Fanuc Parameter 1860 May 2026

Parameter 1860 is far more than a simple number in a FANUC parameter list. It is a precision tuning tool that balances cycle time against positional repeatability. Too high, and you risk inconsistent homing and alarms. Too low, and you waste seconds on every startup—seconds that add up to hours of lost productivity over a machine's lifetime.

In Fanuc systems equipped with absolute encoders, the control must maintain a constant "knowledge" of where each axis is located, even after the power is cycled. While defines the status of the detector (such as whether it is enabled or if the home position is set), Parameter 1860 actually holds the numerical position data that corresponds to the mechanical position of the machine. Function: Stores the absolute position data for each axis. Parameter 1860 is far more than a simple

: Used to enable the absolute pulse coder (Bit 5: APC) and confirm if the reference position has been set (Bit 4: APZ). Too low, and you waste seconds on every

This parameter is a critical internal value that represents the absolute position of the axis relative to the reference point (home). When a machine is equipped with absolute encoders, it "remembers" its position even after being powered off. Parameter 1860 acts as the digital record of that specific physical location on the encoder's scale. Role in Absolute Homing
