By fine-tuning parameter 1860, users can optimize the advanced preview function to suit specific machining requirements, such as:
Parameter 1860 is used only when:
: It stores the absolute position data for each controlled axis. Absolute Encoders : This parameter works in conjunction with Parameter 1815 (specifically the fanuc parameter 1860 full
In a perfectly functioning machine, this parameter stays at "1" indefinitely. However, certain events will force it to "0," requiring a re-homing procedure: By fine-tuning parameter 1860, users can optimize the
Decrease 1860 gradually (5 ms at a time) until corners sharpen and cycle time improves, but before vibration appears. | Machine Type | Typical 1860 Value (mm/min)
| Machine Type | Typical 1860 Value (mm/min) | Reason | |--------------|-----------------------------|--------| | Small milling | 500 – 2000 | Short deceleration zone, slower dog approach | | Large lathe | 2000 – 6000 | Heavy axis, needs consistent dog capture | | High-speed machining center | 1000 – 4000 | Balanced speed vs. repeatability | | Grinder | 200 – 1000 | Very fine reference accuracy required |
