PS0060

Press PRGRM key and verify the active program number displayed on screen matches the intended program. Check program content for existing N-numbers using cursor or search function.

If restarting after interruption, carefully review the program listing to confirm the exact N-number format. Fanuc requires exact match including leading zeros if programmed (N0100 vs N100).

Press RESET to clear PS0060 alarm, then re-initiate sequence number search with verified N-number using PROG search soft key or restart function.

Check parameter 3107#0 (N number skip) - if set to 1, the control skips N-numbers during search. Set to 0 for standard N-number search functionality.

Changing parameter 3107 requires parameter write enable (PWE) via parameter 3202#0=1 and may require cycle power

Open the program in EDIT mode (PRGRM > EDIT) and scroll through to verify presence or absence of N-numbers in the G-code. Programs from Mastercam, Fusion360, and other CAM packages frequently omit N-numbers.

If restart is required, use block restart function instead: Position tool manually to safe restart point, then use RESTART soft key and specify restart by block number or line position rather than N-number.

Ensure proper modal conditions (G-codes, offsets, tool) are established before restart to prevent crashes

For future operations requiring N-numbers, edit CAM post-processor to output sequence numbers at critical locations (tool changes, subprogram calls) or add manually in EDIT mode.

Navigate to SYSTEM > PARAM and check parameter 3107#0 (NSR - N number search restriction). When set to 1, N-numbers are skipped during search. Verify setting matches operational requirements.

Parameter modification requires PWE active and may affect other program search behaviors

Verify parameter 3107#1 (NSB - N number stop) and parameter 3107#2 settings. These control N-number search behavior during single block and optional block skip operations.

Check parameter 0000 (I/O channel) and parameter 0020 (TV check) to ensure program is being read correctly from memory. Corrupted program data can cause search failures.

Press RESET, cycle power to CNC if parameter changes were made, then reload program and attempt N-number search again. Verify alarm clears and search completes successfully.

Cycling power will abort any active machining operation and clear tool offsets in volatile memory on older controls
