Fanuc Parameter 1860 Full ((hot))

(which indicates if the absolute position is established via the APZ bit) to maintain the reference point. Manual Absolute (ABS)

On long-travel axes (e.g. 4m+ gantry), the inertia may cause the axis to overshoot the deceleration zone. If the grid point falls beyond the P1860 window, an alarm triggers. Increasing P1860 resolves this. fanuc parameter 1860 full

Sudden jumps or inconsistent "wrap-around" behavior in this parameter can signal a failing encoder or noise in the communication line between the motor and the CNC control . Safety and Modification (which indicates if the absolute position is established

If you can tell me the , which axis is causing trouble (X or Y), and what the surface finish looks like (protrusion or gouge), I can offer a more specific, tailored recommendation for tuning the parameter. If the grid point falls beyond the P1860

: When the machine is homed, the system uses the value in 1860 alongside Parameter 1815
