Fanuc Parameter 1860 Full Updated Instant

| Feature | Detail | |---------|--------| | | 1860 (axis 1), 1861 (axis 2), … | | Purpose | Final approach speed for G28 reference return | | Units | mm/min (metric) or 0.1 inch/min (inch) | | Typical range | 500 – 6000 mm/min | | Key constraint | Must be ≤ parameter 1420 (Rapid) | | Failure mode if too high | Missed reference signal → alarm or position drift | | Failure mode if too low | Long cycle time, but safe |

The CNC will likely show an alarm (e.g., PS100). This is normal. Press the [SYSTEM] key. Press the [PARAM] soft key. Locate Parameter 1860: Type 1860 and press [NO. SEARCH] . fanuc parameter 1860 full

FANUC Parameter 1860 embodies the complexity and power of CNC parameters: its function is entirely context-dependent. On modern 16i/18i systems, it stores rotary axis reference points. On 0i-MC controls, it governs acceleration for backlash compensation. On older 18MC machines, it may represent a gear ratio component. And during absolute encoder resets, it functions as a temporary placeholder cleared to zero, then automatically rewritten. | Feature | Detail | |---------|--------| | |

The machine adds extra motion (governed by parameters 1851/1852) to compensate for the gap. Press the [PARAM] soft key
