Fanuc Parameter 1860 Full ((exclusive)) Jun 2026

Type using the keypad and press the [No. SRH] (Number Search) soft key.

Increase 1860 by 10–20% increments. Also verify that the motor torque limit (parameter 1640/1641) is adequate.

is defined as the Reference Position Shift Value on the Z-axis (or the axis to which it is assigned). In many standard Fanuc configurations (especially on lathes and machining centers with absolute encoders), Parameter 1860 holds the distance (in detection units) that the machine moves to find its Grid Point during a reference return operation. fanuc parameter 1860 full

After replacing a servo motor or ballscrew, the machine shakes during G01 moves. The new components have different inertia. Calculate the new inertia ratio (parameter 2047/2048) first, then reduce 1860 by 20% as a starting point, then fine-tune upward.

$$ 1860 = \frac\textGear Ratio (Motor to Ball Screw) \times \textReference Counter (1821)\textFeed Gear Ratio $$ Type using the keypad and press the [No

Because rapid traverse rates are significantly faster than cutting feedrates, the value in Parameter 1860 is almost always set much higher than the value in Parameter 1828 to accommodate the natural lag caused by high-speed acceleration. Data Structure and Input Specifications

Most manufacturers set this between 20 and 100 ( Also verify that the motor torque limit (parameter

Detection units (the smallest increment the machine can move).

: When the machine is powered on, the CNC reads the value from the absolute encoder and reconciles it with the value stored in Parameter 1860 to determine the exact machine position. Common Technical Scenarios Battery Failure
