. This process "syncs" the mechanical position with the value now stored in 1860. For detailed technical specifications, refer to the Fanuc Series 0i-MODEL F Plus Parameter Manual Series 16i/18i Parameter Manual using these parameters? FANUC? M6 toolchange position. | Practical Machinist

In FANUC CNC systems, . It works in direct synchronization with parameters 1861 and 1862 to establish and store the exact mechanical position of an axis utilizing an absolute PulseCoder.

serves as a vital configuration setting in modern Fanuc CNC controllers, explicitly dictating the Reference Position (or Grid Position) Parameters used during absolute position encoder initialization and synchronization . Working hand-in-hand with core homing coordinates like Parameter 1815 (APC/APZ) and Parameter 1850 (Grid Shift), Parameter 1860 records and maintains the reference system's pulse data requirements. Correct manipulation of this parameter ensures that your CNC machine tracks its absolute physical coordinate system flawlessly, eliminating tool-change collisions, axis drift, and costly downtime.

: These define the coordinate values of the 1st through 4th reference positions in the machine coordinate system. Parameter 1850 : Often confused with 1860, this is the Grid Shift

Working with parameters like 1860 brings you into the very core of the machine's positioning logic. A few final points to keep in mind: It works in direct synchronization with parameters 1861

| Machine Type | Rigidity | Typical 1860 Range (ms) | | :--- | :--- | :--- | | Small VMC (BT30) | High | 30–60 | | Large VMC (BT40/BT50) | Medium | 60–120 | | Heavy-duty lathe (X-axis) | Medium | 80–150 | | Gantry mill (heavy slide) | Low | 120–250 | | High-speed machining center | Very High | 10–40 |

Decrease 1860 gradually (5 ms at a time) until corners sharpen and cycle time improves, but before vibration appears. When respected and set correctly

When a machine uses a linear scale (like Heidenhain or FANUC linear scales) mounted directly to the machine casting, it is a full-closed loop system. Here, Parameter 1860 must be calculated manually based on physical mechanics.

Parameter 1860 is a small, unassuming number that connects the physical world of machine mechanics to the digital world of CNC logic. Understanding its function helps demystify the absolute encoder setup process and is crucial for troubleshooting reference point alarms. When respected and set correctly, it is one of the key pillars of a reliable and accurate CNC machine tool.

Reference position updating is not performed . This forces the control system to bypass automatic synchronization updates when crossing the coordinate boundary. This setting is mandatory when an external feedback scale lacks structural rotation data markers and relies strictly on continuous physical accumulation. 2. Interaction with Related Parameters

Parameter 1860 is defined as a bit-type or axis-specific variable depending on the exact generation of your FANUC control system (such as the Series 0i, 16i, 18i, or 31i). Its primary behavior centers around the or reference point updating logic. The Core Setting Logic
