Fanuc Parameter 1860 [upd] Full Jun 2026

Technicians often confuse 1860 with other parameters. Here is a clear comparison:

: If the absolute encoder batteries die or the encoder cable is disconnected, the relationship between the mechanical position and the encoder data is lost. Re-establishing the home position will result in a new value being written to Parameter 1860. Grid Shift Correlation Parameter 1850 fanuc parameter 1860 full

This is not an error, but a reminder. Set PWE back to 0. Technicians often confuse 1860 with other parameters

Therefore, you would to the existing Parameter 1860. Grid Shift Correlation Parameter 1850 This is not

, then counter capacity = 4000 pulses. The CNC will think one motor rev = 4000 pulses, causing the reference point to occur twice per physical motor revolution → unstable grid.

If the axis is physically "stuck" or binding, the motor might struggle to settle into the final position window.
