PS030

Review the part program line where PS030 triggered. Identify the offset number specified (e.g., G54.1 P125, H99, D150).

Navigate to OFFSET/SETTING > SETTING screen. Check current parameter 5001 (number of work zero offsets) and parameters 5003/5004 (number of tool offsets). For extended work offsets, verify parameter 5004 bits configure G54.1 P~ range.

Access SYSTEM > PARAM and verify parameter 5001 (work offset quantity, typical range 6-300), parameter 5003 (geometry offset count), and parameter 5004 (wear offset count). For 0i/30i/31i/32i series, check parameter 6300#0-#2 for extended offset configuration.

Either modify the program to use valid offset numbers within the configured range, or increase parameter 5001/5003/5004 values if additional offsets are needed and memory allows. Power cycle required after parameter change.

Increasing offset memory parameters may require additional memory option or license key (G54.1 extended offsets typically require option/license verification in SYSTEM > PARAM > 8131-8136)

Press SYSTEM soft key, navigate to PARAM screen, and check parameter 6300#0 (extended work offset enable). Verify it is set to 1 if using G54.1 P7 and higher.

Check SYSTEM > OPTION screen (may be under SYSTEM > PMC > PARAM > OPTION depending on series). Verify if extended work offset option is listed and enabled. Common option codes include Work Offset Expansion or Additional Work Offsets.

If option is not present, either modify program to use standard G54-G59 range, or contact machine tool builder/Fanuc to enable extended offset option with proper license key installation.

Enabling extended offsets may require software upgrade or paid option unlock. Document current parameter 8131-8136 (option board settings) before contacting support.

If option is enabled but PS030 persists, verify parameter 5001 is set to accommodate the required offset count (e.g., G54.1 P100 requires parameter 5001 ≥ 100). Adjust parameter 5001 accordingly and perform full power cycle.

Parameter 5001 maximum value depends on control series and memory configuration. 0i-series typically max 300, 30i/31i/32i can support 500+ with proper options.

Navigate to SYSTEM > DIAGNOSIS and check diagnostic 0303 (battery voltage). Low voltage (<2.6V on most systems) indicates backup battery failure and potential parameter corruption. Replace battery if voltage is low.

After battery replacement, all parameters, offsets, and PMC data must be reloaded from backup. Machine will require complete parameter restoration.

Access SYSTEM > PARAM and visually inspect parameters 5001, 5003, 5004 for unrealistic values (e.g., 0, excessively high numbers like 9999). Compare to OEM specification sheet or identical machine.

If corruption detected, restore parameters from known good backup using SYSTEM > FILE or memory card. Load all parameters file (*ALL.PAR or PALL.001) from OEM backup media.

Loading ALL parameters will overwrite servo tuning, PMC ladder, and offset data. Ensure complete system backup exists before proceeding.

After parameter restoration, perform full power cycle (AC power off for 30 seconds minimum). Re-verify offset access and clear PS030 alarm by pressing RESET key after power-up.
