P1000 A10 G65 P2000 B20'. Identify which macro calls are duplicated.
- 3
Separate macro calls into individual blocks. Correct format: 'G65 P1000 A10;' on one line, then 'G65 P2000 B20;' on the next line.
- 4
Reset the alarm by pressing RESET key, then re-run the program in single block mode to verify correct macro execution sequence.
Call a technician if:
- ·Alarm persists after correcting program syntax
- ·Macro parameter settings need modification
- ·Custom macro programs require debugging
Prevention
- Always use one macro call per program block
- Validate program syntax before loading
- Use consistent macro call formatting
- Check parameter 6050 macro call settings
Common Mistakes
- Combining G65 and M98 in same block
- Multiple G65 calls without block separation
- Incorrect spacing in macro parameter assignments
- Copy-paste errors creating duplicate calls
