Parameter 1860 — Fanuc

Improperly setting this parameter can lead to inaccurate machining or damage.

When a machine axis homes using a reference point return method (like G28), it looks for a physical deceleration switch and then shifts to the next "grid shift" pulse sent by the encoder. Parameter 1860 allows the operator or technician to electronically offset this final reference position without moving physical switches or mechanical components.

Do not try to manually "tune" or "guess" the value of Parameter 1860 when setting up absolute encoders. Always follow the clearing and referencing procedure to let the system populate it correctly. Improperly setting this parameter can lead to inaccurate

Always take a full SRAM or ALLPARAM backup to a PCMCIA card or USB drive before changing any parameter in the 1000–2000 range.

In CNC systems (specifically Series 16i, 18i, 21i, and 0i), Parameter 1860 is a critical, axis-specific value that stores the absolute position encoder data .
