Fanuc Parameter List Upd -

| Parameter Number(s) | Function / Adjustment | Notes & Common Applications | | :--- | :--- | :--- | | | I/O Channel | Sets the data interface used for data transfer (0: RS232, 4: CF Card, 17: USB). | | 103 | Baud Rate | Sets the communication speed for RS232 transfer (11:9600 bps, 12:19200 bps). | | 1320 / 1321 | Software Limits (+) | Set the machine's maximum travel limits in positive (+) and negative (-) directions. | | 1420 | Rapid Traverse Rate | Defines the G00 rapid speed for each axis. | | 1422 | Maximum Cutting Feedrate | Defines the maximum allowed speed for all cutting movements (G01, G02, G03). | | 1815 | APC / Absolute Position | Often used to set or reset the machine's reference point position. | | 1825 | Position Loop Gain | Adjusts the rigidity and servo response of an axis; must be balanced between axes for accuracy. | | 1851 | Backlash Compensation (G01) | Compensates for mechanical play (backlash) during cutting movements. | | 1852 | Backlash Compensation (G00) | Compensates for mechanical play (backlash) during rapid traverse movements. | | 4077 | Spindle Orientation Stop | Fine-tunes the angular stop position of the spindle for tool changes. | | 6071-6079 | User-defined M-codes | Assigns a custom program number to an unused M-code (e.g., setting M-code 100 to run O9010). |
